What could your viva be like? It could be lots of things!
It could be four hours long but feel like it’s over in half that, like mine felt to me. It could begin with a chance for you to summarise what you’ve done or with an open question from one of your examiners. It could be that you are sat around a seminar room table with your examiners or that you’re talking to each other over video and at a great distance.
There’s a lot of variety to the viva. When you account for all of the weird one-in-a-million cases, like someone (me) standing for their four hour viva, the chief expectation for vivas is that they are good.
Expect your viva to be good. Expect your thesis to be well-received. Expect your examiners to be good and prepared. Expect that you’ll receive good questions.
Expect yourself to be good enough.
