You need pressure to make diamonds. It’s cheesy, but maybe you need the pressure of viva questions to find certain insights. I’ve lost track of the number of times someone has told me that they found new ideas through talking to their examiners. Sometimes a new connection or way of explaining something.
Viva pressure can produce amazing results, but it can seem overwhelming, particularly as the day draws near. If you feel nervous or anxious, remember that you also need time to make diamonds. Viva questions might seem pressured sometimes, but you can take time to answer them. There is no need to rush to respond. Listen to the question, think about it, make a note: you don’t have to have the whole answer when you start to speak. Start, and see where the discussion goes.
