Common Viva Questions by Category
You can't predict every question, but you can prepare for the types of questions that almost always come up.
How to Conduct a Mock Viva
A well-run mock viva is the single best preparation strategy. Here's how to do it right.
Arrange Mock Viva
Schedule 2-3 weeks before actual viva. Ask supervisor plus one other academic (ideally from different field). Allow 1.5-2 hours.
Prepare Materials
Give mock examiners your thesis at least 1 week before. Provide examiner names/backgrounds if known. Prepare as you would for real viva.
Simulate Conditions
Use a formal setting. No interruptions. Practice opening statement. Have examiners role-play challenging questions.
Get Feedback
After the mock, get detailed feedback on: content, presentation style, handling difficult questions, areas of weakness.
Review and Adjust
Identify gaps in your preparation. Practice weak areas. Don't just practice answers—practice thinking on your feet.

Pass (No Corrections)
Rare (5-10%)Thesis is accepted as submitted. You're done!
Minor Corrections
Most Common (60-70%)Small changes required: typos, clarifications, minor additions. Typically 1-3 months to complete.
Major Corrections
Common (15-25%)Significant revisions required: rewriting sections, additional analysis, strengthening arguments. Usually 6-12 months.
Revise and Resubmit
Less Common (5-10%)Major work needed. Full thesis resubmission with second viva. 12-18 months typical.
MPhil Award
Rare (1-3%)Work doesn't meet PhD standard but merits Master's. No resubmission option for PhD.
Fail
Very Rare (<1%)Thesis fails to meet requirements with no opportunity for revision.
On the Day: Essential Advice
Arrive Early
15-20 minutes minimum. Use waiting time to settle, not panic.
Bring Essentials
Annotated thesis, summary notes, water, tissues, any medication you need.
Opening Mindset
You are the world expert on your thesis. The examiners want to have an intellectual discussion, not an interrogation.
Listen Carefully
Make sure you understand each question before answering. It's okay to ask for clarification.
Think Before Speaking
Silence while you gather thoughts is better than rambling. Take your time.
Acknowledge Limits
It's fine to say 'I hadn't considered that, but my instinct is...' or 'That's beyond the scope of this study, but...'
If You Don't Know
Say so honestly. 'I don't have a definitive answer to that, but here's how I might approach it...'
Stay Composed
Challenging questions are normal and expected. They're not attacks; they're intellectual engagement.
