Common PhD Viva Questions

It can be pretty difficult knowing how to prepare for your PhD viva. Having successfully defended my own STEM PhD remotely in the last year, I want to help you to prepare! What follows are some common PhD viva questions which your examiners may ask you. Plus some additional advice based off my own PhD viva experience.

For an intro to the PhD viva including the typical structure and potential outcomes please see my introductory post:

• How to Defend a Thesis: An Introduction to the PhD Viva

How Much Do You Need to Prepare For A PhD Viva?

There is no hard and fast rule for how much you need to prepare. And unlike a written exam, there are of course no past-papers to practice on!

It may help ease your mind to think about what the purpose of a PhD viva is. Namely the purpose of the PhD viva (or defence) is to check that:

• You did the work;
• You understand the work;
• The research is up to the standard for a PhD.

For more detail see my separate post here including Imperial’s PhD viva mark scheme.

In hindsight I probably didn’t spend as much time preparing for my viva as is normal. Though I did unexpectedly move house less than a week before !

Besides reading through my thesis once in the few days leading up to it, I didn’t spend much time thinking up answers to questions or “revising” certain topics which could come up. The viva went fine, but it wouldn’t have done me any harm to have been a little better prepared.

It certainly helped that I’d managed to schedule a viva which took place less than six weeks after I submitted the thesis so it was all very fresh in my mind. If you submitted your thesis months before your viva I’d suggest spending slightly more time refreshing your memory in preparation for questions you may get asked.

In summary, I think it’s useful for all PhD students to get an idea of some potential lines of questioning for their oral exam!

Update: Keen to get prepared for your viva? I’ve put together a set of viva preparation worksheets which are available in the resource library. Click the image below for free access!

Listed below are common PhD viva questions which I’ve roughly grouped together. We’ll start with some higher-level questions about your PhD which should be quite easy and friendly, then progress through to some more technical (and potentially unfriendly!) questions.

It is worth noting that many examiners will ask for a short presentation at the start of the viva and this could eliminate some potential questions. In this list I’ve left in the main questions I’d expect for this presentation to address, such as what future work you’d recommend.

Very few of the questions are ones you’re guaranteed to get asked, but I can assure you that you’ll get asked at least some of them!

General PhD Viva Questions – usually friendly!

These ones are simply inquisitive and you don’t really have to worry about getting caught out. The examiners are simply interested in the work and want an insight from someone who has spent the last few years working on it.

• What is the most important finding from your PhD work?
• What was the motivation behind this research?
• Who is your research relevant to?
• Which aspects of your work are you publishing? Follow on: and where?
• What future work would you recommend?
• What are the limitations of your research?
• Which aspect of your work surprised you the most?
• What are the potential applications of your PhD research?

Method-Specific Questions – mostly friendly!

These questions dive a little deeper but even so shouldn’t be too much of a cause for concern. They come down to your own judgement and as long as you justify your decicisions you’ll be fine in answering them.

• Why did you do [things] a certain way?
• What were the alternatives to [this certain method]?
• Why did you test [that specific number] of samples?
• What effect did you think changing [something in your method] would have?
• What do you think you could have gained by using [another approach]?
• Why did you not use [another technique]?
• How did you deal with the ethical implications of your work?

Results & Analysis-Specific Questions – mostly friendly!

In a similar manner to the previous section about your methodology, you’ll often get some questions targeting your analysis and presentation of results.

• What is this graphical figure illustrating?
• Why was [this analytical technique] appropriate? Follow on: why did you use [this other technique]?
• Which of your results do you find the most interesting?
• How do you know that your findings are correct?

Literature Questions – may be less friendly!

This is where things may get tough if your examiners want to try and test your limits. Even so, they’ll still likely cut you some slack. If you have 100+ references it’s very possible that under the nerves of your exam you can’t remember specifics for each and every reference. Just don’t make things up. They’d rather you were honest than trying to deceive them.

• Please explain the key findings of reference number [X]
• Which papers would you say had the biggest impact on your work?
• What do you think are the biggest differences between [these two previous studies]?
• What have been the biggest advancements in the field over the last 10 years?
• Why did you not reference [this other study]?
• How does your work compliment the existing literature?
• What do you think the next big advancements will be in the field?

Highly Technical Questions – potentially very unfriendly!

These are the ones I was a bit scared of getting, but it is a PhD viva after all. Of course it should be expected that you have a solid understanding of the principles that underpin your project. Even so it can be unnerving thinking of how large the range of potential questions like this can be!

Unlike at a conference or in other settings where you may be able to brush over things you’re not 100% comfortable with, there is no hiding when your examiners need to test your knowledge. Particularly when they have hours of time at their disposal to do so!

• Explain how [a technique] works. This could be anything from sample preparation, equipment and analysis through to statistics. I’ve known people to get asked to explain things like a statistical t-test from first principles, with follow-on questions being asked with every answer to drill deeper.
• Explain [some fundamental concept, phenomenon or principle]. Just like the last question but applied to basic-sciences. I’ve known students to get asked questions such as: explain energy (to a mechanical engineer) and explain toughness (to a materials scientist). I’m sure we can all explain these concepts to a certain level but my concern was whether or not I could explain them at a deep enough level to satisfy the examiner.

With both of these types of questions there ultimately comes a point where you (or the internal examiner ) can push back and say that answering that question was not the focus of your PhD!

What Questions I Got Asked at My Own PhD Viva

I was really surprised at my own viva how few questions I actually got in general.

The viva lasted a whopping five hours (excluding a quick break) and yet almost all of the time was spent discussing improvements to my viva to help with publishing papers.

Even so, I could have done with putting a bit more time into preparing for potential questions: which was my motivation to help you by putting together this post!

The few questions I had included:

• If you were to do the project again would you do anything differently?
• Clarification of what I meant by certain sentences in my thesis .

You may be wondering if I avoided getting asked deeper questions by the examiners because I already had a relationship with them so they were satisfied with my knowledge and capabilities. But I didn’t really know the examiners! I’d met my external examiner at a conference and he had seen me present but I’d never actually met my internal examiner before.

Instead, what I think did go a long way to helping was having already had something published in a respected journal.

Nevertheless, in a way I actually walked away a little unsatisfied by the lack of questioning at my PhD viva.

It was great to get so much feedback on my thesis which has already helped to get two more papers published since the viva, but I felt like it would have been nice to feel a bit more taxed and known that I could hold my own in the exam if it came down to it.

Now looking back on the viva 10 months later, I’m just happy to have the PhD done!

My Tips for Answering Common PhD Viva Questions

• Keep calm and take your time before answering . There is no rush to answer questions. Having a sip of a drink may help provide a pause for thinking up an answer.
• Tell the truth. If you don’t know something, just say so! It’s likely the examiners will quickly be able to tell that you don’t know what you’re talking about. Plus, there is the risk that they’ll ask deeper follow-on questions which could unravel any lies.
• Try to enjoy the experience. Think of it as a discussion, rather than a police investigation. Your examiners are interested in the work and want to hear more about it!

Top 12 Potential PhD Viva Questions and How to Answer Them

Breathed a sigh of relief after submitting the PhD thesis you’ve burnt the midnight oil for? Not so soon! While submitting your thesis is a massive achievement, defending it decides whether you will receive the doctoral degree or not. Although every PhD viva examination is different, there are similarities in the types of questions asked at each. In this article, we shall discuss the most common and potential PhD viva questions and how to answer them.

Types of PhD Viva Questions

Generally, examiners prepare a series of questions for you to answer at the PhD viva voce examination. These questions are primarily based on your thesis. However, the questions asked in PhD viva examinations can be broadly grouped under four basic headings:

• General Questions
• Research Context and Methods
• Analysis and Findings
• Discussions and Conclusion/Implications

Therefore, while preparing for your PhD viva and defending your thesis , you must consider the types of questions you’re likely to be asked. This helps in practicing your answers in advance and not being baffled during the viva. Practicing how you would answer questions based on these four basic categories will take you a long way in your preparations.

Commonly Asked PhD Viva Questions and How to Answer Them

While sticking to answering the most commonly asked questions might sound simple, it is equally important to be prepared for counter questions. Furthermore, it’s easy to go off on a tangent due to nervousness. This leads to opening up other lines of enquiry from the examiners in areas you hadn’t probably expected to be questioned about.

Ideally, you aren’t expected to dictate your thesis as it is. Examiners are interested in knowing your understanding of the research, its methods, analysis and findings, conclusion and implications, etc.

Despite the differences in every PhD viva, you must be prepared to answer these common questions logically. Below are some popular PhD viva questions to prepare:

1. Tell me about yourself.

Introduce yourself and talk about your areas of interest related to research. More importantly, focus on the areas you are extremely positive about. Briefly speak about your past achievements without overwhelming the examiners and sounding boastful. Keep the introduction professional.

2. What is the reason for selecting this research question?

The response to this question is often generalized by saying that you are interested in the topic. However, examiners want to hear the specifications of your interest in the topic. You must plan your answer stating the most interesting aspect of your research and why did you choose the research question over another topic from the same or allied domain. Furthermore, cite certain instances that helped you in selecting the research topic and the particular field for your project.

3. What is the key focus of your research?

Remember that the answer to this question is not about summarizing your research. It involves talking about the area of primary focus of research. Most importantly, in order to demonstrate the viability of your research, it is essential to identify some of the key questions it addresses.

4. Did the research process go as per your plan or were there any unexpected circumstances that you had to deal with?

The purpose of this question is not only to see whether you can work as per your structured plan, but also to understand your readiness with backup plans in case of unforeseen situations. An ideal way to answer this is by clearly stating if the project went as per your predefined plan. Furthermore, be honest in mentioning if you were assisted by others in dealing with it, as it may lead to a new set of questioning from the examiners.

