I read through my thesis about 3 weeks before the viva, summarising it in the way Tinkler & Jackson recommend, so I engaged with it a bit more actively. I'm a *very* slow reader BTW (due to brain damage and serious illness) so had to take ages to work through this stage!
I didn't bother with long lists of potential viva questions. Instead I focused on 5 things:
- originality
- contribution to knowledge
- methodology
- weaknesses, gaps and mistakes
- what would do differently if starting again
I figured by sorting out those in my head I'd be ready for most general questions.
