what is a viva voce presentation

• PhD Viva Voces – A Complete Guide
• Doing a PhD
• A PhD viva involves defending your thesis in an oral examination with at least two examiners.
• The aim of a PhD viva is to confirm that the work is your own , that you have a deep understanding of your project and, overall, that you are a competent researcher .
• There are no standard durations, but they usually range from one to three hours, with most lasting approximately two hours .
• There are six outcomes of a PhD viva: (1) pass without corrections (2) pass subject to minor corrections, (3) pass subject to major corrections, (4) downgrade to MPhil with no amendments, (5) downgrade to MPhil subject to amendments, (6) immediate fail.
• Almost all students who sit their viva pass it, with the most common outcome being ‘(2) – pass subject to minor corrections’.

What Is a PhD Viva?

A viva voce , more commonly referred to as ‘viva’, is an oral examination conducted at the end of your PhD and is essentially the final hurdle on the path to a doctorate. It is the period in which a student’s knowledge and work are evaluated by independent examiners.

In order to assess the student and their work around their research question, a viva sets out to determine:

• you understand the ideas and theories that you have put forward,
• you can answer questions about elements of your work that the examiners have questions about,
• you understand the broader research in your field and how your work contributes to this,
• you are aware of the limitations of your work and understand how it can be developed further,
• your work makes an original contribution, is your own and has not been plagiarised.

Note: A viva is a compulsory procedure for all PhD students, with the only exception being when a PhD is obtained through publication as opposed to the conventional route of study.

Who Will Attend a Viva?

In the UK, at least two examiners must take part in all vivas. Although you could have more than two examiners, most will not in an attempt to facilitate a smoother questioning process.

One of the two examiners will be internal, i.e. from your university, and the other will be external, i.e. from another university. Regardless, both will be knowledgeable in your research field and have read your thesis beforehand.

In addition to your two examiners, two other people may be present. The first is a chairperson. This is an individual who will be responsible for monitoring the interview and for ensuring proper conduct is followed at all times. The need for an external chairperson will vary between universities, as one of the examiners can also take on this role. The second is your supervisor, whose attendance is decided upon by you in agreement with your examiners. If your supervisor attends, they are prohibited from asking questions or from influencing the outcome of the viva.

To avoid any misunderstandings, we have summarised the above in a table:

Note: In some countries, such as in the United States, a viva is known as a ‘PhD defense’ and is performed publicly in front of a panel or board of examiners and an open audience. In these situations, the student presents their work in the form of a lecture and then faces questions from the examiners and audience which almost acts as a critical appraisal.

How Long Does a Viva Last?

Since all universities have different guidelines , and since all PhDs are unique, there are no standard durations. Typically, however, the duration ranges from one to three hours, with most lasting approximately two hours.

Your examiners will also influence the duration of your viva as some will favour a lengthy discussion, while others may not. Usually, your university will consult your examiners in advance and notify you of the likely duration closer to the day of your viva.

What Happens During a Viva?

Regardless of the subject area, all PhD vivas follow the same examination process format as below.

Introductions

You will introduce yourselves to each other, with the internal examiner normally introducing the external examiner. If an external chairperson is present, they too are introduced; otherwise, this role will be assumed by one of the examiners.

Procedure Explained

After the introductions, the appointed chair will explain the viva process. Although it should already be known to everyone, it will be repeated to ensure the viva remains on track during the forthcoming discussion.

Warm-Up Questions

The examiners will then begin the questioning process. This usually starts with a few simple opening questions, such as asking you to summarise your PhD thesis and what motivated you to carry out the research project.

In-Depth Questions

The viva questions will then naturally increase in difficulty as the examiners go further into the details of your thesis. These may include questions such as “What was the most critical decision you made when determining your research methodology ?”, “Do your findings agree with the current published work?” and “How do your findings impact existing theories or literature? ”. In addition to asking open-ended questions, they will also ask specific questions about the methodology, results and analysis on which your thesis is based.

Closing the Viva

Once the examiners are satisfied that they have thoroughly evaluated your knowledge and thesis, they will invite you to ask any questions you may have, and then bring the oral examination to a close.

What Happens After the Viva?

Once your viva has officially ended, your examiners will ask you to leave the room so that they can discuss your performance. Once a mutual agreement has been reached, which can take anywhere from 10 minutes to an hour, you will be invited back inside and informed of your outcome.

PhD Viva Outcomes

There are six possible outcomes to a viva:

• Immediate award of degree: A rare recommendation – congratulations, you are one of the few people who completely satisfied your examiners the first time around. You do not have to do anything further at this point.
• Minor amendments required: The most common recommendation – you obtain a pass on the condition that you make a number of minor amendments to your thesis, such as clarifying certain points and correcting grammatical errors. The time you have to make these changes depends on the number of them, but is usually one to six months.
• Major amendments required: A somewhat uncommon recommendation – you are requested to make major amendments to your thesis, ranging from further research to collecting more data or rewriting entire sections. Again, the time you have to complete this will depend on the number of changes required, but will usually be six months to one year. You will be awarded your degree once your amended thesis has been reviewed and accepted.
• Immediate award of MPhil: An uncommon recommendation – your examiners believe your thesis does not meet the standard for a doctoral degree but meets the standard for an MPhil (Master of Philosophy), a lower Master’s degree.
• Amendments required for MPhil: A rare recommendation – your examiners believe your thesis does not meet the standard for a doctoral degree, but with several amendments will meet the standard for an MPhil.
• Immediate fail: A very rare recommendation – you are given an immediate fail without the ability to resubmit and without entitlement to an MPhil.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

What Is the Pass Rate for Vivas?

Based on an  analysis of 26,076 PhD students  who took their viva exam between 2006 and 2017, the PhD viva pass rate in the UK is 96%; of those who passed, about 80% were required to make minor amendments to their thesis. The reason for this high pass rate is that supervisors will only put their students forward for a viva once they confidently believe they are ready for it. As a result, most candidates who sit a viva are already well-versed in their PhD topic before they even start preparing for the exam.

How Do I Arrange a Viva?

Your viva will be arranged either by the examiners or by the chairperson. The viva will be arranged at least one to two months after you have submitted your thesis and will arrange a viva date and venue that is suitable for all participants.

Can I Choose My Examiners?

At most universities, you and your supervisor will choose the internal and external examiners yourselves. This is because the examiners must have extensive knowledge of the thesis topic in order to be able to examine you and, as the author of the thesis in question, who else could better determine who they might be than you and your supervisor. The internal examiner is usually quite easy to find given they will be from your institution, but the external examiner may end up being your second or third preference depending on availability.

Can I Take Notes Into a Viva?

A viva is about testing your competence, not your memory. As such, you are allowed to take notes and other supporting material in with you. However, keep in mind that your examiners will not be overly impressed if you constantly have to refer to your notes to answer each question. Because of this, many students prefer to take an annotated copy of their thesis, with important points already highlighted and key chapters marked with post-it notes.

In addition to an annotated copy of a thesis, some students also take:

• a list of questions they would like to ask the examiners,
• notes that were created during their preparation,
• a list of minor corrections they have already identified from their viva prep work.

How Do I Prepare for a PhD Viva?

There are several ways to prepare for a PhD viva, one of the most effective being a mock viva voce examination . This allows you to familiarise yourself with the type of viva questions you will be asked and identify any weak areas you need to improve. They also give you the opportunity to practise without the pressure, giving you more time to think about your answers which will help to make sure that you know your thesis inside out. However, a mock viva exam is just one of many methods available to you – some of the other viva preparation methods can be found on our “ How to Prepare for a PhD Viva ” page.

Ace Your Viva Presentation: Tips and Tricks

The thought of an oral presentation can be a huge source of stress and anxiety for many students, while some just blossom in such situations. If you’re one of the former, though, don’t panic. With decent preparation and practice, you too can successfully master your viva presentation.

But first: what is a viva presentation?

Viva voce is a Latin phrase most often translated as “by word of mouth.”  In academic circles, a viva presentation is an oral exam in which you defend your thesis.

After the thesis is defended, it’s discussed by a small panel. Among those present are the examining professors, but there may also be research assistants, members of the relevant department or even fellow students.

The purpose of this defense is to show examiners how knowledgeable you are on your research topic, that you have internalized what you have learned and know how to apply it.  In effect, it shows that you are well prepared to enter into academic discussion.

In principle, the viva presentation won’t make an entire grade’s difference, but it can tip the proverbial scale in your favor. It does offer some major advantages: You can clear up any ambiguities, assuage any doubts your examiners may have, and show that your stand by your research.

Preparation is key

After months or even years of hard work, the thesis is finished, the last formatting mistakes corrected, the bibliography painstakingly checked one last time and hooray, it’s finished! Time to celebrate! And then you get an invitation to the viva …

So, the wine bottle is re-corked and it’s back to the desk. But the good news is: you’ve actually already done most of the preparation. That’s what all the in-depth research you did to create your thesis was. You’re already an expert on your topic, so now you just need to explain it to your examiners clearly and calmly. That’s why it doesn’t make sense to start preparing for your viva before your thesis is finished and you’ve answered all your own questions.

Your supervisor should already know what to expect and the purpose of the viva is to present your results. Some people just hand in their thesis with huge relief and then put the whole thing out of their mind for a while.

This isn’t necessarily a problem but when the viva presentation is due, you really need to give yourself time to familiarize yourself with the topic again. Re-read your thesis a few times to get your results and methods fresh in your mind and you’ve already done much of the prep work for your viva.

Organizational details

You need to check the examination regulations of your institution to find out what will be required of you during your viva presentation. How long should the presentation last? Who will be present? How will the discussion group be structured at the end? Studies have shown that anxiety is significantly lessened if you know exactly what to expect. Don’t ignore these details.

Make sure you have the right power supply for the projector and whether your slide format is compatible with the projector. An article on slide formats and the difference between 4:3 and 16:9 can be found here .

Know how long your presentation should be. This often depends on what type of work you’re presenting. Be sure to keep this in mind as you create your slides.

Also, think about whether or not you want to provide a handout. Even if it isn’t explicitly required, examiners will often use a handout as a guide when asking their questions, allowing you to better control the discussion that follows.

You can find helpful tips on handouts here .

Lastly, think about what you’re going to wear for your viva presentation. If you’re not sure, take a cue from your examiners. If they wear a suit or dress to other viva presentations, it’s safe to assume that the dress code for your viva will be on the formal side. It’s important to look neat and tidy, but you should also feel comfortable. The wrong shoes or clothing that is too tight can negatively impact the way you present. You can find more helpful tips on clothing here .

Technical details

The most popular tool for giving a viva presentation is PowerPoint. On the day of your presentation, get there early to make sure your devices are working. It also helps to be familiar with PowerPoint’s features, such as Presenter View. This fantastic tool will help you stay on track during your viva presentation. For more information on Presenter View, click here .

In general, the rule for viva presentations is: Keep It Simple . This is a defense of your academic research and your slides should express that. Keep it classic and factual. Use a uniform font and a neutral, preferably white, background. You can use backgrounds from PresentationLoad:

In principle, you should use as little text and as few key points as possible, but it’s also essential to document your research accurately. Room for interpretation can be very dangerous here.

Naturally, it depends on the preferences of the examiners, but a little more text than in normal presentations is definitely allowed. If the nature of your work allows, graphics, photos or flowcharts are a good way to offer some variety and to clearly present complex issues.

How to structure a successful viva presentation

Like your thesis, your viva PowerPoint presentation should follow a certain structure. It is advisable to follow the structure of your thesis. After all, you have already given it a lot of thought and made sure that everything is in a logical context.