5. After completion of your research, which part of the process did you enjoy the most and why?

Remember that the examiners know about a PhD student’s stressful journey . Therefore, do not elaborate on the hardships that you went through during your research, unless asked otherwise. Emphasize on the aspects of the research project that you enjoyed and looked forward to every time you stepped in your laboratory. Describe how you developed interest in newer approaches to conduct research.

6. As a researcher, what change has this research brought in you?

This question demands a strong, progressive, and positive response. Remember your first day in the research laboratory and compare it to today. Identify the differences in your traits as a researcher. Mention how following, reading, and analyzing other researchers’ works have brought a positive change in you. Furthermore, address how you overcame your shortcomings as a researcher and upskilled yourself.

7. Summarize your thesis.

Be well versed with the entire project. Start by explaining why you selected the topic of your thesis and close your explanation by providing an optimum solution to the problem. You must prepare for 3 types of answers for this question. Prepare a 1-minute, 3-5 minutes, and 10-minute summary and use the correct one based on your audience at the viva.

8. What developments have you witnessed in this field since you began your doctorate? How did these developments change your research context?

Familiarize yourself with the advances in your field throughout your PhD. Mention works of researchers you have referred to while working on your project. Additionally, elaborate on how other researchers’ work influenced your research and directed you to finding results.

9. What original contribution has your thesis made to this field of study?

Answer this question by keeping in mind what was known before in published literature and what you have added as part of being awarded your PhD. Firstly, you must present a major piece of new information during your research project. Secondly, elaborate on how your research expands the existing literature. Thirdly, mention how your work is different from other researchers’ works that you referred. Finally, discuss how you developed a new product or improved an existing one.

10. How well did the study design work?

While answering this question, you must focus on how your planned methods and methodologies were executed. Furthermore, mention how you tackled difficulties in study design and concluded your research.

11. Elaborate on your main findings and how do they relate to literature in your field?

While answering this question, elaborate on how you evaluated the key findings in your research. Mention the key factors involved and the reason for choosing a particular process of evaluation. Furthermore, explain how your findings are related with the literature review of your project. Mention its significant contributions in your field of research. In addition, discuss how your research findings connect with your hypothesis as well as the conclusion of your research.

12. What is the strength and weakness of your research?

While you may want to impress the examiner by emphasizing on the strengths of your research, being aware of the weaknesses and planning a directional move to overcome them is also equally important. Hence, mention the strengths first and elaborate on how they connect with the key findings. Additionally, underline the limitations and the factors that could be transformed into strengths in future research.

• Top 40 potential questions to be asked in a PhD viva or defense

June 20, 2024 Filed under Blog , Featured , Presentations , Resources , Writing  

“Your thesis content” by errantscience.com

Students worry about their vivas. They wonder whether they need to do additional work or read textbooks and articles again. For most students, they don’t need to do all this. My advice has consistently been the following to prepare for your viva: Pick up dissertation a few days before the viva, and read through it to remind yourself of what you did and wrote. Do not fret about misspellings or other minor issues. They are inevitable, and the examiners will not be too taken aback by a few errors here and there. Then, spend time thinking.

What is important is that you think more broadly about the work that you have been doing, how it fits into your discipline, what you might have done differently in hindsight, and where you or the community could go next.

There used to be a blog called Research Essentials hosted by the Open University that had this list of 40 potential viva questions to help candidates prepare for their vivas or defenses. This list of questions is excellent preparation for your viva, and I have shared it with many of my students. This blog has since gone, but others have promoted this list of questions and not attributed it to the original author. Wanting to make this resource more widely available and ensuring the original author gets the credit, I am promoting it here. Please find this list below.

Thank you to the original author Rebecca Ferguson , then a research fellow at The Open University, now a professor.

Top 18 PhD Viva Questions | Examples

The PhD viva is an oral assessment held by a committee during the PhD defense. This evaluation involves the committee posing inquiries to the PhD candidate regarding their research work and dissertation.

This article explores the PhD viva questions, provides 18 sample questions, and offers advice on responding to them effectively.

The questions asked during a PhD viva typically come from the candidate’s original work proposal and other submitted written materials.

Types of PhD Viva Questions

Preparing and practicing your responses to questions from these four fundamental categories will significantly help in your preparation efforts.

Frequently Asked Questions for PhD Vivas and How to Answer to Them

You should be ready to answer these common questions logically, despite the differences in each PhD viva.

• What is the PhD Viva?

Written by Mark Bennett

The viva voce is the final assessment for a PhD. It is an oral examination where the student defends their research to two academic examiners. This involves answering questions about your work, typically related to the literature, methodology, your findings and the significance of your conclusions. In some countries (like the USA ) the viva is actually referred to as a 'PhD defence', because the candidate defends their thesis from these questions.

This guide explains exactly how the viva works, what to expect on the day, how to prepare and what happens afterwards.

An overview of the PhD viva

The PhD viva can seem like an intimidating process, but it actually serves a very simple purpose: proving that your research is original, that you understand its contribution to knowledge and – most importantly – that your work is your own. It's also very rare for students to fail.

Who attends a viva?

A PhD viva usually involves two examiners: one internal examiner (from your university) and one external examiner (from another university). Both should be familiar with your field and the external examiner in particular should be a recognised expert in your specific research area.

The internal examiner usually acts as the chairperson for the exam, making sure it follows your university's procedures.

Your supervisor doesn't normally attend the viva itself, but they will help you prepare for it and should be around to provide support on the day.

How long does a PhD viva take?

There is no set length for a viva voce exam, but most take between one and three hours .

A longer viva doesn't necessarily indicate any problems with your thesis: it may simply be that the examiners are enjoying the discussion. Equally, a shorter viva may just mean that your examiners are satisfied with the thesis and your responses to their questions.

Why is the viva necessary?

The most basic function of the viva is to prove that your work is original (i.e. not plagiarised). This is especially important because the criteria for a doctorate is to offer a significant new contribution to knowledge.

By discussing your work with you directly and confirming that you fully understand your thesis, examiners can be confident that this is your own research.

Do all PhD students have to have a viva?

Almost always. One exception is for PhDs by publication (as the work in these will already have been through academic peer review). Some countries such as Australia and New Zealand also take a slightly different approach as their location makes it harder to invite external examiners for a face-to-face defence.

The viva format

Universities set their own viva voce processes, but most will follow a fairly similar format.

Before the exam

Many supervisors let you choose an external examiner . They need to have expertise in the topics you have researched, but not someone you have collaborated closely with during your PhD or who you have a strong personal friendship with (as these might create a conflict of interest).

Your supervisor will normally discuss possible options and then submit the invitation on your behalf. This usually happens just before you complete your PhD.

The next step is to submit your thesis . Nowadays most universities only ask for a digital submission which is sent out to your examiners for you.

The gap between submission and viva is usually one to three months. This allows time for both examiners to thoroughly read and consider your thesis and for you to prepare.

Your supervisor/s should offer to conduct a mock viva with you shortly before the real exam. They'll ask the sort of questions an examiner might have about your thesis so that you can practice answering and discussing them.

Your supervisor will normally meet with you before the viva begins to help you relax and ease any last minute nerves.

The exam room will be somewhere on your university campus that has been booked for the occasion. It will be laid out very similarly to a job interview, with space for you and the examiners to sit with your notes. Drinking water is also normally provided.

Most vivas are recorded and will begin with the internal examiner explaining the rules and regulations as a formality. Either they or the external will then begin asking questions about your thesis.

The examiners will usually help you relax and settle in to the discussion by asking something quite general, such as what interested you in this PhD project or what the most enjoyable part of the research was. Subsequent questions will be more specific, often referring the arguments made at particular points in your thesis.

The examiners will end the viva once they have completed their questions and feel able to come to a judgement. You will then be asked to leave the room whilst they discuss your performance and decide on a result to recommend. This normally takes around fifteen minutes or so.

After the viva

The next steps depend on your viva result. The examiners will invite you back in to explain their recommendation and provide general feedback on your work. This may include advice on whether or not you should seek to publish any of your PhD thesis and what sort of edits or further work might be required to prepare it for that.

Hopefully you'll then be able to celebrate with your supervisor, but they should be on hand to offer their to support and advise you whatever the outcome.

The majority of students have some corrections (usually minor) to make before resubmitting a final version of the thesis to be checked by the internal examiner. Once the final copy of your thesis is approved, you will be awarded your PhD! It's time to look forward to using your new title (and wearing some exceptionally elaborate robes at your graduation).

Viva preperation tips

It may feel like you're at the end of a long PhD journey by the time the viva comes around (and you are) but the oral exam is an important part of your doctorate and you should prepare accordingly.

Whatever else you do or don't do, listen to the advice of your supervisors. They'll have experience of all sides of the process, from sitting their own viva voce to preparing previous students for theirs. Chances are they've also served as internal or external examiners too and will know exactly what sort of questions they'd ask about a thesis like yours.

Here are seven tips for effective viva preparation.

#1 Take a (short) break first

Chances are you've been working very hard on your PhD recently, getting it written up, responding to feedback from your supervisor, making edits, sorting the bibliography (which you still left to the last minute, right) and getting the whole thing printed in time for the final deadline.

Whatever happens next, you've just successfully submitted a PhD thesis and you deserve a break. So take one.

A week or two away from your PhD will be ideal (no, don't take a copy of your dissertation with you). You'll get some mental rest and be in a better place to take a fresh look at your thesis and think clearly about it.

There's no need to feel guilty: the time between submission and viva is partly intended to make this possible.

#2 Read through your thesis

You may feel pretty familiar with your thesis by now but, actually, you aren't. You're familiar with a series of chapters that may well have developed separately over several years. It was probably only recently that you wrote them up in their final form, added an introduction and conclusion and turned the whole thing into a dissertation setting out your entire PhD thesis.

