Preparing for Your Thesis Defence: What Examiners Actually Ask

A thesis viva rarely tests whether you can recite your thesis — it tests whether you understand it well enough to defend decisions you made months ago. Preparing for the right categories of questions matters more than re-reading the document cover to cover.

“Why this method, and not another?”

Examiners frequently probe methodology choices specifically to see if you understand the alternatives you didn’t choose. Be ready to name at least one alternative method and explain why yours fit your research questions better.

“What would you do differently?”

This question isn’t a trap — it’s standard, and a thoughtful answer signals critical distance from your own work. Have two or three genuine limitations ready, along with how you’d address them with more time or resources.

“How does this connect to the wider field?”

Examiners want to see you can place your specific findings in the context of the broader literature, not just recite your own results. Revisit your literature review the night before and rehearse a two-minute summary of where your work fits.

“Walk me through this specific result.”

Be ready to explain any table or figure in your results chapter without notes — including what test was used, why, and what the specific numbers mean in plain language, not just “it was significant.”

“What’s the practical or theoretical contribution?”

Have a clear, one-paragraph answer ready for what your research actually adds — a new context, a new method, a new theoretical link — distinct from “no one had researched this before.”

Practice out loud, not just in your head

Rehearsing an answer silently and saying it out loud under time pressure are different skills. A mock session with pointed follow-up questions exposes gaps a solo read-through won’t.

Our thesis defence preparation sessions run exactly this format — a question bank specific to your thesis, followed by coached answers under realistic conditions.
