A question that’s expected can be prepared for.
A question you expect can still be difficult to respond to.
If you expect a question you might not be asked it after all.
And if you prepare you may still find something new to say on the day of your viva.
Remember that rehearsal for the viva doesn’t mean memorising talking points on expected questions. Rehearsal helps you find a process to engage with all questions about your research, your thesis and you – expected and unexpected.