You need to know that thesis inside out and be completely familiar with the structure of the dissertation that contains and communicates it: which page a key concept or topic appears on for the first time, where key stages of your argument occur, where you cite or critique particular scholarship, and so on.

At the very least, this means reading your full thesis through at least once. Really though, you should be re-reading each chapter a couple of times and. . .

#3 Annotate key points

The PhD viva isn't a closed-book exam and you're expected to take a copy of your thesis with you. It's perfectly fine to consult it in response to questions, so make that process easy by annotating the most important stages of your argument.

There are lots of ways to do this, but, really, there's no substitute for sticking markers through your dissertation and scribbling in the margins.

If the copy of the thesis you take into the exam room looks like it's survived an explosion in a post-it note factory and then spent several years being read by rough-fingered undergraduate students in the library, well, you're on the right track.

#4 Note down potential questions (and answers)

You'll never be able to guess all of the questions that will come up at your viva, but you should be able to anticipate a few of them. Sketching out some bullet-point answers in advance will help you think critically about your thesis and boost your confidence going into the exam.

Spend extra time on any questions you're concerned about. If there's a point where your argument gets a bit strained or where you think your conclusions might be easy to challenge, have a think about how you'd defend them. Remember that your thesis doesn't have to be perfect, but you do need to be able to make a case for it – so practice doing that.

Incidentally, no one has been able to completely test the hypothesis that preparing for a viva question ensures it doesn't actually come up, but, well, the anecdotal evidence is strong. Prepare anyway.

#5 (Re)familiarise yourself with your examiners' work

The viva is about your thesis, but your examiners will have been selected due to the relevance of their own research and their perspectives will be at least partly informed by it.

It makes sense to consider how their work might inform their attitudes towards yours (this should also help you antitipate some questions, as above).

#6 Definitely take up the offer of a mock viva

Your supervisor/s should offer to arrange a mock viva with you shortly before the actual exam (once you've had time to prepare). This is a really helpful process.

The mock viva won't be anything like as long as the real thing and it won't cover every question your examiners will ask (or necessarily predict any of them). But it doesn't need to.

The most valuable feature of a mock viva is to get feedback on how you answer questions. Your supervisors will be able to spot whether you're coming across as too hesitant or too confident, or whether your answers are sufficiently clear.

#7 Try to enjoy it

Chances are you'll be sick of hearing this advice by the time your exam comes around, but it's true. A PhD viva voce really can be fun.

This is your chance to sit down with two experts in your academic field who have read and carefully considered your thesis and whose attention, for the duration of the exam, is entirely on your research. That's a privilege and it's one you've earned by getting to this stage.

Prepare effectively and give the viva voce the respect it deserves. But, once you get into that exam room, be confident, own your ideas and enjoy the chance to let them take centre stage in a serious academic discussion.

Viva results

The vast majority of PhD students pass their viva. By the time you're ready to submit your PhD you will be an expert in your subject area, more than capable of discussing and debating it. You'll also have done so many times before: at conferences, in conversations with your supervisor, and in your own writing.

Your supervisor will also ensure your thesis is ready for examination before they recommend you proceed to this stage. The only exceptions to this will be if you submit against the advice of your supervisor (never a good idea) or if you've over-run the time period for your PhD and have to hand in a thesis that isn't ready (you're unlikely to get to this point unless your PhD has been going badly for some time).

PhD viva outcomes

It's rare to fail a viva, but it's also rare to pass outright. Instead, most students are asked to make some corrections to their thesis.

Here are the possible outcomes of a PhD viva voce:

• Pass with no corrections – (uncommon) – Your viva has revealed no significant issues with your thesis and the dissertation itself is error-free. Congratulations, you are eligible to receive your PhD now!
• Pass with minor corrections – (very common) – Your thesis is essentially sound, but there are some minor issues with your dissertation (such as typographical errors, or missing references). You will normally have three months to submit a corrected thesis.
• Pass with major corrections – (fairly uncommon) – There are some parts of your argument that need to be clarified, expanded or otherwise rewritten. You will normally have six months to submit a revised thesis, but won't need a second viva.
• Revise and resubmit – (fairly rare) – Your thesis is potentially good enough for a PhD, but it needs some significant work, usually including some substantial additional research. You will have around a year to re-submit an improved and updated version of your dissertation for a second viva voce exam.
• Be recommended for MPhil – (rare) – Your thesis isn't good enough for a PhD, but it is sufficient for an MPhil (a research Masters that doesn't require a substantial original contribution to knowledge). You may receive the MPhil outright, or after some edits and corrections.
• Fail – (exceptionally rare) – Your thesis does not meet the required standard for a PhD (perhaps due to fundamental flaws in your data and analysis, or due to evidence of plagiarism) and it cannot be converted into an MPhil. You have failed your doctorate and cannot resubmit your thesis.

Those last couple of results may appear scary but, in practice, it's only a few % of candidates each year who don't pass with corrections. The only way a PhD is likely to fail outright is if you have run down the clock on your registration period, submitted a poorly written thesis based on insufficient data and probably done so against the advice of your supervisor/s. The entire PhD process is designed to prevent this happening.

So relax. The likelihood is that your PhD will pass with minor corrections (or better) and that your next challenge will be deciding what to use your new 'Dr' title on first.

Can you appeal a viva result?

If you think your viva outcome was incorrect or unfair, then you may be able to appeal it with your university. The first thing to do is check their guidelines and appeal process. Your students' union may also be able to support and advise you.

Note that you can't normally appeal on academic grounds . Your examiners' judgement is generally final. It is also difficult to appeal a PhD result if you submitted without the support of your supervisor/s or have otherwise ignored their advice at other points in your project.

You may have grounds for appeal if you can demonstrate that you have been poorly advised or supervised (you will need evidence of this and of the specific impact it has had) or if there was an irregularity in the conduct of your viva (such as interruptions, an unsuitable venue, or a lack of consideration for relevant disabilities or health conditions that may have impacted your performance).

Common viva questions

The questions your examiners ask will obviously be very specific to your thesis and anticipating them is a big part of your specific viva preparation . There are a few things that are likely to crop up more often than not, though.

Here are some example viva questions , along with some tips for answering them well.

"Why did you choose this PhD project?" / "What interested you most about this topic?"

This is a classic icebreaker: it's an invitation to speak generally and positively about your work. As well as being a fairly easy question to answer (after all, there must be at least something you enjoyed about your PhD) this should also help you channel your passion and enthusiasm for your research as the viva gets going.

"What was the most challenging part of the project?"

This probably won't be the first question you're asked, but it might also come up early in the viva as the examiners ease you into talking about your project. It doesn't mean that they think your PhD is flawed. All research involves overcoming obstacles. This is an invitation to talk about how you did that and reflect on the practicalities of your project.

"What is the original contribution to knowledge made by this thesis?"

This question is highly likely to come up at some point in the viva and it's one you absolutely must have a clear answer for. You should be able to explain in one or two sentences what your contribution is, how it's original and why it matters.

Some examiners might not be so explicit or direct in asking this, so be on the lookout for questions like "why is this PhD important?", "why was this project worth completing?", "what were your main findings?" or "why does this research matter?". If you hear any of those, it's time to deploy the original contribution answer.

"Why did you include / exclude X?"

All doctoral projects need to be selective about what they can and can't include, and successful PhD students need to set boundaries for their research. At some point your examiners will probably want to see the logic behind yours.

Be confident and own your decisions. If there was a particular topic or approach you didn't include, then give your reasons for that.

Remember that there are lots of reasons why something might not make the cut for a PhD and the examiners aren't trying to catch you out. They don't even need to agree 100% with your decisions, but they do need to hear that you had credible reasons for making them.

It may be that there wasn't space to cover everything (in which case you should justify prioritising the material you did include). Or perhaps you felt that there was already sufficient scholarship related to a particular source or concept and your aim was to take the field in a different direction (this is a very good answer, if you can make it convincingly).

"If you were to repeat this project, what would you do differently?"

This question (or one like it) may come towards the end of the viva as you reflect on the project as a whole.

Again, the aim isn't to try and undermine your thesis, but rather to see whether you can constructively critique your own work and approaches. Or, to put it another way, have you learned anything from the experience of doing a PhD? You should have. After all, a doctorate is partly about learning to become an effective researcher and mistakes are a great thing to learn from.

In any case, this shouldn't be too hard to answer. There are likely to be all sorts of things you would do differently in future: from adopting different approaches or directions sooner, to heading off blind alleys or methodological mistakes.

"What do you think the next steps might be for this research?"

Relax, your examiners aren't expecting you to dive straight into another PhD. But they may want to hear where you would take this research next, or what you think other scholars could do to build on your findings. After all, part of the value in a new contribution to your field should lie in what it makes possible, as well as what it is .

It's best to be modest and realistic here, rather than making sweeping claims for how your findings will allow other researchers to reinvent the wheel (unless you have actually come up with a new technique for designing wheels, in which case, go ahead).

"Do you have any questions or comments for us?"

Your examiners will probably end the viva by asking if you'd like to ask them any questions, or say anything else about your thesis. This might seem a bit odd, but it's actually a helpful way for you to revisit or clarify any of your earlier answers.

For example, you might like to acknowledge a specific critique and reiterate your reasons for believing the thesis to be valid in spite of it. Or you might want to confirm that the examiners understood what you meant at a particular point in the previous discussion.

It's not a good idea to try and rehash large chunks of the viva here, but it's fine to pick out one or two things and be assertive. This demonstrates your confidence and commitment.

Equally, you can take the opportunity to ask the examiner's opinions on areas of the thesis that haven't come up, if you wish. This is fine, provided you're confident in those sections and comfortable discussing them.

