MSc Viva Questions: What Master's Examiners Ask and Why
The MSc viva questions examiners ask, grouped by what they test, with real formats from Oxford, Anna University and UTM, a calibrated sample answer and a prep sheet.
MSc viva questions test whether you understood and can defend the research you actually did. Examiners ask why your question matters, why your method fits it, what your results show and where they stop. The safest answers keep each claim the size of a master's project: well applied, soundly judged and clearly explained.
Claim size matters, because a claim pitched at doctoral size invites doctoral-size follow-ups. For a full side-by-side of the two exams, see how a master's viva differs from a PhD viva.
Where MSc vivas are used and what they look like
Not every master's degree has a viva, and the rules differ by university, programme and country. The examples below come from each university's own published rules. Read your own handbook before you trust any general advice, including this page.
| University | Degree | Who examines | What the rules say |
|---|---|---|---|
| University of Oxford, UK | MSc by Research | Internal and external examiners | The research examinations page covers the MSc by Research. The internal examiner should contact you within four weeks of receiving your thesis to arrange the viva. |
| Anna University, India | M.Sc. (5 years) project work | A team of the supervisor and an internal examiner other than the supervisor, plus an external examiner | The 2023 M.Sc. (5 years) regulations base the project evaluation on the report, followed by a viva-voce (clause 10.4.4). |
| Universiti Teknologi Malaysia | PhD and Master by Research | Chairperson, external and internal examiners; supervisors present | UTM's policy and guidelines page lists an online viva procedure for Master by Research. Its guide for chairpersons says the candidate should present for no longer than 20 minutes. |
Two details from these rules change how you prepare. At UTM, the chairpersons' guide says supervisors generally do not speak unless the chair allows it, so you answer alone. At Oxford, the research examinations page asks you to take a copy of your thesis to the viva, in print or digital form.
Questions to ask your department before the viva
If you study somewhere not listed here, such as Nepal, Bangladesh or another Indian university, ask for the written rules. Five questions cover most of what you need:
- Who examines me, and is my supervisor in the room?
- Do I give a presentation first, and how long is it?
- Is the viva marked separately, or does it confirm the thesis mark?
- Can I bring my thesis and notes?
- What outcomes are possible, and how long do I get for corrections?
The MSc viva questions examiners ask, grouped by what they test
The most useful way to group MSc viva questions is by the skill each one checks. The six groups below follow the order a viva tends to move in, from explaining the project to judging it. Your examiners may mix them, so prepare every group.
Can you explain your work clearly
These questions come first because they set the tone. They check that you can say what you did in plain words, to a specialist and to an outsider.
- Summarise your project in two minutes.
- What was your research question, in one sentence?
- Why did you choose this topic?
- Explain your main finding to someone outside your field.
A strong answer names the question, the method and the result in that order. It does not start with the background reading.
Do you know the field you worked in
Examiners check that your reading was more than a list. They want to hear which work shaped your study and where you stand in a live debate.
- Which three sources shaped your study most, and why those?
- What debate does your project sit inside?
- Which author do you disagree with, and on what point?
- Has anything relevant been published since you started?
A strong answer names an author and a specific claim. "The literature suggests" is not an answer.
Can you defend your method
This is where you should expect real time to go, so prepare the hardest version of each question. Examiners want to know you chose the method, rather than inherited it.
- Why this method rather than the obvious alternative?
- How did you choose your sample, participants or data?
- How did you check that your measures or codes were sound?
- What ethical approval did you need, and what did it change?
- If you started again, what would you change about the design?
A strong answer admits one real weakness and explains why the choice was still reasonable. For more depth, the 45 common viva questions guide explains why examiners ask each methods question.
Can you judge your results fairly
Examiners test this by pointing at a table or quote and asking what it does not show. The skill is judgement when the data are incomplete or messy.
- Walk us through the result on page X.
- What else could explain this result?
- How confident are you in it, and why?
- What would you do about the missing or messy data?
What did you add
At master's level, the honest answer is usually about applying a method or theory well in a new setting. So keep your claim the right size.