This way you can save yourself additional work. But remember – the presentation is not about retelling your thesis word for word. Just give the most important and interesting aspects.

Follow these points to create a solid structure for any viva presentation:

1) Relevance

Your thesis dealt in depth with a particular question, a specific aspect of research. In the first part of your viva PowerPoint presentation you introduce it and explain why it is relevant. What is the benefit for academic understanding, the general public, a specific avenue? Why this question in particular?

This allows you to show your audience why you chose your topic and why they should pay attention to what you have to say. All this needs to be supported by a professional introduction. You can find tips on how to do this here .

2) Background

This is where you set out the background of your research question in more detail, i.e. the most important theories and approaches that already exist on the topic, or which prompted your question. This helps your listeners prepare for any complex interrelationships, and clarifies the basis on which you have built your work.

In this part you set out how you approached your work. Was your research qualitative or quantitative? Did you conduct interviews, analyze data, evaluate a particular body of literature? This is your chance to show your examiners how carefully you worked and explain why you chose this particular method.

4) Findings

Now to present the results of your research. Were there any surprises? If so, how did you deal with them? Are the results consistent, where did you encounter difficulties, and how did you solve them? Use this section to talk about your research in a transparent and honest way. It’s an opportunity to show that you have dealt with the topic seriously and in depth, rather than just choosing the easiest way.

5) Conclusion

At the end, summarize your work clearly and concisely, and answer the research question posed at the beginning. You can also express your personal opinion as to whether you have achieved the result you expected or whether your research has come to a surprising conclusion.

Finally, you will need a well-rounded conclusion to your viva presentation. You can read tips for the perfect presentation ending here .

Whether you have to present your sources at the end of your viva is something to discuss with your supervisor or read up in the regulations. If in doubt, however, it’s better to be on the safe side with a list of sources.

Viva presentation: example

Since every viva is different, there is no one example of a great PowerPoint viva presentation. In our blog you will find numerous examples of how a well-structured and appealing PowerPoint presentation can look. For example, here . These should serve as a guide; it’s important to adapt the presentation to your personal requirements and your audience.

Make sure your narrative is clear and consistent throughout your presentation (as it was in your thesis).  It might be a good idea to ask your supervisor to show you good viva presentation example from previous years or to give you tips on where you should focus your attention.

General tips for a successful presentation

Almost there! You’ve created and double-checked your PowerPoint viva presentation and you’re feeling confident about your research work. For many people, though, creating the content is the easy bit; it’s the thought of speaking in front of others that terrifies them. It’s just a fact that in order to defend a thesis, you first have to be attacked .

1. Be prepared for critical questions and comments. Think through what possible aspects of your work might attract criticism, and prepare your rebuttals in advance. It helps to let friends or family read your work and ask questions.

2. The same friends and family can be amazingly useful as a practice audience. Deliver your presentation a few times in front of others and in a relaxed environment. This will help you feel more confident when it comes time for your viva presentation. Your trial audience may discover inconsistencies you’d missed, and can often provide valuable feedback on how your slides look, your speaking style or your body language.

3. Body language is very important when you’re giving your presentation; it can affect your persuasiveness. Stand upright (or sit if you need to). A small amount of movement can emphasize your engagement with the subject, but try not to look restless.  Getting your words across means you mustn’t turn your face away from the audience. Small gestures can underline your words, but too much fidgeting will look like nerves. 

Practising giving your presentation will soon get your body language expressing ease and confidence. To learn how to best prepare for a presentation, read our blog article on the right body language

4. Many people tend to speak far too quickly in presentations, probably to get the whole thing over as quickly as possible. While this is understandable, it means the audience misses half your words! Try to breathe calmly and speak evenly.

Time can seem to speed up when you’re in a stressful situation, so speak more slowly than you think right. And taking a proper breath in between phrases will help ground you.  You can find tips on how to prepare your speaking voice for your viva presentation in this blog post .

Your test audience can give you very good feedback here. When you practice your presentation, use a stopwatch to make sure that you stay within the given limits. Once you know that you won’t overrun even when speaking calmly, you can avoid the temptation to rush during the official presentation.

5. Pro tip: Do you have to give your viva presentation online? If so, some things will of course be different, starting with what program you use to stream your presentation. You can find out what options you have in this blog post . Click here to read more about what to pay attention to when giving an online presentation.

While knowing what you want to say is important, DON’T try to learn your entire presentation by heart. Even if you somehow did manage to, it would end up sounding artificial and you could be easily thrown off track if you miss a word or someone interrupts with a question. The best strategy is to memorize a few key points and speak freely.

Take a deep breath before you start and remember that you have no reason to be nervous. Nobody knows your work as well as you do; you’ve done all the research and can consider yourself an expert on your topic.

And if a mistake does happen, here are some tips on how to react to it with confidence.

If the examiners seem receptive to it, a little small talk before you start can help you to relax. And once you start, remember that you’ve practiced hard and are well prepared to give an impressive viva presentation. Good luck!

What is a viva? PhD viva, viva voce, viva process and more

If you are a PhD candidate and preparing to take the biggest step in your academic journey, you might be overwhelmed by the thought of your impending viva voce or the oral defense of your thesis.

Worry not, we are here to demystify the process and provide you with actionable tips to successfully navigate this crucial academic milestone.

Here, we will guide you through the viva process, shed light on the perspective of your examiners, and help you understand how to prepare for this pivotal examination. 

Whether you’re just beginning to wrap your head around what a viva entails or are already deep in the trenches of preparation, this blog is designed to offer you comprehensive, step-by-step guidance.

By understanding the process, expectations, and preparing effectively, you can walk into your viva with confidence, ready to defend your thesis and demonstrate your deep understanding of your research area.

What is a PhD viva or viva voce?

A PhD viva or viva voce is an oral examination where you defend your thesis in front of internal examiner(s) from your institution and/or external examiner(s) from another institution specializing in your subject area.

There may be up to 5 people on your viva panel. 

They are testing your knowledge and thought processed to be admitted into the degree.

Typically lasting for an hour and a half to two hours, the viva is a conversation between experts, giving you the chance to elaborate and clarify your research.

Preparation for the viva can involve ongoing conversations, with supervisors and focused development after thesis submission.

As the viva voce derives from the Latin for ‘living voice,’ let your passion for your research come alive in your defense.

As nerve-wracking as it might be, remember to relax and use this opportunity to share your contribution to your field. 

Supervisors will (or at least should) conduct mock vivas to help you prepare for questions and build confidence. Ask for a mock viva if one is not offered by your supervisor. 

During the viva, your supervisor may be present as a silent observer, ensuring examination conduct.

Outcomes of a viva range from:

• passing without corrections,
• passing with minor or major corrections,
• or not passing at all.

Examiners won’t necessarily spot all mistakes, but they read your work thoroughly, engage in a comprehensive discussion, and submit independent reports before the viva.

Understand what’s expected of you in your viva (Examiner point of view)

From an examiner’s point of view, in your viva, you are expected to confidently explain and defend your thesis.

You should be well-prepared, recognizing that examiners will carefully read your work and may identify minor mistakes.

Keep in mind that examiners may not know your thesis as well as you, so be prepared to clarify and elaborate on your research. 

They may ask some really simple and basic questions of you – particularly early on in your thesis defense.

It is essential to demonstrate your understanding of the topic and address any questions posed by the examiners.

You may have the option to include your supervisor or other supportive figures from your institution during the viva for moral support and to witness the examination’s conduct.

Understand that examiners typically work independently and exchange reports just before the viva, so be ready to engage in a comprehensive discussion about your work.

Focus on showcasing your:

• research abilities, and
• significance of your thesis

during the viva.

How to prepare for your viva exam

To prepare for a PhD viva, follow these actionable steps:

1. Familiarize yourself with your examiner’s and supervisor’s work (4-5 days): Know their research interests, potential biases, and recent publications, and consider how they might relate to your thesis.

2. Understand your thesis deeply (5-6 days): Be able to explain your research question/hypothesis, aims, theoretical framework, methods, and key results concisely. Review all the papers you discussed or mentioned in your thesis, noting their relevance to your work. Address any weaknesses in your analysis, and justify your study’s merit to earn a PhD.

3. Practice summarizing your thesis: Prepare a 200-word summary of each chapter and a 2-minute explanation of your whole thesis. Be ready to clarify your work in one or two sentences.

4. Anticipate general questions : Examples include summarizing your thesis, stating your research question or hypothesis, and discussing your main results. Prepare answers for potential questions from both a general and discipline-specific context.

5. Conduct mock vivas with your supervisor: Simulate the viva experience to get comfortable with the format, build confidence, and receive feedback on your performance.

6. Review general questions and answers (last 1-2 days): Brush up on your prepared responses and make any necessary final adjustments.

Remember, most PhD students pass their viva, so focus on preparing and confidently discussing your research.

Things to keep in mind during your viva – top tips

Here are the top tips to keep in mind during your viva:

1. Ask for clarifications if a question is unclear. Be polite and ensure you understand the question before attempting to answer it.   2. Don’t interrupt the examiner while they are asking a question. Give them time to finish, as it shows respect and allows you to fully comprehend the inquiry.

3. Be honest if you don’t know the answer to a question. Prepare a polite response for unexpected questions you cannot answer.

4. Maintain confidence without arrogance. Display a level of nervousness that reflects your dedication to the process, but avoid overconfidence or disrespect.

5. Keep your answers concise and structured. Use a clear format when providing your response, such as breaking it down into key points.

6. Speak at a moderate pace. Avoid talking too fast or too slow, as it can be distracting for the listeners. Practice controlling your speech rate during your preparations.

7. Give yourself plenty of time before the defense to prepare and relax. You should be in the right state of mind for your viva.

8. Be familiar with the protocols, format, and panel of your viva. Attend other thesis defenses, read your institution’s guidelines, and research the background of the examiners on your panel.

By following these tips, you can enter your viva well-prepared and have a successful defense. Enjoy the experience and demonstrate the hard work you have put into your research.

Wrapping up – thesis viva

Concluding our comprehensive guide on the viva process for PhD students, the final thought we leave you with is this: your PhD viva, or viva voce, is an opportunity to defend your research, a unique chance to demonstrate your motivation, strengths, and even your limitations as a researcher.

It’s important to understand the viva definition in its entirety: a viva voce is an oral test undertaken in front of a panel of examiners.

This panel usually includes one internal examiner from your institution and one external examiner from another. It may also include other experts depending on policies and practices.

Preparation is key when you get to the viva stage.

To that end, arranging a mock viva with your supervisor could help you anticipate the types of questions you’ll be asked. This practice could enable you to put your best foot forward during the real deal.

Don’t be surprised if the viva examination lasts anywhere between one and four hours.

You may be asked to elaborate on your PhD thesis, defend your field of study’s claims, discuss its strengths and weaknesses, and suggest future research opportunities. Your response to the assessment task should be in-depth and thoughtful.

Under the current COVID-19 conditions, many students are having their viva over Zoom or Skype.

In these cases, it’s important to arrange your setting to minimise distractions. Feel free to ask for clarification if the audio cuts out or you miss a question.

In preparation for your viva, review the academic profiles of your panel members, anticipate questions they might ask, and keep a copy of your thesis at hand.

Also, remember that while it’s important to provide an in-depth response, a concise explanation is ideal to avoid going on a tangent. If you’re asked about any weaknesses or limitations in your work, be honest and thoughtful in your response, highlighting your problem-solving skills as a researcher.

You’ve worked hard to reach this stage; now it’s your chance to shine! Best of luck!