How to pass your PhD viva

Five tips to a less painful thesis defence 

In most of Europe, the PhD viva is a formality. In Finland, you get a ceremonial sword. In Australia, it doesn’t exist at all. But in the UK, the oral viva (or, in the US, the thesis defence) is an integral part of achieving a doctorate. In a gruelling two-hour (or more) face-off with internal and external examiners, the candidate must prove they can support their thesis and are ready to become an independent researcher.

Vivas: because who doesn’t want to be grilled for two hours about a subject they are thoroughly sick of thinking about?

The viva is not universally popular. With little regulation or standardisation, many academics feel it is no longer fit for purpose. And while there are few outright failures, the level of fear and anxiety around vivas is high. University of Bath, UK, chemist Oli Weber, who successfully completed his viva in May, had heard these stories too: ‘that was very much in my mind beforehand, because you just don’t know until its actually underway how it’s going to pan out.’

It was after a bad experience as an examiner that Pat Sikes, a sociology professor at the University of Sheffield decided to look into these stories. She collected accounts from a group of around 20 examiners. 1  The horror stories recounted to her mostly related to examiners with grudges or long-running issues between candidates and their supervisors. However, Sikes herself is not against the practice: ‘I’ve been in a number of vivas where the outcome that the examiner thought was going to be didn’t happen, and often for the good of the candidate,’ she explains. Of her involvement with 160 odd vivas, she says only five stand out as being horrendous.

‘It is very rare for people to have a viva which is a totally negative experience,’ adds postgraduate skills trainer Nathan Ryder. Using his own experience completing a PhD in mathematics, he has created a ‘viva survivor’ workshop designed to help postgraduates prepare. He has also recorded viva experiences in a podcast and created a free downloadable advice booklet.

So how should you prepare for you viva?

Present your thesis well

Make it easy for the examiners! ‘I’ve never come across an examiner who sets out to be unpleasant, but I’ve come across examiners who get irritated by the work they have been asked to examine,’ says Sikes. ‘That’s often because the work is badly presented, and takes far too much energy on the part of the reader and this feel disrespectful.’

Weber adds: ‘Make sure that there aren’t too many leaps in thinking and arguments that you can’t defend.’

Read your thesis from cover to cover

Ryder says the most important task is to read your thesis. ‘Line by line. Don’t skim it, don’t just focus on the good bits or the bad bits, where people’s preferences lead, but really read it.’ He also suggests annotating and highlighting the text or using post-it notes to help find each chapter or important results – this will prevent that feeling of panic when you can’t find what you are looking for in the viva.

Revise the wider field

You may be asked questions around the wider topic of your work, so make sure you are well read in the area, including reading your references. Weber did this for his PhD on thin-film perovskite solar cells. ‘It was really helpful to read through the thesis and the research that we had published, but also to review all the basic theory to make sure that it was really fresh in my mind … I was doing some of this work three and a half years ago.’ Another top tip is to read up on your examiners’ work: they’ll probably want to talk about it!

Practice talking about your work

Some supervisors create a mock viva for their students. ‘I’m not convinced they are useful but a lot of my colleagues do them,’ says Sikes. ‘You are not going to have the same degree of stress and anxiety.’ However, Ryder says it is useful to talk about you work as much as possible and prepare summaries as you may be asked to introduce your project. He also suggests coming up with answers to some general questions, such as why this research interested you and what the results have contributed to your field.

Be confident

Ryder says the most important thing he does at his workshops is try and instil confidence in candidates. Sikes agrees that most people should be justifiably confident: ‘If failure was looking to be on the cards, people will generally have exited before they get to the viva.’ For most, she says, it turns into a positive experience. ‘These people have read your work more carefully than anyone else ever will and so you can have a really good discussion and at the end of the day most students come away and say there were challenges, but I really enjoyed it.’

‘There were definitely some difficult questions but nothing unfair, everything was very relevant,’ recalls Weber. ‘[The examiners] were clearly very engaged with it and quite positive.’ But, he says, ‘I think it’s hard for me to say that I actually enjoyed the process…’

5 tips for passing your PhD viva

Every Doctoral researcher is expected to defend their thesis through an oral test known as a viva voce - so discover how to prepare for your PhD viva and ensure you make a good impression on the examiners

1. Understand what's expected of you

The PhD viva exam has traditionally always taken place in person, with the interview style discussion overseen by at least two (internal and external) examiners. Afterwards, you would be provided with a joint written report detailing any corrections that need to be made.

However, during the pandemic, the online PhD viva become more commonplace with this exam more likely to take place via Microsoft Teams, Skype or Zoom. Even now, a number of years later, many universities still allow for the viva to take place online, or a hybrid of online and in-person assessment.

The virtual experience still follows much the same format, but you'll be briefed in advance about the arrangements and any technical aspects to bear in mind. You can prepare for an online PhD viva by reading our video interview tips .

The chair of the viva is usually the internal examiner, although it can be an independent person. If you and the examiners agree, your PhD supervisor can also be present.

The examiners' main objective is to ascertain that you've written your own thesis, so if you have and are ready to talk through how you completed it, there's no need to panic. You may even enjoy the viva voce test.

In addition to assessing your thesis, the examiners are also there to assist you in deciding how and where this research might be published.

There are various results between a 'pass' and 'fail' but it's very rare to slip up at this point of a PhD. Most Doctorate awards will be made upon the condition that a number of minor corrections are made, with re-submission requests far less common.

While the pass rate is high, the viva exam itself can still be intellectually demanding. This is because you'll be debating issues that are conceptually complex, so preparation is crucial to your success.

At the end of it, whatever the outcome, be prepared to take on board any advice, as the examiners are there to help you improve your argument or the presentation of your thesis.

2. Know your thesis inside out

While this isn't a memory test - as you're fine bringing notes and a copy of your thesis with you - it's still important to gain a good understanding of what you've written and be knowledgeable about your field of study.

You'll need to think carefully about where this original piece of work would be placed in the context of the wider body of research carried out in this field. Questions will be asked about this, as well as whether the project could possibly be developed further through any future research.

As you'll be explaining parts of the document to the examiners (who'll also have a digital or physical copy), make sure the pagination is the same in your version as the one they're looking at to avoid any issues regarding everybody being on the same page.

If you get stuck at any point during the viva exam, you can use looking at the thesis as an excuse to re-focus and gather your thoughts.

3. Anticipate the PhD viva questions

The examiners will have prepared a series of questions for you to answer at the viva voce, but this is nothing to get too concerned about. The questions will all be based on your thesis - what it's about, what you did and what you found out - and why this matters, in relation to your field of study.

So when getting ready for the viva, consider the types of questions you're likely to be asked, including:

• What original contribution has your thesis made to this field of study?
• Explain the main research questions you were hoping to address.
• What are the strengths and weaknesses of your thesis?
• If you had to start the thesis again, what would you do differently?
• If funding was no object, describe how you'd follow on from this project.
• What are your plans for the future?

It can be helpful to practise your answers beforehand, ideally vocalising them by arranging a mock mini viva - although, as you aren't restricted in terms of referring to notes in the exam, you can leave room for spontaneity, and you don't need to learn it all off by heart.

If your viva is being held online, you can ensure any technical issues are identified before the day by having a run through with your supervisor or a friend.

While it may sound simple, stick to answering the questions posed. It's really easy to go off on a tangent and this can open up other lines of enquiry from the examiners - possibly in areas you hadn't expected to be quizzed about.

On the other hand, it's completely fine to bring personality to your reasoning and use stories as a means of describing the learning process you've gone through and the techniques mastered over the last three or four years that have brought you to this point.

4. Learn about your examiners' own work

The senior and well-respected academics who'll be reading your thesis will have their own ideas on conducting PhD standard research. Therefore, it's worth taking a look online at their academic and LinkedIn profiles to discover if there's any correlation with the research they've had published and your own work.

From this, you should be able to gain a better idea of their motivations, their possible views on your thesis and the kinds of questions they might wish to discuss after having read through it.

You should research up-to-date theories, read any recent papers on the subject and speak to others who've recently had their own viva exam. Think about how your work differentiates from the research carried out by others in your chosen field.

Prepare to provide any supporting evidence asked of you by the examiners - for example, they may request to see experimental data you mention once the exam is over.

It's also necessary to check the policies and practices in place at your university and be sure of what the roles of the examiners are and how the viva panel will be structured. In many cases, Doctoral students can choose the examiners conducting the PhD viva.

5. Plan towards the viva exam

From the moment you know the date of your viva voce, work backwards and plan the steps you'll need to take before the day itself. Allow enough time to assess and review your work so that as the day approaches, you can focus on the practicalities.

This encompasses everything from making sure you relax, eat and sleep well the day before to arranging transport so you get to the viva on time.

An online PhD viva will present its own challenges, so ensure your working space is presentable and you still make an effort in terms of what you'll be wearing.

It's always advisable to adhere to interview etiquette and go with something that's both smart and comfortable. By looking the part, this should get you in the right frame of mind to communicate in a professional manner.

In the build-up, avoid any situations that might make you feel stressed and instead try to adopt a positive attitude, one that results in a genuine eagerness to engage in a debate about the work you've been toiling over.

If you're travelling to the exam, be sure to check that you have everything you need, including the thesis, plus any notes or other materials that will help support your claims.

The Doctoral viva can last between one and four hours - usually two - so it's necessary to pace yourself to get off to the best possible start.

Remember, the examiners aren't trying to trip you up - they want you to pass and are primarily there to hear you talk about your project. So, after the polite introductions, they'll typically start with an icebreaker to put you at ease and help calm the nerves.

It's meant to be an open and honest conversation about your work, so feel free to politely disagree with the examiners, especially on areas you feel strongly about. Don't forget to use examples from your thesis to back up what you're saying, remembering to be clear and concise.

If you know your way around your thesis and can explain your thinking and way of working, this test shouldn't be a problem. And if you don't know the answer to a specific question - admit it, as it's better to concede your limitations in an area than ramble on and hope they don't notice you're struggling to come up with an explanation.

