As part of your viva prep spend ten minutes listing everything you’d like your examiners to ask.
Reflect for each one: why do you want them to ask about that thing?
Do you feel confident? Why?
Do you feel happy? Why?
Do you feel proud? Why?
It’s useful to dig into things that trouble you and ask why. Once you’ve unpicked the feeling you can start to do something about it.
It’s just as useful to reflect on the things you’re happy with. You can build confidence for the viva on those whys as well.
