The mock viva is generally valuable because of the kind of practice it provides. Your supervisors might have some clear ideas about what a mock should be like. But if you think about it, the mock is a sort of test run for later success.
So think: what do you need to succeed?
- Are you looking for certain types of questions or a particular focus for the discussion?
- Do you want practice or pressure?
- What kind of feedback would be most useful from the experience?
Think about what might help you. Everyone has different needs. It’s not wrong to think about how you can make the most of the opportunity.