Remember that no research is perfect, so it's important to appreciate this during the discussion - but don't be too overcritical about your work either, as that's not your job.

Finally, as the PhD viva can quickly move from a series of friendly questions to those that are more in-depth, take some time to think before answering. Don't worry about any periods of silence from the examiners, as this certainly isn't an indication that you're doing badly.

Promoting, discussing and celebrating teaching at the university of edinburgh, vive-ing la viva: how to answer viva questions.

Dr Jenny Scoles from the Institute of Academic Development provides some helpful tips in how to prepare for your PhD viva by being aware of how you answer the examiners’ questions. This post is part of the Learning and Teaching Enhancement theme:  Showcasing the Doctoral College .

Just enjoy the viva, they say…. ha!

‘Enjoyment’ was not at the top of my list of adjectives when thinking about my viva. But I knew it was my only chance at speaking to people who had actually read my thesis and, unlike my long-suffering family and friends, were genuinely curious about why I didn’t use NVivo and why I hadn’t referenced the original citation on page 243. So, when it came to prepping for my PhD viva a few years ago (I submitted in a September and my viva wasn’t until the January so I had a decent amount of time to prepare/find multiple spelling mistakes), I made sure I was as ready as I could be.

I found a lot of online viva resources  and  blog posts that provided helpful lists of likely and possible questions you may be asked, so you can prepare your answers. However, what I found most helpful were the tips from my supervisors during my mock viva (tip 1: have a mock viva with your supervisors). Specifically, they talked about HOW I should answer the examiners’ questions, not necessarily WHAT to answer. Here are some examples:

Sign post your answers:  You will undoubtedly be asked, in so many words, ‘What is your original contribution to knowledge?’. As with all replies, keep your answer clear; don’t make things too complicated. Structure the points you want so you can signpost the examiner to your main thesis contributions, just as you would have in your written conclusion. For example, I said ‘My thesis makes three original contributes to knowledge: firstly, a theoretical contribution… secondly a methodological contribution… and thirdly, a pedagogical/practical contribution….’, and kept it to a few sentences for each of the three points.

It’s a stamina game:  It is easy at the beginning of the viva to want to just keep talking, through nerves, or a worry that you want to show off everything at once. My viva was only an hour and a half, but I’ve heard of some lasting over five hours – it just depends on the examiners, and what emerges on the day. Have faith that, when answering the first few questions, you don’t have to reel off your whole thesis there and then. Take your time; it is a tiring and exhaustive few hours. I hit the wall after an hour as I’d begun to relax into it, and my adrenaline dropped (I remember doing a few over-loud sighs without realising). So, pace yourself. If you are worried that you have not answered their question, you can politely ask if they would like you to expand any more.

Although it’s a defence of your thesis, don’t come across as defensive:  This is a hugely useful distinction that I was made aware of. The examiners are there to critically pick apart your thesis, probing why you did certain things and not others. Yet this thesis is your baby, and no one but  you  can say your baby isn’t perfect. So your hackles rise, and perhaps, without realising it, the tone or manner in which you reply could come across as too defensive and it could make the examiners feel defensive too;   they’re only human, after all. You can still defend your reasons politely but firmly… ‘That’s a really interesting way of looking at it, but I found, for my study, it was more helpful to look at it this way….’, or similar.

Don’t know the answer? Sometimes they may ask you something that you have not even thought about, let alone prepared for. At this point, have a few stock phrases up your sleeve to give yourself some time to mull it over:

Well, now that I think about it like that… I’m only starting to see this now… That’s a very good point, I’d like to look at this issue in more detail.

Practice speaking your answers aloud to get used to your voice:  The best prep I did was with a colleague who had her viva at a similar time to me. We scheduled weekly Skype sessions in the weeks before and practised asking each other unseen questions. This helped me get used to hearing my own voice, and let me play with how I could verbalise concepts and ideas that I had only, up until then, put into writing and lived in my head.

Prepare your own questions:  Like an interview scenario, it looks professional if you have a few prepared questions for the examiners for the ‘any questions?’ part, at the end. For example, you could ask their thoughts on where you could publish future journal articles from your PhD. Or, how a particular concept you developed fits with their own work (brownie points for having read the examiners’ latest papers).

And, finally, two tips from me after having survived:  

Simplify the notes you take in with you:  I was allowed to take in as many notes, thesis drafts, books, lucky mascots as I wanted. However, if you are relying too much on your answers coming from reading your notes, the flow of conversation will falter, and you may end up getting into a bit of a sweat. As part of the revision process, I made colourful mind maps that summarised the main points I wanted to make for each potential question. I took these in to the viva and lay them out in front of me, which meant I could flick my eyes to them if I had a mind-blank:

Enjoy it… or just get through it: It’s easy to say ‘just enjoy your viva!’ once you’re through the other side. So, if you enjoy it, bonus! If not, well-bloody-done for having got to the viva in the first place, and whatever happens, reward yourself big-style at the end:

Viva Questions

• Updated on  
• Jan 18, 2024

What are viva questions? A viva simply means a university examination during which students answer questions in speech and these questions are commonly based on a particular project or discipline. Viva questions are an important part of an academic program and often take place at the conclusion of a semester/year. Although viva questions can vary, they commonly focus on four aspects: “What the project is about?”, “What were the key findings or observations?”, “What was the process?” and “Why do the observations matter?”. However, in some cases, these questions can be more diverse. If you want to know how to tackle these PhD viva questions properly, then this blog is a must-read for you!

This Blog Includes:

1. summarize your project/thesis/research in 3 minutes, 2. what is the strength and weakness of your research, 3. what makes your thesis work original, 4. elaborate on how your findings relate to literature in your field, 5. tell me about yourself, 6. summarise your key findings, 7. highlight the strong and weak areas of your research, 8. what were the major motivations behind this research, 9. elucidate the process of evaluation, 10. what is the key focus of this research, 50 common viva questions, 25 phd viva questions , viva questions on research methodologies, analysis and research findings: viva questions, viva questions for physics, viva questions for chemistry, viva questions for biology, viva questions for higher education, tips and tricks to ace the viva, 10 most important viva questions with answers.

Whether you are a PhD or a school student, viva exams are equally tough for everyone. But don’t worry, we have a solution to calm you down! Here are 5 commonly asked questions with answers:

To answer this question correctly, you need to be well-versed in the entire project. Start with an answer by explaining why did you select the topic of your project/thesis/research and close your explanation by providing an optimum solution to the problem.

Carefully analyze the strength and weaknesses of your research and while answering, make sure you talk about your weaknesses also and not only your strengths.

While answering, keep in mind what was known before and what you have added as part of being awarded your PhD is to contribute novel knowledge.

Explain how your findings connect with the literature review of your project and what its contributions are in terms of the field of your research. Does it further expand the literature? Does it highlight some new observations? Does it add to the literature in this field? Answer these main questions.

Talk about yourself and your areas of interest. Focus on the areas you are extremely positive about. Talk about your past achievements and what brings you to this position. Keep it professional.

For this common viva question, focus on what you observed and found through your research project, how it connects with your hypothesis as well as what concluded through this research.

Mention the strengths first and elaborate on how they connect with the key findings. Then, you can underline the weak areas and the factors that could have been transformed into strengths.

Focus on what inspired you to carry out this research, and cite certain instances which helped you select this topic as well as the field for your project.

Elaborate on how you evaluated the key findings in your research, the key factors involved, whether the evaluation process faced some obstacles, how it could have been better and what was the reason you choose a particular process of evaluation.

While answering this, keep a summarised version of your research in your mind and then talk about the area of the primary focus of research. In order to demonstrate that your research is viable, it is essential to identify some of the key questions that it addresses.

Mostly research-based viva questions are asked in the case of a doctoral thesis wherein the key aspect of the process is to identify the thought behind the development of the specific paper. It is done to determine the knowledge and originality of the researcher and to assess their further interest in the field.

Below are some of the most common viva questions.

• Tell me about yourself . 
• Summarise your research/thesis in 3 minutes.
• Tell us how your research contributes to knowledge discourse.
• What are the practical applications of your research?

A PhD viva is a final examination in which a candidate answers questions from an academic panel on their work and understanding of their chosen subject area. This is often used to determine whether the candidate has effectively proved that they have learned enough about their specialised study topic to produce original work.

During a PhD viva, the questions are frequently based on the original study proposal and any other written material that has already been provided. Read the top 25 PhD viva questions below:

• What is the area in which you wish to be examined?
• What have you done that merits a PhD?

• Where do current technologies fail such that you (could) make a contribution?
• Who are your closest competitors?
• Can you summarise your project in 2 lines?
• How can this research help other students working in the same field?
• Which of your findings is your personal favourite?
• Is your research inspired by some incident in your life?
• Why did you choose this method to conduct this research?
• What motivated you to conduct this research?
• What was the biggest challenge that came your way?
• What were the alternatives to this methodology?
• How would you evaluate your work?
• Were you short of any resources while conducting this research?

Subjective Questions for School 

Be it for Chemistry or Biology practicals , from 10th standard onwards, students have to appear for vivas. The concerned viva questions pertain to the subject that the students have studied in the course of the entire year. The viva that one appears for at the senior secondary level is based on the experiments that the students perform to test their understanding of the research. Apart from those experiments, the students are also asked several questions to estimate their practical understanding of the key areas of study. 

Viva questions for Physics are mainly based on concepts and topics from Physics textbooks. Here are the most common viva questions for Physics Class 11 and Class 12:

Viva Questions for Class 12 Physics

• What is Ohm’s Law?
• What do you mean by ‘interference’?
• Define tangent law.
• Name the type of motion shown by the Torsional pendulum.
• What happens with resonance in the LCR circuit?
• What do you understand by the order of the spectrum?
• How is Wedge Film Experiment useful?
• Define parallax and how it is removed.
• How does the emission of light is carried out by LED?