Preparing For Your Dissertation Defense

13 Key Questions To Expect In The Viva Voce

By: Derek Jansen (MBA) & David Phair (PhD) . Reviewed By: Dr Eunice Rautenbach | June 2021

Preparing for your dissertation or thesis defense (also called a “viva voce”) is a formidable task . All your hard work over the years leads you to this one point, and you’ll need to defend yourself against some of the most experienced researchers you’ve encountered so far.

It’s natural to feel a little nervous.

In this post, we’ll cover some of the most important questions you should be able to answer in your viva voce, whether it’s for a Masters or PhD degree. Naturally, they might not arise in exactly the same form (some may not come up at all), but if you can answer these questions well, it means you’re in a good position to tackle your oral defense.

Viva Voce Prep: 13 Essential Questions

• What is your study about and why did you choose to research this in particular?
• How did your research questions evolve during the research process?
• How did you decide on which sources to include in your literature review?
• How did you design your study and why did you take this approach?
• How generalisable and valid are the findings?
• What were the main shortcomings and limitations created by your research design?
• How did your findings relate to the existing literature?
• What were your key findings in relation to the research questions?
• Were there any findings that surprised you?
• What biases may exist in your research?
• How can your findings be put into practice?
• How has your research contributed to current thinking in the field?
• If you could redo your research, how would you alter your approach?

#1: What is your study about and why did you choose to research this in particular?

This question, a classic party starter, is pretty straightforward.

What the dissertation or thesis committee is assessing here is your ability to clearly articulate your research aims, objectives and research questions in a concise manner. Concise is the keyword here – you need to clearly explain your research topic without rambling on for a half-hour. Don’t feel the need to go into the weeds here – you’ll have many opportunities to unpack the details later on.

In the second half of the question, they’re looking for a brief explanation of the justification of your research. In other words, why was this particular set of research aims, objectives and questions worth addressing? To address this question well in your oral defense, you need to make it clear what gap existed within the research and why that gap was worth filling.

#2: How did your research questions evolve during the research process?

Good research generally follows a long and winding path . It’s seldom a straight line (unless you got really lucky). What they’re assessing here is your ability to follow that path and let the research process unfold.

Specifically, they’ll want to hear about the impact that the literature review process had on you in terms of shaping the research aims, objectives and research questions . For example, you may have started with a certain set of aims, but then as you immersed yourself in the literature, you may have changed direction. Similarly, your initial fieldwork findings may have turned out some unexpected data that drove you to adjust or expand on your initial research questions.

Long story short – a good defense involves clearly describing your research journey , including all the twists and turns. Adjusting your direction based on findings in the literature or the fieldwork shows that you’re responsive , which is essential for high-quality research.

#3: How did you decide on which sources to include in your literature review?

A comprehensive literature review is the foundation of any high-quality piece of research. With this question, your dissertation or thesis committee are trying to assess which quality criteria and approach you used to select the sources for your literature review.

Typically, good research draws on both the seminal work in the respective field and more recent sources . In other words, a combination of the older landmark studies and pivotal work, along with up-to-date sources that build on to those older studies. This combination ensures that the study has a rock-solid foundation but is not out of date.

So, make sure that your study draws on a mix of both the “classics” and new kids on the block, and take note of any major evolutions in the literature that you can use as an example when asked this question in your viva voce.

#4: How did you design your study and why did you take this approach?

This is a classic methodological question that you can almost certainly expect in some or other shape.

What they’re looking for here is a clear articulation of the research design and methodology, as well as a strong justification of each choice . So, you need to be able to walk through each methodological choice and clearly explain both what you did and why you did it. The why is particularly important – you need to be able to justify each choice you made by clearly linking your design back to your research aims, objectives and research questions, while also taking into account practical constraints.

To ensure you cover every base, check out our research methodology vlog post , as well as our post covering the Research Onion .

#5: How generalizable and valid are the findings?

This question is aimed at specifically digging into your understanding of the sample and how that relates to the population, as well as potential validity issues in your methodology.

To answer question this well, you’ll need to critically assess your sample and findings and consider if they truly apply to the entire population, as well as whether they assessed what they set out to. Note that there are two components here – generalizability and validity . Generalizability is about how well the sample represents the population. Validity is about how accurately you’ve measured what you intended to measure .

To ace this part of your dissertation defense, make sure that you’re very familiar with the concepts of generalizability , validity and reliability , and how these apply to your research. Remember, you don’t need to achieve perfection – you just need to be aware of the strengths and weaknesses of your research (and how the weaknesses could be improved upon).

Need a helping hand?

#6: What were the main shortcomings and limitations created by your research design?

This question picks up where the last one left off.

As I mentioned, it’s perfectly natural that your research will have shortcomings and limitations as a result of your chosen design and methodology. No piece of research is flawless. Therefore, a good dissertation defense is not about arguing that your work is perfect, but rather it’s about clearly articulating the strengths and weaknesses of your approach.

To address this question well, you need to think critically about all of the potential weaknesses your design may have, as well as potential responses to these (which could be adopted in future research) to ensure you’re well prepared for this question. For a list of common methodological limitations, check out our video about research limitations here .

#7: How did your findings relate to the existing literature?

This common dissertation defense question links directly to your discussion chapter , where you would have presented and discussed the findings in relation to your literature review.

What your dissertation or thesis committee is assessing here is your ability to compare your study’s findings to the findings of existing research . Specifically, you need to discuss which findings aligned with existing research and which findings did not. For those findings that contrasted against existing research, you should also explain what you believe to be the reasons for this.

As with many questions in a viva voce, it’s both the what and the why that matter here. So, you need to think deeply about what the underlying reasons may be for both the similarities and differences between your findings and those of similar studies.

#8: What were your key findings in relation to the research questions?

This question is similar to the last one in that it too focuses on your research findings. However, here the focus is specifically on the findings that directly relate to your research questions (as opposed to findings in general).

So, a good way to prepare for this question is to step back and revisit your research questions . Ask yourself the following:

• What exactly were you asking in those questions, and what did your research uncover concerning them?
• Which questions were well answered by your study and which ones were lacking?
• Why were they lacking and what more could be done to address this in future research?

Conquering this part dissertation defense requires that you focus squarely on the research questions. Your study will have provided many findings (hopefully!), and not all of these will link directly to the research questions. Therefore, you need to clear your mind of all of the fascinating side paths your study may have lead you down and regain a clear focus on the research questions .

#9: Were there any findings that surprised you?

This question is two-pronged.

First, you should discuss the surprising findings that were directly related to the original research questions . Going into your research, you likely had some expectations in terms of what you would find, so this is your opportunity to discuss the outcomes that emerged as contrary to what you initially expected. You’ll also want to think about what the reasons for these contrasts may be.

Second, you should discuss the findings that weren’t directly related to the research questions, but that emerged from the data set . You may have a few or you may have none – although generally there are a handful of interesting musings that you can glean from the data set. Again, make sure you can articulate why you find these interesting and what it means for future research in the area.

What the committee is looking for in this type of question is your ability to interpret the findings holistically and comprehensively , and to respond to unexpected data. So, take the time to zoom out and reflect on your findings thoroughly.

#10: What biases may exist in your research?

Biases… we all have them.

For this question, you’ll need to think about potential biases in your research , in the data itself but also in your interpretation of the data. With this question, your committee is assessing whether you have considered your own potential biases and the biases inherent in your analysis approach (i.e. your methodology). So, think carefully about these research biases and be ready to explain how these may exist in your study.

In an oral defense, this question is often followed up with a question on how the biases were mitigated or could be mitigated in future research. So, give some thought not just to what biases may exist, but also the mitigation measures (in your own study and for future research).

#11: How can your findings be put into practice?

Another classic question in the typical viva voce.

With this question, your committee is assessing your ability to bring your findings back down to earth and demonstrate their practical value and application. Importantly, this question is not about the contribution to academia or the overall field of research (we’ll get to that next) – it is specifically asking about how this newly created knowledge can be used in the real world.

Naturally, the actionability of your findings will vary depending on the nature of your research topic. Some studies will produce many action points and some won’t. If you’re researching marketing strategies within an industry, for example, you should be able to make some very specific recommendations for marketing practitioners in that industry.

To help you flesh out points for this question, look back at your original justification for the research (i.e. in your introduction and literature review chapters). What were the driving forces that led you to research your specific topic? That justification should help you identify ways in which your findings can be put into practice.

#12: How has your research contributed to current thinking in the field?

While the previous question was aimed at practical contribution, this question is aimed at theoretical contribution . In other words, what is the significance of your study within the current body of research? How does it fit into the existing research and what does it add to it?

This question is often asked by a field specialist and is used to assess whether you’re able to place your findings into the research field to critically convey what your research contributed. This argument needs to be well justified – in other words, you can’t just discuss what your research contributed, you need to also back each proposition up with a strong why .

To answer this question well, you need to humbly consider the quality and impact of your work and to be realistic in your response. You don’t want to come across as arrogant (“my work is groundbreaking”), nor do you want to undersell the impact of your work. So, it’s important to strike the right balance between realistic and pessimistic .

This question also opens the door to questions about potential future research . So, think about what future research opportunities your study has created and which of these you feel are of the highest priority.

#13: If you could redo your research, how would you alter your approach?

This question is often used to wrap up a viva voce as it brings the discussion full circle.

Here, your committee is again assessing your ability to clearly identify and articulate the limitations and shortcomings of your research, both in terms of research design and topic focus . Perhaps, in hindsight, it would have been better to use a different analysis method or data set. Perhaps the research questions should have leaned in a slightly different direction. And so on.

This question intends to assess whether you’re able to look at your work critically , assess where the weaknesses are and make recommendations for the future . This question often sets apart those who did the research purely because it was required, from those that genuinely engaged with their research. So, don’t hold back here – reflect on your entire research journey ask yourself how you’d do things differently if you were starting with a  blank canvas today.

Recap: The 13 Key Dissertation Defense Questions

To recap, here are the 13 questions you need to be ready for to ace your dissertation or thesis oral defense:

As I mentioned, this list of dissertation defense questions is certainly not exhaustive – don’t assume that we’ve covered every possible question here. However, these questions are quite likely to come up in some shape or form in a typical dissertation or thesis defense, whether it’s for a Master’s degree, PhD or any other research degree. So, you should take the time to make sure you can answer them well.

The Oral Examination (viva) - Doctoral degrees, MSc, MLitt, MPhil by Thesis

What is a viva.

The viva (short for viva voce) is an oral examination which gives the opportunity for:

• you to defend your thesis and clarify any matters raised by your examiners
• the examiners to probe your knowledge in the field
• the examiners to assure themselves that the work presented is your own and to clarify matters of any collaboration
• the examiners to come to a definite conclusion about the outcome of the examination

Your examiners will determine if you meet the requirements for award of the research degree  for which you are a candidate.

Preparation

Talk to your supervisor and/or Academic Adviser for guidance on how to prepare for your viva.

The Quality Assurance Agency for Higher Education (QAA) has produced a series of videos to help PGR students prepare for their viva. Note that the procedures for examination at the University of Cambridge may be different to those referred to by other Higher Education Institutions featured in the videos.

You will have been told the identity of your examiners. This will normally be one examiner internal to the University of Cambridge and one external examiner, but you may have two external examiners. The Degree Committee may also appoint an Independent Chair to be present during your viva and/or additional examiner(s). Your examiners will be in touch to make arrangements for your viva .  If you have not been advised of the date for your viva within six weeks of submitting your thesis, you should contact your Degree Committee.

Location of the viva

The viva will normally take place in-person in Cambridge, but you may choose to be examined remotely by video conference. You should inform your Degree Committee of your preference when you notify them of your intention to submit/apply for appointment of examiners. Please also make your supervisor aware of your preference as it may affect the choice of available examiners.

