How to Prepare for Your Viva: Questions, Strategy and What Examiners Look For

By Swift Academic Services · Updated 4 August 2026 · 8 min read

The viva is not an interrogation designed to catch you out. It is a conversation in which you demonstrate that the thesis is genuinely yours, that you understand its choices, and that you can defend them. Preparation is mostly about re-familiarisation and framing, not memorisation.

What examiners are actually assessing

Examiners typically want to establish four things:

  1. That the work is your own and you understand it deeply
  2. That your methodological choices were reasoned, not accidental
  3. That you know where your work sits in the wider field
  4. That you can recognise the limitations of your own study
Nobody expects a flawless thesis. Examiners expect you to know where the weaknesses are and be able to discuss them intelligently.

Re-read your thesis like an examiner

Read the full thesis at least twice in the weeks before. On the second pass, annotate as a critic would:

  • Where is the argument weakest?
  • Which choice would I most likely challenge?
  • Where does the evidence not fully support the claim?
  • What obvious alternative approach did I not take, and why?

Prepare an honest answer for each. Anticipating a challenge is far more impressive than being surprised by it.

Questions you will almost certainly face

  • Summarise your thesis in a few minutes.
  • What is your original contribution to knowledge?
  • Why did you choose this topic?
  • Why this methodology rather than an alternative?
  • What were the main limitations, and how did they affect your conclusions?
  • Which finding surprised you most?
  • How does your work relate to [key author in your field]?
  • What would you do differently if you started again?
  • What are the practical implications of your findings?
  • Where would you take this research next?

Prepare a two-minute and a ten-minute version of your summary. You will likely be asked for the short one first.

How to answer well

DoAvoid
Pause and think before answeringRushing to fill silence
Ask for clarification if a question is unclearGuessing what was meant
Concede a fair point, then explain your reasoningDefending every point rigidly
Refer to specific pages, tables or chaptersSpeaking only in generalities
Say “I do not know, but here is how I would find out”Inventing an answer

Conceding a genuine limitation demonstrates scholarly maturity. Refusing to concede anything tends to read as defensiveness or lack of insight.

Practical preparation in the final weeks

  1. Arrange a mock viva with your supervisor or peers
  2. Prepare a one-page summary: aim, question, method, key findings, contribution
  3. Tab or bookmark key pages, tables and figures for quick reference
  4. Re-read the two or three most influential papers in your field, and any work by your examiners
  5. Prepare a short list of corrections you have already identified yourself
  6. Confirm format, duration and who will attend

Knowing your examiners published positions is genuinely useful – questions often reflect their own research interests.

Understanding the possible outcomes

  • Pass with no corrections – rare
  • Pass with minor corrections – the most common outcome, typically weeks to complete
  • Pass with major corrections – substantive revisions, usually months
  • Revise and resubmit – significant rework, followed by re-examination
  • Award of a lower degree, or fail – uncommon where supervisors approved submission

Minor corrections are normal and are not a sign of weak work. Most successful candidates receive them.

Key takeaways
  • Examiners test understanding and reasoning, not perfection
  • Prepare two-minute and ten-minute summaries of your thesis
  • Know your own limitations before they are raised
  • Conceding a fair point shows maturity, not weakness
  • Minor corrections are the normal outcome

Frequently Asked Questions

How long does a viva last?
Most vivas run between one and three hours, though this varies by institution and discipline. Two hours is a common average for a PhD examination.
Can I take my thesis into the viva?
Yes, in almost all cases you are expected to. Bring an annotated copy with tabs marking key sections, tables and figures so you can refer to specifics quickly.
What if I cannot answer a question?
Say so honestly, then show your reasoning: explain how you would approach finding the answer, or what evidence would be needed. Examiners respect this far more than a fabricated response.
Should I memorise my thesis?
No. You need deep familiarity, not memorisation. Know your argument, your methodological reasoning and where key content sits, rather than reciting text.
Is it normal to get corrections?
Yes. Minor corrections are the most common outcome for successful candidates and reflect normal academic scrutiny rather than any failure.