Admission tutors at the postgraduate level conduct viva or interviews to establish whether graduates are committed to and prepared for studying the master’s or PhD level courses. These are less formal than a job interview , but you still need to take them seriously – your aspirations to pursue overseas education could depend on your performance.

Let’s say you come from a Mass Communication background and you’ve made a documentary on “ underprivileged sections of society” . Then you might be asked about the process of the development of the movie, how long did it take to gauge the key aspects of the film or the perspective behind the direction process.

Though the research you do in your PhD is a massive achievement, you need to be prepared for the exhaustive viva session with the experts. The PhD viva questions are a chance for students to discuss their work with professionals. Its formal purpose is to ensure that the student understands and can explain their thesis. It involves lots of stinging questions and conceptually complex debates. How can PhD scholars best prepare themselves? Let us take a look at the different tips for getting through your viva questions:

• Calm down and breathe
• Believe in yourself
• Do something fun
• Go in with a good attitude
• Look presentable
• Read your thesis
• Know the rules
• Make a list of your own corrections
• Make plans to celebrate
• Try to enjoy it

Ans. These are some of the basic viva questions: Tell me about yourself. Summarise your research/thesis in 3 minutes. Tell us how your research contributes to knowledge discourse. What are the practical applications of your research? What is the strength and weakness of your research?

Ans. Every institution is different; some have only two examiners, while others include a convenor as well. Some institutions may require you to prepare a talk to present before the viva (this was the situation for me, and it was excellent preparation for the exam).

Ans. The examiners will frequently begin a viva with an introductory question, such as “Spend five or ten minutes telling us about your work, what you have done, and what contribution you have made” or “Summarise your work for us in a single sentence.” These are some of the first PhD viva questions that you can encounter.

Preparing for the viva questions beforehand helps you confidently answer them in front of the panel of experts who not only test your subjective knowledge but also do grading on the basis of your level of confidence.

what should be an ideal answer for the question “tell me about yourself?”

There is no ideal answer to the question ‘Tell me about yourself’, as it is very subjective and depends on your career trajectory. But the best way you can answer it is by covering the following points:

1. Share your background 2. Tell them about your education 3. Share any volunteer, internship or work experience you have 4 You can also tell them about your hobbies

It is advisable that you share your experience chronologically so it does not get confusing for the interviewer.

14 top tips to help you prepare for the PhD viva

doctoral-academy-blog

• doctoral academy
• postgraduate

The viva examination can be an exciting but nerve-wracking experience – the culmination of years of hard work and research. Prior planning for the event will help ease the nerves and boost your confidence.

The following ideas are taken from publications, my own experience and discussions with other PhD students and should help you prepare for a more enjoyable viva. You don’t need to do all of these. Remember, if you’re at the stage where you’re preparing for your viva, you’ve already done 99% of the work!

1) Annotate your thesis I used highlighters and different pens as well as post-its indicating emphasis, important literature, the contribution of the study, typos, useful extracts, and sections.

2) Find out about the viva process Who will be there? What are their roles? Would you like your supervisors to attend? Take part in the Cardiff University Doctoral Academy viva course to understand what to expect.

3) Do some (more) research Look at the examination procedures, university guidance, and criteria. To what extent does your thesis meet the criteria?

4) Get reading I read the book How to Survive Your Viva: Defending a Thesis in an Oral Examination by Rowena Murray; it is filled with helpful information about viva preparation.

5) Think ahead Plan certain topics in advance that you can refer to during the viva, such as:

• the key authors/main studies in the field
• the gap in research and your original contribution
• a short summary of the thesis
• a more extended summary of the thesis
• summaries of each chapter
• questions for the examiner
• the highlights of your thesis

6) Practise and rehearse What are the most commonly asked questions in your field? Plan and practise your answers in advance. Elaborate; plan how you can extend the answers. Think about how to say what you did and why you did it. I found listening back to recordings of myself answering some trickier questions really effective.

7) Buy yourself time Plan what you will say if you do not know the answer to a question. The examiners may ask you things that you have not thought about. You are allowed to ask for clarification, or you can come back to the question later.

8) Present at a conference This will help you to practise articulating your work to others, get used to answering questions about your research and gain confidence. You know your research better than anyone; be ready to defend it.

9) Mock it up Arrange a mock viva with your supervisors or ask a colleague to ask you questions. Practise giving concise and confident answers in an examination situation.

10) Look at the examiners’ work You are probably already familiar with what they have done; they may ask about things they are interested in and have published about.

11) Listen to podcasts The PhD Life Raft podcast has excellent episodes, such as  Preparing for Your Viva , and What Does a PhD Examiner Look for in a Thesis? . Some Viva Survivor podcast episodes could also be beneficial.

12) Visualise and mentally prepare Imagine yourself in the viva situation, successfully discussing your research. Think about all the achievements, the efforts you have put in, successes, and positive feedback throughout your PhD. Everyone gets nervous. Can you rest, exercise, or do something enjoyable in the days leading up to the viva?

13) Prep your ‘on the day’ details What will you wear? Pack paper and pens for note taking and the annotated thesis. What else are you going to take with you? The viva can last up to a few hours; will you need water, food, or your laptop?

14) Finally, try to enjoy the big day! The viva is a unique opportunity to discuss your work with experts in the field. They have spent time reading your thesis; now is your opportunity to demonstrate your contribution, your knowledge of the field, the work you have put in, your learning, and your research skills.

5 Tips for Preparing for Your PhD Viva

• By Zebastian D.
• December 13, 2019

You’ve just passed a massive milestone: writing and submitting your PhD thesis. This has been the culmination of at least three years of work and is definitely a cause for celebration. But the journey’s not fully over just yet – you still have the viva to pass. In the UK the viva usually lasts a few hours and involves a detailed discussion of your thesis with two expert examiners; your primary supervisor may or may not sit in this. Expect the viva to be tough – you’ll need to be able to defend your PhD thesis and respond to questions designed to probe your understanding of your subject. But if you prepare for it well, you’re likely to come out of it having had an enjoyable experience discussing your work with people genuinely interested in your project.

Here are some tips to help you prepare for the day.

1. Know Your Thesis

You should expect your examiners to have spent a considerable about of time going through your PhD thesis and the content of it will be fresh in their mind; make sure it’s fresh in yours too. Yes, you’re the one that’s written it but, if you’ve planned well , you may have written some of your chapter content quite a while ago. Equally, I would definitely recommend checking to see if any new papers in your field have been published since writing your chapters and submitting your thesis.

2. Know Your Examiners

Your examiners will be experts in their fields, and at least one (if not both) will be experts in the same field of your research. Make sure you look up papers they’ve published and think about how they fit in with your work. It’s likely that some of their line of questioning in the viva will be based around their contributions to the research area.

3. Think of Possible Questions

It’s a good idea to spend time with your supervisor to think of possible questions the examiners may ask you. In particular, can you predict the tough questions that might come your way and how you might best answer them? Are there any areas within your work that you would consider as limitations for your studies and that you should be prepared to acknowledge? Some preparation here and even a mock interview will go a long way in making the actual thing feel easier.

4. Bring a Copy of Your Thesis

Make sure you have your own printed copy of your PhD thesis that you bring along with you to the viva. Make notes and highlight pages and sections within it that you especially want to bring attention to. You might also find it useful to print separate larger copies of key results (e.g. graphs or figures) that you think would be useful to discuss. Some props that help explain concepts (if relevant) can also be a brilliant way to guide the discussions to areas you’re most comfortable with.

5. Focus on Your Strengths

Try to view the viva as an opportunity to showcase the new knowledge you have added to your field of research. Focus on the positives that have come out of your work; all projects will have some areas of weakness but there’s no need to highlight these to your examiners unless directly asked about them. Coming into your viva with one or two papers published (if possible) is a great positive – it’ll give you confidence that your work has already stood up to peer-review and is a very good way to present your contributions to research.

A science investigatory project is a science-based research project or study that is performed by school children in a classroom, exhibition or science fair.

Considering whether to do an MBA or a PhD? If so, find out what their differences are, and more importantly, which one is better suited for you.

13 steps I took to prepare for my PhD viva

Published May 29, 2017 by Salma Patel

I submitted my thesis in Dec 2016. It took much longer than I had anticipated for the examiners and the chair to be approved due to administrative delays. Two months later (in late Feb) I received confirmation that my exam would be at the end of April.

In terms of the arrangements of the day of the viva, I must say the graduate office in my department were great and said they would organise the day, and I should only worry about preparing for the exam. I booked advance tickets so I could get to the University early and not have to pay a peak time train fare. I have a written about my viva experience here .

From Jan-March I was working with the public health team at Hackney City Council. I also had Open University marking to do in March. So I started preparing for my thesis approximately a month before my viva, and this is how:

Step 1: The first thing I did was read this really useful three part blogpost by Fiona Noble. I decided I was going to tackle the preparation in a similar fashion.

Step 2: I knew I had to read the thesis cover to cover , but I was dreading it. I was overcome by fear that I may open the first page and spot mistakes. Or I may start reading it and realise it is a complete rubbish. So I procrastinated for two days, looking for any excuse not to open the thesis, which is so unlike me. On the third day, I was forced to work in a cafe and lo and behold, I managed to read almost half the thesis. Whilst reading the thesis, I placed post it notes where I thought I may be asked a question, where I thought something may not be clear and also the references that were not fresh in my head. Because it had been three months since I had last read the thesis, it really felt like a fresh read, and when I completed reading it, thankfully I said to myself ‘it isn’t bad at all’ (which means it is good!).