Arrangements where you and one examiner are co-located in Cambridge, with the second examiner participating by video conference, where both examiners are co-located and you participate by video conference, or where you and the examiners are all in separate locations, are permissible provided all parties agree.

In-person oral examination:  In-person examinations may be delayed depending on the availability of the examiners as travel time will need to be factored in. Students who are overseas and returning to Cambridge for their viva should contact the International Student Office for visa advice if their student visa has expired or will be expiring soon.

Video conference oral examination: A guide to conducting vivas by video conference can be found here .

The choice of in-person or video conference viva does not constitute procedural irregularity grounds for complaint should you fail the examination.

Adjustments to the oral examination on the grounds of disability

If you wish to notify examiners of a disability or request adjustments on account of a disability for your viva (either your first year assessment or final examination), you can do this via your Degree Committee by completing and submitting the voluntary disclosure form . It is recommended you do this at least four weeks before your expected date of examination to allow time for appropriate recommendations and adjustments to be made. 

Once you have submitted the form, your Degree Committee will contact the University’s Accessibility and Disability Resource Centre (ADRC) who will advise the Degree Committee on the appropriate course of action. You may be contacted by the ADRC if additional information is required or to provide you with an offer of additional support.

The information provided on the voluntary disclosure form will be kept confidential and will not be used for any other purpose.

If you already have a Student Support Document (SSD) that includes recommendations for adjustments to the viva , and you have given permission for the SSD to be shared with the Degree Committee, you do not have to complete the voluntary disclosure form but may do so if you wish.

There is no specific dress code. You can wear whatever you feel comfortable in.

What can I take in to my viva?

You may take the following into your viva:

• A copy of your thesis (the same as that you submitted)
• plain paper or blank notebook and a pen/pencil for taking notes or sketching ideas
• a presentation in the form specified by your Examiners – your Examiners will advise you in advance if a presentation is required
• any other provision that is agreed in advance with the Degree Committee as a reasonable adjustment for disability.

What happens at the viva?

• It is carried out between yourself and the two examiners and is conducted in English
• It may include an Independent Chairperson if the Degree Committee requires this
• There is no set duration, but a viva will normally last between 90 minutes and three hours
• You may be required to do a presentation - please check with your Department whether this is the case. If you are required to give a presentation, you should be informed at least two weeks in advance of the viva
• The viva cannot be recorded
• Your supervisor cannot attend the viva

Your Department should advise on any department-specific conventions or procedures.

Possible outcomes of the viva

The possible outcomes are:

• Conditional approval - pass without correction (but for doctoral degrees subject to submission of hardbound and electronic copies of the thesis ); or pass, subject to minor or major corrections 
• Revision and resubmission of the work for a fresh examination
• [Doctoral examination only] Revision and resubmission of the work for a fresh examination or acceptance of the MSc/MLitt without further examination (but possibly subject to corrections)
• [Doctoral examination only] Not to be allowed to revise the thesis, but offered the MSc/MLitt without further revision or examination (but possibly subject to corrections)
• [Doctoral examination only] Revision and resubmission of the thesis for examination for the MSc/MLitt degree
• Outright failure

Notification of the result of the viva

Your examiners are asked not to give any direct indication of the likely outcome of the examination as the official result of examination can be confirmed only by the Postgraduate Committee or by Student Registry acting on its behalf (or the Degree Committee for the MPhil by Thesis). The Degree Committee will forward their decision to the Student Registry who will notify you of the outcome and email your reports to you, copying in your Supervisor.

Here are my detailed advanced tips on how to pass viva voce during your PhD studies. These viva tips will help you remain confident throughout your presentation

What is a Viva Voce?

A PhD scholar does not consider completing the thesis paper an accomplishment because they are still required to go through the viva voce process.

Although there are countries such as Australia that do not require one to do so, others like the United States necessitate the scholar to go through the process.

A viva voce is an oral examination whereby the researcher is required to stand before a panel of examiners to defend their dissertation .

This is why it is essential for the scholar to ensure that they have clearly mastered the field and the chosen topic by conducting the research on their own.

During the viva voce, the evaluators are at liberty to ask whatever question they feel is related to the topic and the candidate has the obligation of answering the question satisfactorily.

Simply put, a viva voce is an oral presentation that is aimed at proving that the researcher commands knowledge on the topic and has gained knowledge on the field of study.

When is PhD Viva voce examination conducted during PhD

A PhD viva voce examination is the last thing that comes in the PhD process whereby the researcher is required to present themselves before evaluators and answer any questions thrown at them regarding the thesis.

That said, the viva voce comes after the candidate has submitted their thesis to the faculty. Upon receiving the research paper, the evaluators may require the scholar to present themselves in person and required to exhibit what they have learned during the Ph.D. process.

Therefore, a viva voce comes after submission of the thesis and before the candidate earns the doctorate title.

How long is the PhD Viva Voce Presentation with example

Many Ph.D. candidates are concerned by the duration that a viva voce takes and we would like to point out that it all depends on how prepared one is for the same.

Traditionally, a viva voce is supposed to take ninety minutes with no hassles. However, it boils down to the examiners’ decision and if they feel that the time is not enough, then they can extend the process up to three hours.

The purpose of the process is to evaluate how much knowledge one has acquired during the Ph.D. and whether they are capable of answering questions related to their topic.

Therefore, it is true to state that the length of the viva voce will depend on the examiners. If the candidate does not satisfy their expectations, they are bound to ask more questions thus the process I likely to take more time

How many examiners will site in PhD Viva Examination

Many scholars are concerned about with the viva voce since it makes almost all candidates nervous as is the case of any situation where one has to stand before viva examiners and defend their work.

When one is deemed qualified to do a Ph.D., they are assigned a supervisor who ensures that the Ph.D. process is not marred by challenges through offering advice to the scholar.

The examiners are mostly two all of which should come from the university’s faculty. To ensure that the evaluation process is effective, they are mostly chosen from the same field as the candidate. Although it is not a must, there are occasions where the examining body may also comprise of external members.

This implies that the minimum number of examiners is two but they can be more according to the university’s decision.

Viva Preparation Questions

• What is the new thing that one feels to read your PhD dissertation?
• How do you prove this experiment can change the way others think?
• Explain the validity of your proposition with some examples.
• Give one strong why should we accept your thesis to be authoritative.
• What influenced you to make your thesis stand out from others

Why is PhD Viva Presentation conducted

A thesis is nothing short of a research paper which means that the scholar is expected to have taken their time to conduct thorough research using advanced techniques.

The main reason why a viva voce is conducted is to give the researcher an opportunity to defend their work before they are graded whether they meet qualifications or not.

The first thing that the scholar should know is that they should be able to defend their thesis which means that they should be aware of everything that is in the research paper. The reason for this is because one can never know what the examiners will ask and from which section of the thesis they will derive their questions.

It is essential that the scholar must ensure that they are prepared adequately by going through their thesis and ensure that they are able to answer any question arising from the same.

There are candidates who may be tempted to have other people write their thesis and although it may be perfect, the viva voce reveals the truth depending on whether they can defend the thesis or not.

Be what you are in your PhD Viva Exam

According to many candidates, the viva voce is an impeachment whereby they feel like they are grilled, but in a real sense, it is designed to prove to themselves and others whether they are in a situation to defend their title as a doctor of philosophy in their field.

It is therefore important for the candidate to ensure that they do not fall prey to brown nosing. They should not direct their efforts to sweet-talk the examiners by trying to impress them. Instead, the scholar is advised to play their role and prove to the evaluators that they are capable of defending what they have written in the thesis.

It is recommended that the scholar should be calm, relaxed and confident in their thesis and have the courage to stand before the examiners and express themselves.

The candidate should recognize the importance of the thesis and this is partly the reason why they have the responsibility of choosing their own topic and doing the research.

Never give one-word answers during Viva Voce viva exam

A viva voce must not be confused with a multiple choice questionnaire thus the researcher must appreciate that it is intended to diminish curiosity.

This cannot be achieved by giving one-word answers because the scholar is required to explain themselves as reflected in the thesis. Important to note is that a person’s standing or view on a certain view cannot be explained in a short statement.

The reason for this is because when one is asked a question during the viva voce, they are expected to state their position on the matter. The statement is not enough because it only triggers more questions.

Therefore, it is necessary that the scholar must support their claim by giving explanations as to why they support their arguments. In fact, the primary purpose of the viva voce is to ensure that the scholar can defend what they advocate for thus they should be in a position to give explanations and proof of what they are saying.

Be confident throughout the session (not over confident) during doctoral viva

According to human nature, there are people that find it easy to stand before others and air their view but the viva voce does not recognize that. It is essential that the scholar must be in a position to present themselves and stand for what they have presented to the faculty and the world.

At this level of learning, it is expected that the scholar must be confident enough to ensure that they can speak in front of a crowd leave alone two or three examiners. Confidence is a virtue that must be acquired by all scholars to ensure that they can stand before others and teach them or address key concerns that affect society.

However, the candidate must take caution not to be overconfident and the main reason for this is that too much confidence is interpreted as arrogance.

The bad thing about this is that the examiners are likely to get the wrong impression about the scholar. This is true because among the virtues that a Ph.D. teaches the candidate is patience and respect for others.

Do not show that you are afraid of Viva Voce of dissertation

The human mind is designed in such a manner that it controls the entire body and command activities that the individual will like and those that they will not.

One of the reasons why most scholars fail the viva voce process is that they tend to develop a negative attitude towards the same even before they go through the process.

It is essential that the scholar must be confident and not only outwardly but also inwardly. We recommend the scholar to ensure that they take all necessary measures to ensure that they do not exhibit fear in front of the examiners.

It is understandable that anyone is capable of nervousness while in front of a panel of examiners. However, we recommend that the scholar must pay attention to two things to boost their confidence. The first element is that they should prepare adequately for the process.

The second is that they should develop a positive attitude towards the viva voce. Adhering to these two advises is bound to increase the scholar’s confidence in themselves and their thesis.

My top Viva advice is to practice before one month

In the scholar’s life, before they take the Ph.D. course, it is true to say that they have gone through many examinations and passed. It is not automatic to pass an examination and it requires a lot of dedication and sacrifice.

Although there are individuals that may be tempted to take a shortcut, there is only one recipe to passing. All examinations require a lot of preparation and a viva voce is not exceptional.

This implies that the scholar must take their time to prepare for the viva voce beforehand. It is recommended that the candidate should take at least one month to prepare themselves.

It may seem like a difficult thing to do but we remind the scholar that they have a supervisor who has knowledge about the viva voce and they can offer useful advice that can make the process easy for the candidate.

Dress proper and be neat and formal during thesis viva preparation

The short description of a viva voce is that it is an oral presentation and therefore it means that there must be physical appearance.

Appearance has a powerful effect in that it creates a lasting impression on the examiners and therefore, the way that one presents themselves before the evaluators automatically make them judge the candidate’s character. The scholar wants the evaluators to be on their side and therefore the first thing that should pop in the scholar’s mind is creating a good impression.

It is essential because it may affect the examiners’ judgment which implies that a good impression is likely to yield good results while a bad impression is likely to yield bad results.

It is crucial that the scholar must dress formally for the viva voce and they should be neat. The proper dressing makes the scholar look responsible and in a position to defend their thesis.

Read your thesis once and thrice and prepare sample PhD viva answers

The viva voce is an oral presentation of the thesis and therefore it is necessary that the scholar must ensure that they have a proper understanding of their thesis before they engage with the examiners.

It is purposeful for the scholar to have 100% knowledge of the thesis even though it is common to forget some points. To avoid mistakes arising from being unable to answer some examiners’ questions, we recommend the scholar to make a point of revising the thesis before and after submitting to the faculty.