- What is new about how you applied this method or theory?
- Who could use your findings, and for what?
- What does your project add, in one sentence?
Did you work independently
Examiners want to hear which decisions were yours. Have one concrete problem ready that you solved without being told how.
- What problem came up that you solved yourself?
- Which design decision are you proudest of, and why?
- What would the next study after yours look like?
Project and technical vivas
Engineering, computing and science projects add practical questions about the build. Expect to be asked why you chose an algorithm, tool or instrument, and to show it working. The project viva questions guide groups these by project type.
How to answer MSc viva questions at the right level
Answer in three moves: your point, the page that supports it, and the limit you accept. This keeps answers short and keeps your claims at master's size. Overclaiming is the mistake to avoid, because a larger claim invites a harder follow-up.
Here is an illustration. Imagine a master's study that surveyed nursing students about a revision app.
Examiner: What does your study show?
Overclaimed answer: It shows the app improves exam results for nursing students.
Calibrated answer: It shows that students in my sample who used the app more often reported feeling better prepared, on page 41. It cannot show the app caused better results, because I measured self-report at one point in time. A follow-up study would need exam marks.
The calibrated answer is longer, but it closes the door on the follow-up instead of opening it. It also shows the examiner you know exactly what your data can carry.
Are masters viva questions easier than PhD questions
They are not easier, but they are pitched at a different claim. A PhD viva asks you to defend an original contribution. An MSc viva asks you to show that you applied methods well and judged your results soundly.
A one-page MSc viva prep sheet
Fill this in the week before your viva. One row per likely question is enough, and ten rows will cover the groups above.
| Likely question | My answer in two sentences | Page | The limit I will admit |
|---|---|---|---|
| Why this method? | |||
| What does your main result show? | |||
| What else could explain it? | |||
| What would you change? | |||
| What does your project add? |
Say each answer out loud once. If you cannot find the page in under a minute, add a sticky tab to your copy of the thesis.
If you face a master's thesis defense in the US
In the US, the equivalent exam is called a master's thesis defense, and a committee asks the questions. Canada spells it "defence", as on the University of Waterloo's thesis page. The committee format changes who asks what, and the US guide to master's thesis defense questions covers committee roles and named graduate school rules.
What Thesisroom does with this
Thesisroom's Defense Practice writes questions an examiner could ask, each tied to a specific passage or page of your own thesis. You can answer in writing or out loud. It offers three styles: Practice, Rapid round and Mock panel. It does not write your answers or give you a script.
Before analysis, Thesisroom removes your name, email, phone numbers, student ID, title page, declaration and acknowledgements. The privacy page explains how this works.
Frequently asked questions
What questions are asked in an MSc viva?
Expect questions on your research question, why you chose your method, what your results show, what else could explain them, and what your project adds. Examiners also check your reading and which decisions were yours.
How long is an MSc viva?
It depends on the university. UTM's guide for chairing online oral examinations says the candidate should present for no longer than 20 minutes before questions. Check your own handbook for the full length, because published rules differ.
Do all MSc degrees have a viva?
No. It depends on the programme and university. Oxford's research examinations guidance covers the MSc by Research, and Anna University's M.Sc. project work ends in a viva-voce. Your programme handbook is the only reliable answer.
Can my supervisor attend my MSc viva?
Sometimes. Anna University's M.Sc. (5 years) regulations put the supervisor on the viva team. UTM's chairpersons' guide lists supervisors as present but says they generally do not speak unless the chair allows it. Other universities differ, so ask your department.
Is the MSc viva harder than the PhD viva?
It is pitched at a different level. A PhD viva tests an original contribution, while an MSc viva focuses on method, judgement and clear explanation. Keep your claims the size of your project and you remove the hardest follow-ups.
How do I prepare for MSc viva questions in a week?
Fill in a one-page prep sheet with ten likely questions, a two-sentence answer and a page number for each. Say every answer aloud once. Tab the pages you cite, and practise admitting one limit per answer.