Step 3: I then sat at my desk with my computer, and started to go through all the post it notes . Where it was in relation to a reference, I re-read the abstract of the paper, just to refresh my memory, and placed a short summary of the paper or the paper title on a larger post it note and stuck it inside the thesis, next to where it was mentioned. I also went through all the other post it notes, answered the questions, and left small post it notes inside the thesis, in case I would be questioned in my viva and I’d forget the answer.

Step 4: I prepared questions that could come up in the thesis in a Q&A document . I looked online, and found many questions, and I had also bought PhD viva cards a year or so ago. I also went through the archive of the PhD Viva website which I had set up in 2012 (but very sadly hacked and and deleted). So I sat with about 5 different long lists of questions and the cards in an attempt to amalgamate them, so that I would end up with a very thorough list of questions. I did that, and towards the the end I realised that the list of questions from this list published online was actually very comprehensive, and pretty much covered everything that was on other lists (I have copied the list of questions from that resource at the end of this post in case the online resource goes haywire). I sat and typed up the answers to these questions in note form in a Word document. I realised quickly that the answer to most of these questions was narrated in my thesis, so there was much copy pasting too. Rowen Murray’s book ‘How to Survive Your Viva’ is a book I dipped into regularly, during this stage and other stages too. It isn’t an essential read, but it is really detailed, and if you are not feeling confident about answering the questions, it suggests really good ways to approach the answers.

(NB: After I completed this step I found this resource:  list of 40 viva questions , which is shorter but looks almost as good too (and in hindsight post-viva, I think it is a better set of questions).

Step 5: I then received an email from my main supervisor asking me to prepare a 10 min presentation for the mock viva, an answer to the question ‘Tell me about your research’ , as this is always the first question. She suggested that I should structure it as follows:

• about you – what disciplinary perspective are you approaching this from? Your motivation for doing the research topic.
• research problem, aims, research questions
• methodology
• conclusions and contributions

I was a bit taken aback to be honest at this point as I wasn’t expecting this type of open-ended question, and I hadn’t really come across it in the notes or books I had read, but once I had a think about it, it made sense that the first question is likely to be quite open-ended, and as she advised, it made sense to prepare for the first question thoroughly, as it gives you a good strong start. So I created a Powerpoint using a similar structure to the above (motivations for research, originality of the research, research question, findings, key contributions to knowledge, and key contributions to practice). I had already prepared this in note format in Step 4 so it didn’t take long to put this presentation together. However, I did spend some time vocalizing the presentation and practicing it in front of my husband. At this stage I was not sure whether I would use the Powerpoint in the viva, or just use the slides as a way to guide the answer to this question. My supervisor suggested I should go with whichever I prefer, and I left that decision for closer to the time.

Step 6:  I placed bookmarks using post it notes in my thesis , across the top went Chapter numbers and across the side were key areas of my thesis, that I was pretty certain I may need to look at during my thesis (pages that had limitations of study for example, or why I had chosen one mode of survey over another for example).

Step 7: I had been compiling a list of new papers published since I had submitted that I thought I may be asked to comment about. I printed off the abstracts and read through them.   I also went back to the document prepared in Step 4, and read through it again critically and added more notes to it, and made some of the notes briefer. I also added a few notes to the thesis itself.

Step 8: I re-read the entire thesis for the second time before the mock viva (I suspect this probably wouldn’t be required if you do not have such a huge gap between submission and viva). I also practiced the presentation and took all my notes along to the mock viva

Step 9: The mock viva ended up being more of a chat than a mock viva. I received some good feedback on the presentation for the viva, and we discussed a few questions that may come up. One of the questions I hadn’t thought of was: Would your findings have implications on any other fields outside of healthcare? My supervisor also advised me that if both examiners asked me to make a change, or argued a point strongly, I should accept their advice and say “I’d be happy to make that change” rather than arguing with them.

Step 10: I updated the PPT based on feedback from my supervisor, and I went through the Q&A document, and highlighted the key questions that I needed to take as notes in the interview. I copied those questions and placed them on to 2 pages. I also placed some of the question and answers inside the thesis, and referenced it with page numbers on this 1 page (double page) notes document that I decided I would take into the thesis (parts of this double page notes document can be seen in the image at the top of this post).

Step 11: I re-read the entire thesis (for the third time) two weeks before the viva and typed up any typos/errors I found. I also updated the Double page notes document during this time.

Step 12 : In the final week, I practiced the presentation , practiced answering viva questions using the viva cards by myself and got my husband to ask me the questions too. I also read the thesis again (but this time missing some chapters). I printed off the PPT two days before and got all the things ready for the viva using my last-minute checklist (see below). The day before I went through the Thesis Defence Checklist and ensured it was all ticked off.

Step 13: On the day of the viva I got myself to the venue, had the viva and I passed with very few small minor corrections (8 to be precise). I have written about my viva experience in detail here .

Reflection post-viva:

In hindsight, I probably over prepared slightly, and the majority of the questions I had prepared for never came up. But the preparation gave me a huge amount of confidence, and it meant that I knew my thesis inside out, so during the viva I easily navigated to certain pages. If I had to go back I would probably use the 40 questions listed below to prep rather than the longer list of questions. I would definitely not skip the two mock vivas, and the PPT presentation I prepared, because presenting the PPT at very start of the viva meant that I started off very strong and was very well prepared for their initial few questions. (BTW I used printouts of the PPT to talk over the slides (I gave the examiners a copy too), rather than formally presenting the PPT visually using a digital screen).

[…] preparing for the viva. I have written about the 13 steps I took to prepare for the viva in detail here, so I will not go into that […]

Thank you very much for this post. I am preparing for my viva voce which will be on 20 Jan. When i re-read my thesis i felt overwhelmed by some parts of my thesis. But i will do my best and be prepared, so thank you for sharing this

it was useful

Thank you Salma for sharing your experiences in Viva Land. Much appreciated

Dear Dr.salma

Thank you for sharing your valuable viva experience , I will use your post as reference for preparing for my Viva next month , i have one question do think the 40 questions list is enough for viva preparation ( general questions)? Thank you !

Hi Munannad,

Personally I think the 40 questions as preparation is most likely sufficient as it covers most areas, and there’s only so much you can prepare anyways, as some questions will come that you did not anticipate. Do have a mock viva if you can. But don’t worry, you know your thesis inside out and can look into it too to find references or read passages.

All the best with your viva!

Best wishes, Salma

Thank you Dr Salma,

Reading through your viva experience has given so much confidence and structure. I will be having my viva voce PhD assessment in Mach 2020 and I am vigorously preparing for it with all my might. I have also just published an article based on my thesis. So, I thank you very much for sharing you experience, especially the 40 questions Best Wishes

Thank you. This is very useful post. Very thoughtful of you to have penned this so others find it helpful

Impressing the Examiners: How to Prepare for Your PhD Viva

May 27, 2020

So you’ve come to the end of your PhD studies and have submitted your thesis.

Now it is time to prepare for your PhD viva.

You might feel like everything you’ve worked for is riding on it, and in some ways, it is. But as long as you’re prepared, you should have no problem on the day.

In this blog post, we’ll discuss how to prepare for your PhD viva, as well as some PhD viva tips for how to handle it on the day.

Read on for more information.

Framing the Way You Think About Your PhD Viva

There aren’t many people with PhDs. While the number is certainly growing , you’ll be entering into an elite group.

You may think that your PhD viva is an exam where internal and external experts in your field will be waiting to trip you up and look for ways to sabotage you. That couldn’t be further from the truth.

Everyone there is rooting for you to succeed. They want to add another expert to their ranks, especially one who has something important and interesting to add to that field’s conversation.

Very rarely will you have someone on your panel who is trying to make you deliberately fail.

Think of it as a chance to talk about your work with fellow experts in your field. Often, they’re excited for the conversation they’ll be having with you about your work.

You can also think of it as an opportunity to show off what you’ve done to people who are where you might aspire to be.

Preparing for a Viva

After you’ve written and  submitted your thesis , it’s a good idea to take a break from it for a while. Focus on a hobby, read a few books not related to your thesis, or start a new project.

This clears your mind and allows you to look at your thesis with fresh eyes when you prepare for your viva.

Re-read your thesis before you go to your viva. It may sound silly, but you’ve been working on it for several years. Some of the arguments you’ve made may now seem a bit fuzzy to you, as you’ve been working on the minutiae of the chapters.

You need to make sure you remember the overarching theme of your thesis, as well as the arguments you’ve made in each chapter. Most examiners will allow you to bring in notes, and there will be a copy of your thesis for your referral. Don’t be afraid to make notes for yourself.

If you want to book a mock-viva with a real thesis examiner then get in touch. We run regular mock-vivas. 

Overall: familiarise yourself with the major themes in both the thesis as a whole but also in individual chapters.

Practise, Practise, Practise

Practise summing up the main points of your thesis. You’ll be asked about your major argument, as well as some of the minor arguments you’ve made within the thesis.

By now, you’ve likely already presented your thesis (or parts of it) at conferences, or discussed it at length with your advisor. If you’re worried about how well you’ll be able to do this, remember that you have done this previously.

You may even want to hold a practice viva where some of your friends or family members ask you about your research. You should be able to explain it in a way that is understandable to them, on some level. Obviously, they’re not experts in your field, but they should be able to have some grasp of what your thesis is about after explaining it to them.

Your PhD Thesis. On one page.

Anticipate the questions.

Speak to your advisor before you have your viva. Discuss with him or her some of the questions that may be asked beforehand. Or, you can ask your department, who may have a guide for PhD or MA students defending their theses. Or, you can look at the guide we’ve published . 

If you can anticipate the questions beforehand, you won’t feel as nervous when they’re asked. While they may ask you a few questions you won’t anticipate to ensure you’ve written the thesis yourself, you will still likely be able to rehearse the answers to the majority of their questions.