Some scholars might consider reading the thesis twice sufficient but this is not the case.

Others may be overconfident and feel that they do not have to read the thesis again but this is usually a recipe to disaster. It is our recommendation that the scholar reads through the thesis at least three times to ensure that they are familiar with all the points discussed within.

Learn how to start your opening speech of PhD Viva

It may sound tricky to summarize a paper comprising of at least 50,000 words in as little as five minutes but it is possible and the scholar should practice doing so.

Essentially, the examiners expect the scholar to have mastered their thesis and therefore they should be able to point out the problem surrounding the topic as well as the causes and recommended solution briefly.

At the onset of the viva voce, the scholar must be in a position to introduce the dissertation to the examiners briefly. This involves presenting an overview of the research paper.

Among the different sections of the thesis is the abstract section which was explained as a summary of the research paper. While preparing for the viva voce, the candidate is advised to consider the abstract and use it as a guideline for the oral presentation.

Listen to what your examiner is asking clearly

The easiest way to fail in any examination is answering the wrong questions or failing to address what the examiner requires.

It is mandatory for the candidate to pay attention to what the examiner is asking and carefully analyze points that they require from the candidate.

By doing so, the scholar is in a position to give the right feedback with reference to the thesis. It means that it is important for the candidate to concentrate during the viva voce and they should ensure that they are not distracted by anything else. 100% concentration is a requirement for the viva voce process if the candidate is going to answer questions satisfactorily.

Do not argue under any circumstance (just defend)

It should be noted that a viva voce is not a form of a debate where two parties are engaged in arguing. The candidate should note that the examiners are already professors and they are not there to engage in a battle of wits.

What they require from the candidate is proof that they have learned during the research and that they are in a position to demonstrate that they command knowledge in their specific fields.

That said, rather than argue, the candidate must ensure that the presentation is based on defending the thesis and shows the validity of the scholar’s standing regarding the points presented in the dissertation.

Pass- short corrections-resubmit- Fail after Ph.D. Viva defense

After the oral presentation, the examiners make a point of presenting their results to the candidate which point out areas that were sufficiently answered and those that were not.

The candidate should look into areas where they gave wrong answers and make a point of researching and making the necessary changes.

The correct answers should be passed to the examiners. The candidate must ensure that the correct answers are written as briefly as possible.

Do not write stuff on your hands or hold slip while defending viva thesis

During the oral presentation, it is necessary that the scholar avoids writing points in their hands or slip. It is so because it acts as a way of showing that the scholar has not prepared sufficiently for the viva voce.

In addition, it creates the impression that the researcher is not fully aware of the content in the thesis. Using written points give the impression of someone who is presenting a speech that has been written for them.

The candidate does not want the examiners feeling that they have not done the research for themselves as this would automatically lead to a fail.

How to do viva presentation with an impressive eye contact

A good presentation is one that the candidate commands presence before the examiners as it shows that they are confident with their work. It also shows that the scholar has worked hard for the thesis and they have nothing to fear regarding the viva voce.

One way of showing the examiners that the candidate is prepared and has dedicated themselves to the research is by making constant eye contact with the examiners.

The researcher should also be careful not to give too much attention to one examiner and instead they should keep eye contact with all the researchers during the whole viva voce.

Plan some expected questions and your answers

Whichever situation that one finds that they are required to make a presentation before a panel or a group of people, the first thing that the person does is to prepare adequately.

It is useful for the candidate to expect some questions that are likely to be asked during the presentation and therefore the scholar should make a list of some of them and work on possible answers.

Although one cannot fully predict the type of questions, it is important for the candidate to conduct a research of previous viva voce that have been done on the same field. Also, the scholar must consult the supervisor who may have useful advice.

Be ready to explain the drawbacks of your thesis cleverly

There is no perfect research and all of them are liable to limitations which the candidate must make a point of acknowledging before they are asked.

The scholar must be prepared to mention the drawbacks and explain why they arise. Merely stating the drawbacks is not enough since it will only make the examiners curios and therefore the candidate must defend the thesis wit-fully taking care to show that the limitations could not be avoided.

Challenges encountered during the thesis should be noted since they might be helpful in explaining the limitations or drawbacks.

Make rehearsals before two days of your viva voce

It has been noted that the scholar must ensure that they are fully prepared for the viva voce before meeting the examiners. Apart from reading through the thesis at least three times, the candidate should ensure that they prepare for the presentation prior to the scheduled day of the meeting.

If possible, the candidate is advised to look for friends and prepare a mock viva voce whereby they act as the examiners and ask questions that the candidate feel could potentially be asked.

This process should be done at least two days before the presentation. A rehearsal is important because it assists the candidate to engage how much they know pertaining to their thesis and some areas that may not have been given adequate attention can be addressed.

Never say “I don’t know” Somehow defend PhD viva (Be it wrong its ok)

A research paper consists of a lot of content and it may not be possible to remember everything that is contained in the same. It is common for the examiners to ask questions that the candidate has not prepared themselves to answer but this should not deter them from answering.

In case the candidate encounters such questions, they should not hastily state that they do not have the answer. Instead, the candidate should take their time and reflect on the thesis and analyze the connection between the question and the thesis.

It is understandable if the answer is not correct but at least the candidate should try to answer the question.

Prepare some positive statements of English to use them during presentation of your viva

One way of preparing for the viva voce is to ensure that one has answers to the examiner’s questions. The main areas of concern are the main points and how they are relevant to the topic.

A presentation must have statements that can be defended at all times since they help the scholar to show the importance of the thesis to the community. Such statements must be positive in nature and exhibit backing up of the thesis.

They should be prepared in English since it is the universal language that is applicable to almost all job specifications in the job market.

How to present PhD viva presentation positively

Positive statements are one way of the researcher showing that they have confidence in themselves and the thesis. Throughout the viva voce, the candidate must ensure that they have a positive attitude which is essential because it draws the examiners on their side.

A positive attitude makes it possible to answer questions easily and there is a likelihood that the examiners may not ask questions that put the candidate in bad situations. It enables the scholar to be motivated and therefore they are able to answer questions freely without feeling tense.

Be audible and do not look shy during thesis viva presentation

It is understandable that some people may have difficulty in standing before people and speaking their minds. However, the scholar is advised to remember that this is their dissertation and the presentation is among the stakeholders that determine whether one will pass or fail.

To counter shyness, the candidate is advised to prepare themselves adequately before the viva voce process. It is important because it boosts the candidate’s moral and level of motivation.

A scholar that is prepared becomes confident in themselves and they also develop a positive attitude which makes it easier to face the examiners and answer any question hurled at them without fear.

If you have had any experience with public speaking skills, you can do this task very easily. But unfortunately, you might have been lazy not to learn these skills when your English Teacher taught you during your school days. You need to give your count now while doing your Ph.D. viva. These skills are very necessary to get through these oral sessions. The way you speak is what matters seriously for the examiners or the reviewers.

Once you are through enough to make it, you can become successful. This way you can become a lot more confident and you will pass this viva without any doubt. While presenting do remember that you have to make some preparation for the last two months. This preparation is the only backbone for your viva. If you do not prepare beforehand you will face trouble while presenting your Ph.D. viva oral

When you keep this in mind, there are some other tips, I want to give here. See how PhD candidates do their viva online. If you go on to youtube you will get many videos in real time. Learn from them how they are able to present during such stressful sessions. I suggest you watch at least one video about Ph.D. viva or any other sessions with respect to Viva. This will surely give you fuller knowledge and viva presentations presentation tips about viva

When you want to give Ph.D. viva, try to show respect who are around you. They may be irritating sometimes to face. But you must never lose temper if someone asks you an inappropriate question. These type of unrelated questions are very common while giving your Ph.D. viva oral examination.

Master all the techniques on how to face audience and PhD supervisor during your viva voce. The way you speak, the way you behave, the way you respond, the way you manage, the way you present. All such skills must be learned before going to viva session.

You cannot make yourself a bluff in front of others for simple questions. So in order to avoid this, you must take your viva seriously and make sufficient preparation.

Never lose heart rather increase your active participation in the viva. If someone corrects you, accept it humbly and proceed to the next defending minutes. So Ph.D. viva is not a big problem if you follow all these suggestions throughout the reading on how to do Ph.D. Viva Voce.phd viva tips

How to prepare for your viva: 8 useful tips

Agata frymus.

21 June 2018

1: Read your thesis

No matter how many times you have done it before, reading your thesis a week or two before the viva is always a good idea. Although I have proofread my thesis several times before the submission, this time my focus shifted : rather than looking for spelling mistakes, typos and missing references, I concentrated on the quality of my argument. What are the research questions posed in each chapter? What are the main findings? And, most importantly, how could this work be improved?

To make sure I actively engaged with the ideas developed by the thesis, I highlighted some parts of the texts and made notes. I also produced a rather short document in which I summarised each of my eight chapters (as well as the introduction and conclusion) according to the following criteria:

• Key arguments and findings
• Methodology and scholarship used

Thinking about my work in those fairly broad terms helped me to understand how to explain it to those who might not be familiar with the specificity of my subject. Additionally, it enabled me to reflect on the potential shortcomings of the research I conducted, which proved instructive during the viva discussion. Although this might sound like a laborious process, let me assure you that it was not. I have spent about a week (if not less) reading the thesis and making notes, and it wasn’t even the only thing I was occupied by (which brings me to my next point).

2: Don’t over prepare 

How long is one supposed to spend on viva preparation? Given the importance of the examination, you might be tempted to think that the longer the better, right? Well…not exactly. After all, everyone I talked to (see point 4) admitted they regretted spending too much time on the prep. Even though I have heard stories of PhDs devoting a month – or more –  solely to viva-related study, I decided to be sensible and spend no longer than two weeks on preparations. Two weeks in which my mind won’t be occupied by anything else but the viva. When I shared my plan with my supervisor, he deemed it extravagant. ‘How long do you need to read something?’, he asked, and I’m glad he did. The thing is, as a PhD student you have spent at least three years researching your topic. At this point, you are the expert in your chosen field; it is probably fair to assume that you do not need weeks and weeks of additional study. You have already done the groundwork. Be confident in your knowledge.

3: Think about the potential questions

One of the best things you can do to maximize your chances of a confident viva performance is to consider the potential viva questions and the way in which you could approach them. There are plenty of websites that provide you with sample discussion points that are likely to be raised by your examiners and most of them are broad enough to be applicable to your thesis, regardless of the specificity of your topic. I used these and these as starting points. Considering the questions in advance will add to your confidence as you will be less likely to be taken by surprise. If you do, however, end up being mildly shocked by the question asked by the examiner, do not panic. It is perfectly fine to take some time to gather your thoughts, or even write main points down on a piece of paper if the question is more complex.

Some of the questions I have been asked at the beginning of my viva included:

• Why have you chosen these particular stars as your case studies? What sparked your interest in them?
• How did you go about conducting your research?
• What are the differences between researching print copies of fan magazines and the online/ digitised versions?

Most of the questions, however, related to specific paragraphs and passages from my thesis. The worksheet I produced as part of the prep process (see point 1), enabled me to anticipate criticism and answer such questions without feeling like I’m losing my ground.

You don’t necessarily need to write your answers down either: one of my friends told me they went on long walks during which their pondered the potential discussion points and subsequent responses.

