The verb that could most clearly summarise what you have to do at the viva is demonstrate. Your examiners have read your thesis. Now they need you to give them more in the viva.
- You have to share what you know and what you can do.
- You have to clearly describe and explain what you did for the last few years.
- You have to show just how good you are as a researcher.
In the viva you’re giving a demonstration of how much you’ve done and how good you are. Your thesis counts towards your success, but you have to be ready on viva day to demonstrate just how capable you are.