On the Day of the Viva

On the day of the viva, arrive early with plenty of time to spare. You may consider spending the night nearby if you live far away. Make sure you know where to go, and are properly fed and hydrated. You may wish to bring water with you to the viva itself. Re-read your notes and try to focus on relaxing. Don’t overthink it. 

Manage Your Expectations

Don’t expect to pass with zero corrections. This does happen but is usually very rare. You may hear of your colleagues doing this, and feel disappointed if you don’t.

Most people pass with minor or major corrections. Some people will be required to resubmit following very major revisions. This may seem like a huge blow, but remember that most people go on to resubmit their thesis successfully.

Very rarely do people not pass, or are awarded a lower degree because their thesis was not “good enough.” Your advisor has likely done a great job of helping shape your PhD, and you should expect that you will pass if you’re prepared, but likely with some form of corrections.

How to Prepare for Your PhD Viva

We hope this article answered your question of how to prepare for a PhD viva. Preparing for a viva can be nerve wracking, as it may feel as though the culmination of the past few years are all riding on this one moment. Remember, everyone is rooting for you to pass, even your examiners.

Viva examinations: guidance

This guidance explains the viva process, how to prepare, what will happen on the day and what the possible outcomes are.

This information is for postgraduate research students. It covers:

• before your viva
• preparing for your viva
• during your viva
• outcomes of the examination

Before your viva

Entry forms.

You must enter the exam via Portico about four months before you are ready to submit. You may not submit your thesis until you have entered for the examination and your examination may be delayed if you have not done this.  

Find out more about examination entry

Your supervisor is responsible for arranging the appointment of your examiners. This should be done at the same time as you complete your examination entry form, four months before you are due to submit your thesis. Examiners are appointed by UCL for their professional services as examiners with expert subject knowledge. A minimum of two examiners, one from outside UCL and (normally) one from UCL are appointed to co-examine all research degree candidates. The examiner nomination form can be found here .

Submit your thesis

Find out more about formatting, binding and submitting your thesis.

Collaborative research projects

If you are contributing to a collaborative research project you must include this information in the introduction to the thesis. You must clearly identify the demarcation between the research you are submitting for examination as an original contribution to knowledge and the work of your collaborators. 

Viva arrangements

Your supervisor (or nominee) will liaise with you and your examiners to arrange and confirm a mutually convenient time and place to hold the viva examination. The viva must not be arranged before the examiners are formally appointed by UCL. It may take place at UCL, or remotely. Your examiners should have your thesis at least six working weeks before the viva and you will receive an email once the thesis has been sent to the examiners. At this point, you will be able to record the viva via the ‘Research Student Administration’ section in Portico. A user guide is available with step-by-step instructions for submitting this information. Your viva should then take place within three months of the dispatch of the thesis to your examiners.

Download the viva notification user guide

Reasonable adjustments

If you or one of your examiners have a disability which UCL cannot accommodate, other reasonable arrangements can be made for the viva. You must make a request in writing when you complete the examination entry form to allow time for arrangements to be made. 

Preparing for your viva

We recommend that you re-read your thesis. Try to anticipate questions, comments and criticisms, and think how you would respond. Although you may not be able to anticipate actual questions to be asked by the examiners, this approach will encourage you to think actively about your work.   You should also refresh your memory of the relevant literature. Do not attempt to re-read every paper in the bibliography of your thesis; instead, re-read carefully some of the more recent key references. If you have left university after submitting your thesis you may be unaware of very recent work. Ask your supervisor a couple of weeks before the viva whether any work of direct relevance to your thesis has been published since you submitted your thesis.

You must not contact your examiners directly at any point leading up to the viva.  All contact should be done by your supervisor or other relevant departmental staff member.  

A good way to prepare for your viva is to practice. Your supervisor should give you a mock viva, or arrange for this to be undertaken by a member of your upgrade panel.  

Training to support writing your thesis and prepare for your viva 1) The Doctoral Skills Development Programme  has courses on formatting your thesis, tips on thesis writing and viva preparation. 2)   Academic English courses are available for doctoral students who want to enhance their academic writing and oral communication skills.  3) Arrange to speak with a digital skills trainer  who can answer specific questions, troubleshoot issues or point you to training courses or resources for self-study. They also have a thesis clinic that runs throughout July and August each year. 4) Your faculty and department may host their own workshops on writing a thesis. Contact your PGR administrator to find out.

During your viva

A viva is an academic interview at which your examiners will be looking for an understanding of the subject matter of your thesis, an appreciation of its significance to established knowledge in the field, and an awareness of the breadth of the subject area. 

Your supervisor will be invited to attend your viva examination, unless you request otherwise; you must indicate this on your examination entry form. Your supervisor does not have the right to participate in the viva examination but may contribute if invited to do so by the examiners.  

The examiners will expect you to:

• show a critical analysis of your own work and of that of others
• appreciate the limitations of the methods employed and the results obtained by yourself and others
• understand how the broad conclusions of your thesis support, add to or conflict with previous work
• know the major concepts and recent developments in your subject

There is no formal procedure laid down for the conduct of the viva examination. Some examiners prefer to work through the thesis in the order in which it is written. Other examiners prefer to discuss topics. Very few examiners will perform a page by page criticism. You may be asked to prepare a presentation of your work in a suitable format.  

You are not expected to know your thesis by heart, but to refer to the appropriate page when the examiners wish to discuss a specific point. Please ensure that you bring to the viva examination a copy of your thesis paginated in the same way as the copies you have submitted to the Research Degree Examinations Office.

You should not simply answer 'yes' or 'no' to questions nor give a prepared exposition. Try to answer the question as it is put, remembering that you are engaged in an academic conversation.

Be prepared to justify your ideas and conclusions. If the examiners challenge your interpretation but you feel that your case is a good one, muster your arguments and be willing to present your case firmly but courteously. However, if the examiners have identified a genuine weakness, concede the point gracefully. Even if you feel the examiners are unreasonably critical do not become argumentative or allow the discussion to become heated. You can agree to differ and to reconsider the point. All participants in the viva must abide by UCL's Bullying and Harassment Policy . If you make any comments to your examiners which put them under moral pressure, for example alluding to what will happen if they fail you, or if you offer any incentive to your examiners to pass you, they must terminate the examination and report to the Chair of the Research Degrees Committee via Research Degrees in Student and Registry Services.

Outcome of the examination

The following are the three most often received results and the subsequent procedures.

We will email you with reports from your examiners, copied to your supervisor, instructing you to submit the following documents:

• the electronic copy of your thesis 
• thesis deposit agreement form (uploaded with the e-thesis)

We will award your degree once you have met the academic conditions, the Library have confirmed receipt of your e-thesis and the Deposit Agreement form, and you have cleared any outstanding fees. 

The electronic copy of your thesis and thesis deposit agreement form should be deposited to the Library via UCL's Research Publications Service. Please make sure that you remove, or blank out, all personal identifiers such as signatures, addresses and telephone numbers from the e-thesis. Any photographs that you have taken should not show identifiable individuals without their permission and any you have taken of children should mask their faces. If you have any queries regarding this aspect of the process, please contact the Library directly.

UCL no longer requires a printed copy of your final thesis. If you do wish to deposit a hard copy you can do so by sending it directly to the Cataloguing & Metadata department of Library Services by post, or in person at the Main Library help desk.  You will find more information about the process on the existing webpage for e-thesis submission.

Once you have submitted these, we will send an email containing the confirmation of award and your reports to your email address you have recorded on Portico. The degree certificate will follow approximately four months after the official award date.

In the case of an examination for specialist doctorates (including the EngD, EdD and MPhilStud), the award of the degree is also conditional upon students passing all taught elements of their programme of study. The modules should be entered on to Portico by the Department and confirmation these elements have been completed will be passed from the Examinations Department to Research Degrees.

Minor corrections

This is by far the most common result received from the examiners. 

We will email you with reports from your examiners, copied to your supervisor and Faculty Graduate Tutor. The deadline to submit your corrections officially starts from the date of this email, which will also indicate the name of the person designated to check your corrections. This deadline is for you to submit the corrections to the designated checker, and not to submit the final copy of your thesis.

Your examiners may have returned an annotated copy of your thesis to you and therefore you may already be aware of the work required. The designated checker should inform you of the format he/she expects to receive the corrections, although normally this will be in electronic format.

The designated checker should confirm the outcome of the examination within one month of receipt of the minor corrections to the thesis. This is usually done by sending an email directly to Research Degrees.

Once this has been received we will follow the procedure for a pass result.

Resubmission in a revised form

We will email you with reports from your examiners, copied to your supervisor, Departmental Graduate Tutor and Faculty Graduate Tutor. The 12 or 18 month deadline officially starts from the date of this email.

Unlike the outcome for minor corrections, where one person checks the amendments, the resubmission requires you to re-enter for the examination and submit two copies of your thesis for forwarding to the examiners. 

Your examiners may have returned an annotated copy of your thesis to you and therefore you may already be aware of the work required. 

Once you have completed the corrections, you will need to:

• submit a new exam entry form to Research Degrees at least two weeks prior to the expected submission of the thesis
• submit an electronic copy of your thesis to Research Degrees via the UCL Dropbox.  

Find out more about formatting, binding and submitting your thesis. Your supervisor will be emailed to confirm that the examiners are still willing to act and provide their current contact details. This is to avoid the thesis from being sent out incorrectly. We will then send an email to your supervisor and examiners reconfirming their appointment and send the thesis to them via the UCL Dropbox.

If the examiners have requested a second viva, your supervisor will arrange this. In these circumstances, the procedure will follow that of a typical research degree examination.

If a further viva is not required, your examiners are only required to submit a joint report. They cannot award another 18 month resubmission, but can allow minor corrections.

Once the reports are received we will follow the procedure for either the pass or minor corrections result.

Other results

If the result falls outside the above descriptions, we will email you detailing the procedure you will need to follow.