4: Talk to people who have passed their viva

The views expressed by those who have successfully passed their viva seemed to share a similar tone: it’s nothing to worry about, it’s nowhere as scary as you think it will be, it will be fine, and so on. This, in itself, is quite reassuring. Talking to friends and colleagues about their experiences , however, might give you some interesting insights too. I really dreaded questions relating to the critical choices I made in the process of compiling my thesis: why have I chosen this star/ fan magazine, and not a different one? How should I explain something that was, in many respects, not only an analytical, but also a personal choice? What I understood as a result of those conversations was that simple, honest answers (‘these specific fan magazines are easily available in the digital form and are searchable’/ ‘Pola Negri has something of a cult status in Poland, where I come from’) are often the best ones.

5: Arrange a mock viva

It’s a truism, I know, but confidence is key. Even if you have conducted high quality research, your points will not come across particularly strong if you mumble or are not able to express yourself clearly. Before presenting any paper or a lecture I always, always make sure I practice my presentation in front of friends, family members or anyone who is willing to listen. This gives me a better understanding of how I will behave under pressure , because a certain amount of stress is always there, no matter if I present in front of my boyfriend or an academic audience of 30.

Therefore, I think it is crucial to run a mock viva as part of one’s preparation. It will not always increase your confidence at the actual thing, but it will also give you some useful feedback regarding your answers and performance. For example, my mock viva – which I organised with a fellow PhD student and my supervisor as examiners – made me realise that I need to be more explicit when talking about my methodology, starting with more general terms. Although I have explained the importance of post-colonialism, critical race studies and feminism in structuring my approach, I failed to mention gender and film studies, which are much broader and probably more important categories. Secondly, the feedback I received as the result of this exercise boosted my confidence. Despite the fact my heart was racing/ my hands were shaking/ I felt very anxious, neither of my mock examiners noticed any of it. At the end, the mock examination turned out to be much more stressful than the real one!

Alternatively, you can arrange a mock viva with friends, or even video record your answers on your phone. Whilst watching yourself might sound painful, it could show you that you never come across as bad as you think you do. It’s scientifically proven.

6: Know your examiners

I find interviews/ examinations/ any form of discussion less threatening if I have met the person doing the questioning. This might not work as effectively for everyone, but somehow meeting one of the examiners in person beforehand – even if that meant simply knowing their tone of voice and general demeanour – made me feel much more confident in myself. If you feel the same way, I would suggest you try to meet your examiners in an informal setting. They will probably be fine with a coffee sometime before the viva, as long as you explain your reasoning and stay away from discussing your PhD and the viva itself.

My viva took place on Tuesday. I spent the last couple of days leading too it doing absolutely nothing in terms of preparation, assuming, rather correctly, that it will achieve little more than stress me out.  I went to see a friend over the weekend (we made vegan burritos) and stayed at another friends’ house the night before, watching First Dates. I know that people deal with stress differently, but for me, preparing earlier and then taking my mind off the viva was the best thing I could do. Have a bath/ go on a hike/ exercise the night before; whatever works.

8: And finally… Enjoy it!

The viva is a rare opportunity to discuss your research with two people who not only have read your thesis in its entirety, but who are also likely to be specialists in your field . Make the most of the opportunity it offers, and enjoy yourself as you do; after all, you produced a valuable piece of work and there is no reason why you should not feel happy about it.

Proven Strategies to Help You Deliver an Impeccable PhD Viva Voce

Handing in your PhD thesis after months of hard work may well be the most gratifying moment in your doctoral journey. While you may be happy and relieved to have completed this important milestone, there is one last challenge to be met before you can earn your PhD degree – that of delivering an impactful PhD viva voce. The viva voce is an oral examination where doctoral candidates are invited to defend their PhD research. The objective of the viva is to establish your competence as a researcher and to confirm that the research thesis submitted is your own work 1

The format for the viva may differ based on the country or institution. Some countries, like the UK, have a private viva with a panel of at least two examiners, while others hold the PhD final viva in a public setting, with students having to present their research and answer questions from a panel of examiners and the audience. 2 

Having to defend your research in the presence of accomplished experts in your field can be very intimidating. In this article, we share proven strategies to help you prepare for and deliver an impeccable PhD viva voce.

Tips to help you prepare for your PhD viva voce

• Know what is expected of you: Check your institution’s policies to understand how the PhD final viva will be structured. Specifically, ask about the number and role of the examiners, whether there will be an independent chair, and whether your supervisor will participate. You should also confirm the format of your PhD viva voce – public, private, or online. Some institutions also offer students training on or opportunities to practice your viva, which is something you shouldn’t miss.
• Learn more about the examiners: You will be presenting to senior academics with unique backgrounds and views, so it is important to learn more about their professional profiles and published work, especially if their research relates to your thesis. This will give you an idea of where they are coming from and the kind of questions they may ask.
• Draw up a list of possible questions: It is always a good idea to try and anticipate the kinds of questions that may be asked of you. Most will be based on your thesis, so may seem easy but take time to practice vocalizing the answers. Some of the common topics for discussion are:
• What is the main research question you hoped to address?
• How do you think your thesis contributes to your field of research?
• Would you change anything if you had to start your research again?
• What, in your opinion, are the strengths and inadequacies of your thesis?
• Why did you pursue a PhD and what are your plans for the future?
• How would you proceed from here if research funds were not an issue?
• Revisit and revise your thesis thoroughly: It is always a good idea to carry a copy of your thesis; ensure the pagination matches what the examiners have so that you can easily refer to it and call out critical results or data as you explain your research. Highlighting key text can help you answer questions more quickly and confidently. It is also important to have a good understanding of your field of study, including where your work fits in and how it can be used to develop future research.
• Plan toward your PhD viva voce presentation: Once you get a date for your PhD final viva, plan backwards so you have enough time to review your work. Usually, a viva may take roughly two hours, so pace yourself, arrive well ahead of time and ensure that you are carrying everything you need for the day. If your PhD viva voce is online, make sure you have a strong internet connection and are seated in the right environment. Keeping a positive attitude, taking time to relax and ensuring you get enough sleep the day before the viva will help you stay alert.

Simple advice to keep in mind when delivering your PhD viva voce

Here are a few things to keep in mind during your oral examination.

• Prepare for the icebreaker: The ice-breaker is a 5-10 minute introduction about you and your work. It helps set the tone for the rest of the viva, so do take time to think about how you can make it impactful.
• Start strong and stay committed. Respond with precise, detailed answers that demonstrate your knowledge and thought process. Vague, non-committal answers could raise red flags for examiners and lead to negative reviews. Take time to understand the question and answer to the point. Be prepared to provide supporting data from your research if required.
• Request clarity on ambiguous queries: Don’t hesitate to ask for clarifications if you don’t understand a question. Some questions can be tricky and require a deep understanding not just on your subject matter but also on interdisciplinary aspects related to your research. If you are unsure about the answer, be honest and admit it.
• Express your opinions and ask questions: Think of the PhD viva voce as an open and honest dialog where you discuss your research, especially in the context of other work in the field. Feel free to ask questions or politely disagree if you do not agree with certain points. Use examples from your work to explain your views.
• Avoid being overconfident, defensive, or long-winded: While it’s important to know your research, it’s just as important to know how to act during the PhD viva voce. Staying humble, listening carefully, and keeping an open-mind is always helpful.
• Don’t worry about long silences: During the PhD final viva you may find yourself worrying about periods of silence from the examiners. Rest assured, this does not mean that you are not doing well, so be patient and stay calm.

The Viva Process

Passing the viva: beginning the viva process.

The success guide for doctoral students explain that the viva is an opportunity for you to discuss your findings, as well as to demonstrate you have become an independent researcher: 

“Your viva is a chance to show your in-depth knowledge of your subject area and discuss the important research findings that you have made - whether they are positive or negative. A doctoral degree is a training process. Your examiners are there to establish you have achieved this training and that the work contained in your thesis is your own. They want to see that during the course of your degree you have started to become an independent well-rounded researcher who is making a valuable contribution to the research community”. 

There is more information on the  Progression and Feedback pages. 

Expand the questions below to learn more. 

Viva Process

What is the viva process.

During the viva you will discuss with examiners your research: why and how you developed it, what are the main and innovative findings, what is the impact of your research.

The viva is an open book exam, you will have a copy of your thesis with you to use it during your discussion and refer to specific parts (College regulations, paragraph 6.6, p. 8: A candidate for the PhD or MPhil degree is required to bring to the viva voce examination a copy of their thesis paginated in the same way as the copies submitted electronically to the College).

What paperwork needs to be completed for the viva to be arranged?

You will need to complete the “Nomination of examiners and entry form” at least 4 months before the submission of your thesis, as explained in the Student records and data webpage:  

You should aim to submit your examination entry forms at least four months before you would like to submit your thesis, or four months before your final submission deadline. 

This means submitting your forms no later than 44 months after your start date if you are a full-time student, or 88 months after your start date if you are a part-time student. 

As indicated in the Student records and data webpage:  

Complete Section I and forward this form to your supervisor(s). Please ensure the form is completed fully by referring to the guidelines at bottom of the form. 

• Your supervisor will then complete Section II, including nominating two examiners for your viva examination following the Procedure for appointment of examiners for research degrees (PDF, 196 kb). Once your supervisor has completed Section II they should forward it to the Director of Postgraduate Studies for your Department for approval, and they will return it to us. 
• The examination entry has a life of 18 months, during which the thesis can be submitted for examination. After 18 months, the entry will be cancelled, and another entry form will need to be completed. 

More information available on the  Examination Entry Forms  web page. 

How are examiners chosen for the viva?

Internal and external examiners are nominated in the section II of the “Nomination of examiners and entry form” (see question above).  

As indicated in the Procedure for appointment of examiners for research degrees (paragraphs 4 and 5, pp. 1-2): 

According to the same document, exclusion criteria are (paragraphs 7, 8, 9 and 15, p. 2-3): 

There is more information available on the Procedure for Appointment of Examiners for Research Degrees (MPhil, PhD, MD(Res), EngD) document (PDF, 196 kb).

Who arranges where the viva examination takes place?

The viva is typically organised by your supervisor or a staff member of your department: 

Once you have submitted your thesis, the Registry will ensure that copies are provided to your examiners, in advance of your viva examination. 

Your supervisor, or another member of staff in your department/division, will be responsible for organising the viva and making all the necessary arrangements. 

There is more information available on the Student records and data webpage – Vivas section .

Should I prepare a presentation for the viva?

A formal presentation with slides is not usually required. However, since one of the first questions might be “explain me in 5 minutes your research project”, you are suggested to prepare it (similar to an elevator pitch, with no slides). During this short presentation you can refer to a specific section of your thesis as support to your explanation.  

You can practice your speech at the workshop provided by the Graduate School:  “Advanced presentations ”.  

Can I request a break during the viva?

Yes, breaks are allowed according to the College regulations (Appendix 4, paragraph 16, p. 9): 

There are no set requirements about the conduct of viva voce examinations, nor about their duration, but they should be conducted in such a way that the candidate has adequate opportunity, encouragement and time to explain his/her research and to defend the thesis. It is recommended that, during a long viva voce examination, examiners should allow short break(s) at appropriate point(s) (see also paragraph 44). 

What is the role of my supervisor during the viva?

According to the College regulations (paragraph 8.1.8, p. 10):  

The supervisor shall not be invited, unless the candidate indicates otherwise at the point of entry to the examination, to attend the viva voce examination of his/her PhD or MPhil candidate. If invited to attend as an observer, the supervisor does not have the right to participate in the examination of the candidate but may contribute if invited to do so by the examiners. Otherwise the viva voce examination shall be held in private. In exceptional circumstances and also in the early stages of a joint or collaborative degree the Provost may appoint an independent observer to attend a candidate’s viva. 

What are the possible outcomes?

Outcomes are defined in the College regulations (paragraphs 8.2.3, pp. 10-11). Appendix 4 (paragraphs 23 and 24, p. 4) contains a summary of it:  

Paragraph 24: Examiners should not consider option (e) unless they have first considered and rejected as inapplicable the preceding options; and should not consider option (f) unless they have previously considered and rejected as inapplicable all the previous options (see also paragraphs 28 and 29). 

¹ The examiners may require the candidate to make specified minor amendments to their satisfaction within three months. The amendments required should be set out clearly, normally in writing, and normally be provided within two weeks of the viva voce examination. The examiners (or one of their number nominated by them) may arrange directly with the candidate for the amendments to be made. The examiners may, however, wish this to be arranged through the College Registry. In either case the examiners should complete the Report form (see paras 25 and 32) and return it, with the required enclosures, to the College Registry normally within two weeks of the oral. 

What are the assessment criteria?

Criteria are defined in the College regulations (paragraph 5.1, pp. 4-5): 

How can I handle my nerves before and during the viva?

The Success guide for Doctoral students contains tips to overcome stress and relax before and during the viva. 

Before the viva:  

Anticipate questions - Ask your supervisor to provide you with a list of questions that they would anticipate may be asked. Identify areas that you are uncertain about and discuss further with your supervisor if you have concerns about what you could be questioned on. 

Mock viva to practice - You may find your supervisor or department will automatically organise a mock viva. If not, ask your supervisor if they will conduct a mock viva with you, perhaps including another member of the research team who is familiar with your research work and could ask you relevant questions.  

You can have the opportunity to practice a mock viva during the Finish Up and Move On (FUMO) course , organised by the Graduate School. 

Review your material - Make sure you have not missed anything along the way. If there is anything you are unsure of, make time to focus on that area again. Mark up key parts of your thesis. Remember you are allowed to take a copy of your thesis into the examination. You can refer to it if needed, such as when discussing key figures and tables in relation to the data that you have generated. Some time may have passed since you submitted your thesis, so make sure you are up to date with relevant publications published after your thesis submission. If you don't you may find that your examiners are more up to date on relevant published research findings than you. 

Keep calm - When re-reading your thesis and revising for your viva do not let yourself get too stressed. Allow yourself plenty of time to prepare for the examination. Do not leave things until the last minute - especially not the night before the viva.  

Allow yourself time to relax, eat properly, and sleep. You will function better in your viva if you are not tired, hungry and grumpy - and you'll make a better impression on your examiners (there is more information on the  Progression and Feedback page).

During the viva, important things to remember are:  

Just as when delivering any other presentation, remember to breathe, pause between sentences and engage with your examiners. Regular eye contact is key. 

If you do not understand the question, ask the examiner to repeat it. If you do not know the answer to a question, just be honest and say so. 

When answering questions, take a moment to think before you speak. That way you will ensure you give a detailed but concise answer and will avoid waffling in an unfocused manner (there is more information on the  Progression and Feedback page).

How do i prepare for a phd viva, phd viva presentation, phd viva questions.

It is a matter and pride great amount of pride to get done with your Ph.D. degree. A great number of efforts goes into making it happen. But preparing dissertations, thesis and getting it reviewed by the panel is no less than a herculean task. Even though you are done with preparing your thesis, yet the journey continues. There exists one big task to complete or to say a bridge to cross before finally getting your thesis approved and being conferred with the doctorate. This essential part during the doctorate or Ph.D. program is the viva. After you have prepared your thesis, the next step is submission to the panel wherein it will be reviewed and the student will be intellectually tested for their knowledge that they have put into the process.

Passing through this hurdle will ensure your doctorate degree which requires little more labor and a lot of sharp wits. So, before heading on to discuss how one can manage or survive the rig-ours of Ph.D. viva let’s take a sneak peek through the actualities of why the viva is conducted and later move towards tips and tricks to ease the entire process:

Why is a Viva required?

Viva is an oral examination wherein students are tested on their thinking caliber in front of a big panel of experts. The primary purpose of a viva is to understand how much does the student know about the topic and to understand their level of contribution. Well, doesn’t that make you read through your work and prepare well for the viva before getting through the actual process?

What does Viva include?

As any other viva session, a Ph.D. viva includes a lot of question and answers with you on the latter side of the panel. The thesis prepared by you will be thoroughly reviewed by experts right from the topic to the format. The formal purpose is to have a direct discussion with the students to test their knowledge of the subject.

Ph.D. being an important degree and thesis being the most essential aspect of the course. Thence one cannot deny its level of crucial and importance. Viva also includes Ph.D. viva presentation wherein the student will be required to prepare a PowerPoint presentation surrounding the topic. The PowerPoint presentation will include all the minute points and details most importantly those points which you wish to highlight in your study, mentioned in a gist. This not only makes the entire process less cumbersome or writing, preparing and presenting viva but also throws out light about the student’s knowledge of the topic.

Summarizing of the topic

The Ph.D. viva begins with the student asked to summarize the entire topic in a gist. The student must thus prepare themselves in advance to speak about your topic, the reason for choosing the topic, what does it convey. Additionally, it is recommended to read the entire thesis well before the presentation and viva, jotting down important points which can be put forth as questions. The summary will be the first ground to set your impression on the invigilator. The topics may also lead to debates, wherein your caliber and expertise in the subject will be tested further.

When preparing for Viva:

Be well abreast with the university’s terms and policies. Each and every institution and university have their own set of terms and conditions. Therefore, it is imperative to primarily read through the conditions and accordingly prepare yourself for the big day. You could also try to find about the panel that would be conducting the viva and get an understanding from peers about the kind of questions they pose and what to expect during the viva, which will prove to be cherry on the cake for your preparation.

• Go through your thesis

Go through your theses, but now not as a student but as a third person. This will help you see through the prism of your thesis and help you gauge any loopholes and whether the research is up-to-date. Moreover, never underestimate the time spent by the examiners in reading through your thesis. And thus, this calls for you to be an equal expert who can handle the questions tactfully.

Along with reading through your thesis, check whether there have been any recent papers which are published in the particular topic same as yours and if so, ensure to read through them to be abreast with the latest happenings.

• Hit the bull’s eye

During a Ph.D. viva, there are usually two examiners who would be present during the process. One who is an external expert from the field, who is not usually from your university and the other an internal one who is a subject expert associated with your field. Your onus is to win the minds of both. It is usually the external examiner who will be shooting the questions. Thus, being pretty updated with the subject knowledge, reading about the contributors who are related to your topic in some way is the best way out for winning the doctorate.

• Prepare your answers

This is an important aspect of the viva and it all depends on how you defend your research.From this perspective, it is necessary to defend your point of view and claims, explaining your contribution and knowledge of the topic. Remember that no project is ever perfect, however, letting the examiner know you have contributed your best to the project is all the more important. For this, you can kick-start with anticipating some of the most sought questions and probable ones which you consider will be asked during the viva. Primarily looking for those which are most asked during a Ph.D. viva will ease your task to a large extent. Mostly the questions will be related to your literature review and conceptual points.

• Practice the technique of answering

Well, you are not going to get a chance for reading your answers from your laptop verbatim in front of the examiner. However, being well prepared like knowing the answers like the back of your hand is the most important aspect. Articulate your answers and try to present yourself an answer in the tone you would be using for answering the examiner.

• Take a printed copy of your thesis at the time of viva

It is always better to have an extra copy of your thesis present with you at the time of viva. In this copy, mark the important points and highlight them which you think might be useful at the time of viva. This will surely leave an impression on the examiner about your commitment to and involvement in the topic.

Now coming to what to do during a viva:

• First impression matters

The first few minutes of introduction is all that can create an impression. Therefore,,keep a calm demeanor with no pinch of nervousness (though it is bound to exist). You will be getting a total of 15 minutes to articulate your knowledge to the examiner regarding the project. You must hence prepare well for your answers which showcases your knowledge of the topic, thinking-process and more importantly your confidence.

Avoid short and non-specific answers, this can turn the whole viva upside down.Thus, ensure you break the ice of silence and march ahead in the journey of achieving the Ph.D. degree and adding the prefix of Dr. to your name.

• Do not think negative

Often examiners do not render comments to the students. This gets students into a pickle wherein they consider the answers to be either wrong or not so impressive to the examiners. Most often the institutional policy prohibits giving comments and sometimes the examiner notes it in the thesis remark.

• Be ready for a healthy debate

A presentation or viva might not always be a smooth ride. There might be moments of debates that would require you to showcase your prowess. So don’t miss the opportunity, answer each question tactfully. The student here must know when to be more tactful, conceptual and when to apply a friendly tone.

• When in doubt better to get it clarified

No one is a wizard and during the viva, there might be moments due to nervousness and a constant hit of questions when you need to look through your thesis for reference. Thus, herein you can ask your examiner for some time to write it down and during the time conceptualize your answer.

• No time bar

Be well prepared and know that your viva might go on for one to 3 hours or even more. So accordingly, be well prepared with your answers and focus on explaining and expressing your contribution to the topic in a precise and concise manner.

While it might seem stressful, a Ph.D. viva is quite easy if you have a good understanding of the topic and confidence in yourself.

So running through the whole points:

• Be confident
• Read through the thesis
• Mark important points

Be tactful with your answers to sail through the viva smoothly.

Tips and strategies to prepare for your oral viva voce presentation

How to present an effective and successful viva voce, how to structure and organize a research paper.

Table of Contents

What is a viva voce?

Viva voce is a Latin word that translates most often as “through word of mouth.” It is an oral examination in academic circles during which you defend your research.

Following the defense, the thesis is debated in a small circle. Naturally, the examining professors will be there, but they may be joined by research assistants, representatives of the appropriate department, or even other students.

The aim of this defense is to demonstrate to the examiners your familiarity with your study subject, your ability to absorb and apply what you have learnt. In effect, it demonstrates if you’re well equipped to engage in intellectual debate.

In theory, the viva will not determine an entire grade, but it may tip the scales if you are on the cusp. However, it has the benefit of resolving any ambiguities, assuaging any concerns your examiners may well have, and demonstrating that you stand by your study.

The crucial point is thorough preparation

Months, if not years, of diligent labor later, the thesis is completed, the last formatting errors fixed, the bibliography carefully reviewed one more time, and hurrah, it is complete! After hours spent hunched over a desk, night shifts, and unending discipline, it is time to rejoice! And then you are invited to the viva.

The good news is that you have already completed the most of the preparation. That was the purpose of the extensive study you conducted to develop your thesis. You are already a specialist on your subject; all you need to do now is communicate it properly and calmly to your examiners. That is why it makes no sense to make preparations for your viva until you have completed your thesis and addressed all of your own questions.

Your supervisor should be aware of what to anticipate – and the viva’s goal is to communicate your findings. Some individuals just hand in their dissertation with great relief and then forget about it for a time. This is not an issue, however when the viva is coming, you need to really refresh your memory on the subject. S right your dissertation a few times to refresh your memory on your findings and methodology, and you have already accomplished a significant portion of the work required for your viva!

Organization of the viva voce

You should carefully review your institution’s examination rules to determine what will be expected of you during your viva. How long must the talk be? Is there any information on the kind of presentation, who will be present, and the structure of the post-presentation discussion group? Research has shown that knowing precisely what to anticipate substantially reduces anxiety. This is an opportunity that you should seize.

Additionally, consider what you would want to wear on the day and if you would like to create a handout.

When there are no specific guidelines, the following are some pointers:

In terms of attire, you should be led by the topic and the manner in which your supervisor dresses. If they consistently wear suits, you may infer they value formal attire. In general, strive for a tidy look and attire that is neither too casual nor too dressy.

Even though it is not expressly necessary, a handout may sometimes be beneficial. It demonstrates to the examiners that you have considered their convenience and makes the framework of your presentation simpler to follow. It may also have an effect on the following discussion, since examiners may use your handouts as a guide for their questions.

Viva Slide show presentation – technical aspects

PowerPoint is the most often used format for viva presentations. Before you begin working on the material, it is critical to familiarize yourself by how PowerPoint works.

In terms of the PowerPoint presentation itself, it is critical to avoid unnecessary transitions, overly colored slides, and foreign typefaces. This is a professional presentation, and the slides should reflect that. Unnecessary and distracting items will detract from the gravity of your arguments. Utilize a consistent font style and a neutral (ideally white) backdrop color.

The basic guideline for these kind of presentations is: Keep Things Simple. Text-heavy slides irritate people and divert attention away from the essential points. While it is ideal to utilize as little language and as few important points as possible, it is also critical to properly record your accomplishments while presenting in a viva. Allowing for interpretation may be very hazardous in this case. Naturally, this depends on the examiners’ tastes, but a bit more text than is often included in presentations is absolutely acceptable. If your job requires it, graphics, photographs, or flowcharts are an excellent method to add diversity and effectively explain complicated problems.

Additionally, it is essential to verify that all technical equipment will function properly on-site on the day. Ascertain that you understand what to do if anything goes wrong, and create as many plan Bs as possible!

How to prepare your viva opening speech

A viva, or PhD thesis defence, typically starts with an opening speech by the PhD candidate. This opening speech can be prepared in advance. How? By following six simple steps that take you from checking university requirements, to structuring and practising your viva opening speech.

What is a viva opening speech?

A viva opening speech is a short presentation of the PhD thesis by the PhD candidate. It typically lasts between 10 and 30 minutes and kicks off the PhD defence during which the candidate has to answer questions from the examiners.

Questions from examiners are relatively unpredictable. A viva opening speech, however, can be prepared and practised in advance! Therefore, it constitutes a major part of getting reading for a PhD thesis defence.

Step 1: Check the requirements for your viva opening speech

Therefore, the first step to preparing a viva opening speech should always be to find out the specific regulations of your university.

Step 2: Define the audience for your viva opening speech

Once you are aware of your university’s regulation concerning viva opening speeches, it is smart to think a bit more about the target audience of your speech.

The target audience for your viva opening speech will influence the level of detail in your presentation, the complexity of the information, and the language and terminology you will use.

Step 3: Develop key messages for your viva opening speech

Now it is time to brainstorm about the content of your viva opening speech! One harsh truth is that you simply cannot include everything. Summarising the work of 3, 4 or more years in a few minutes is incredibly challenging. You have to be selective. You have to summarise, abstract and prioritise.

The key messages for your viva opening speech should be in line with the nature of your PhD thesis. For those who have read your PhD thesis in advance, the content of your viva opening speech should not come as a surprise.

Step 4: Structure your viva opening speech

Common ways to structure viva presentations are around the table of contents of the PhD thesis, around key findings, key arguments, or around case studies.

Step 5: Create visual support for your viva opening speech

As with regular presentations, avoid too much text on slides. Instead, make strategic use of images, photographs, figures or diagrams to develop your storyline and bring your points across.

Step 6: Practice your viva opening speech

You should practice your viva opening speech up to the point that you can present freely, without reading from your notes. However, don’t learn the whole speech by heart. It is always noticeable if someone just recites text, and it will make you sound like a robot.

What’s a Viva (Viva Voce)?

As I stood outside, knowing my examiners were on the other side of that door, I was trembling. I had worked incredibly hard on my PhD and had spent years perfecting my language, all leading up to this one moment: my viva voce interview. As I waited, patiently, to begin my defence, the door opened and the committee chair said, “we are ready for you now”. I walked through the door, took a deep breath, and never looked back.

A viva voce examination, widely known as the viva, is an oral examination at the culmination of your PhD. It is comprised of a committee of both internal and external examiners who look through your work and, essentially, decide whether you pass or fail your PhD. It is an interview and there are a number of different ways that a viva can be conducted. In some cases, the viva is open to the public, which means that anyone who is interested can attend. In other cases, they are closed, which means that it is just you and a panel of examiners.

In either case, the examiners generally include internal reviewers (someone in your department who has interests in your subject area but who has not helped you with the PhD) and external reviewers (usually 2-4 people who have expertise in your discipline, but who do not teach/work at the university that you are affiliated with).

A viva voce interview usually lasts between 1-3 hours, and consists of a variety of questions related to the PhD you have recently submitted. All of the examiners will have read your PhD in its entirety prior to the beginning of the viva, and each will have compiled a list of questions. It is your job to answer these questions satisfactorily in order to pass the viva.

In this post, we are going to describe some of the most common things to consider and to remember when preparing for a PhD viva.

How to prepare for the interview

Preparing for a viva interview is a lot like preparing for a job interview. While you cannot possibly imagine every question that others might ask of you, you can certainly practice so that you put your best foot forward right from the start.

Identify the weaknesses in your PhD

Let’s face it: no one has the perfect research protocol. There are always limitations. These limitations are a perfectly acceptable part of the process, but as the researcher, it is your job to explain why you chose to conduct your study using the methodology that you did.

Usually, you can ask your supervisor(s) to help you with this. They can be a very useful resource. They might also have suggestions about what questions the examiners are likely to ask.

In addition to the imperfections, it is important to be able to justify your approach. So, if you chose to undertake a questionnaire, why was this the preferable method over other approaches? Try not to solely rely on the current circumstances (e.g. because of COVID-19 might be a possible answer, but is there a better one?). Try to think about all the strengths of your research protocol and use this information to justify your choices.

What to wear

While you might not think that clothing is an important piece to the viva, it is something that you certainly should consider. Wear something that is professional, but comfortable. This is typically a collared shirt for men at a minimum, though a suit jacket and tie are also pretty common. For women, wear a skirt or trousers, and a sweater, blouse, or suit jacket.

In all cases, wear professional – but comfortable – shoes. There is nothing worse than feeling a blister emerging as you are trying to focus on your talk! Different countries have different standards, but typically you should wear something similar to what you might wear to a job interview.

Things to remember

It is very likely that you will get a list of who your examiners will be prior to going into the viva interview. This information can be really valuable. As a first step, go and look at the publications that each of these members has produced. By reading their most recent publications, you will gain insight into what they find interesting and what they do not.

What’s more, if you have referenced any of their work in your PhD, you might be able to mention this in the viva to demonstrate that you are knowledgeable and have aligned your work with other excellent scholars (like your examiners). A little bit of flattery is always a good thing (but do not go overboard).

What questions are they going to ask?

Justifying your arguments.

It is important to think about your project. It is likely that the first question they will ask you is: Can you summarise your thesis? Try and have an answer ready that takes less than three minutes to explain and uses common language that someone who does not understand your field will be able to comprehend (i.e. keep it simple).

Justifying what you left out

As noted above, no research protocol is perfect. Further, once you have collected the data, you will likely have a lot to say. Not all of the data you collected will have ended up in your final thesis. You had to decide what to keep and what to leave out. Your examiners might want to know what you left out (and why).

Usually with these types of questions you can draw their attention back to your research questions and then tell them that the other data fell outside of the scope of the research project, but that it might be worthwhile examining in a future project.

Questioning your contribution to research

Why was your research important or worthwhile? It is important to consider what motivated you to pursue your project in the first place. What was the gap that you saw in the current research framework that needed to be filled?

Your answer does not have to be some epic achievement (though it can be). Instead, think about what the problem was and how you contributed to it.

Discussing areas for future development

Your PhD might be done, but where are you going next? What are your plans for the future? Even if your plans are to run as far as you can from the next possible research project, it is worthwhile coming up with a statement about how your research could be further developed (even if you, personally, have no interest in developing it further). You have probably made these suggestions in your actual PhD thesis, so this is just an opportunity to provide a bit more detail about how this might actually proceed.

Tips and tricks to succeed in the viva

You are likely going to know people who have participated in the viva process before, and therefore, using them as experts can be a good opportunity for practice. Now, despite saying this, people often like to exaggerate what happened during their viva voce exam, so if the person you are talking to decides to describe a stressful and uncomfortable situation, maybe try to find other, more supportive, colleagues.

You can also create a list of practise questions that you can give to a friend, colleague, or family member so that you can practise how you will respond. Even if the person who is asking a question is not an expert on your topic, they will usually be able to determine whether your answer is overly detailed and repetitive (bad) or succinctly concise and organised (good). The more you practise, the more comfortable you will get with the idea of explaining your research to strangers, which is essentially what happens in a viva voce exam.

Listen carefully to the questions being asked

There are a couple of significant places where a candidate can go wrong in a viva voce exam, and failing to answer the question asked is one of those place. First, if an examiner poses a question, do not try to jump in or talk over them. Let them ask their question, in full, before you start on your response (even if you think that you know what they will ask).

Once the examiner has asked their question, take a breath and a moment to compose your thoughts. The second mistake that candidates often make is to go off track to a tangent that is irrelevant to the question. By taking that moment to compose your thoughts, you will be able to make sure that your answer provides a clear and appropriate response to whatever has been asked.

Focus on the positives

In thinking about the questions that you might be asked, it is often human nature to dwell on the negatives; to try and justify away the negative elements of your study. You could have had a larger sample, incorporated another research method, or undertaken a more comprehensive statistical analysis of your data. You could have focused on a different theme or provided more details on a certain area of interest.

By the time you get to the viva, none of these things really matter – the study is finished, and your PhD has been submitted, read, and reviewed. So if you are asked a question where you could potentially answer in a positive way, choose that as your option. The examiners do not need to hear about what you could have done (unless they explicitly ask, which is possible). The examiners want to know why you chose the route that you did.

Let’s say, as an example, that you conducted interviews in your research study. Instead of telling the examiners why you could have also employed a questionnaire, tell them about the many ways that interviews offered you the opportunity to obtain comprehensive data that you would not have received from questionnaires. Tell the examiners how the detailed data from the interviews allowed you to delve into themes of interest and ask follow up questions in areas that you did not understand. Remain positive.

Smile (and breathe)

It is only human to be nervous going into your viva voce examination; there is a lot of pressure associated with this step in the PhD process. The examiners will know that you are nervous. If they are experienced, they will have seen many students that have been in your position. If they are new to viva exams, then they will likely remember how it feels to be a candidate. Good communication is key here.

Remember that these people are humans, too. Although they are, in a way, the gatekeeper to your success, that doesn’t make them monsters. Appeal to their good nature. Be friendly and smile, but also don’t try and hide your nerves, if you find that makes you feel awkward.

Lastly, take deep breaths. This might sound obvious, but our breath can really help to control our adrenalin levels, which when pumping, can wreak havoc with our normal behaviour. If you forget to breathe, you may, for example, stumble over your words or forget your train of thought. Take nice, deep breaths regularly, especially when the examiners are talking!

The more you practise, the more comfortable you will get with the idea of explaining your research to strangers, which is essentially what happens in a viva voce exam.

Final thoughts

When I left my viva, my committee made me sit in the hallway to await their decision. There are really four options at this point: 1. Pass, 2. Pass but make minor corrections, 3. Pass but make major corrections, and 4. Fail.

I remember feeling confident enough to know that I passed, but some of the questions were really hard and so I was thinking about how many corrections I was going to have to make (and how long that was going to take because I’d already spent years on this project). By this point, I felt like the hard part was over, there was nothing that I could do from this point that would change the outcome (but this did not make the waiting any easier). It was probably about ten minutes between the time I left the room and the time that they called me back but it felt like an eternity.

As the Committee Chair opened the door to call me back in, she only said two words… “Congratulations, Doctor”. I smiled, breathed a sigh of relief, and knew it was a great day.
