Examiners Are Not The Enemy Either
They’re not out to get you, with malicious ideas and opinions. You’re not locked in their sights, and they’re not on a mission to make the viva uncomfortable, unenjoyable and un-passable.
They have to do their job. They have to examine your thesis and you. They have to be experienced and knowledgeable, they have to be prepared for the viva. That can sound intimidating, but all of these are good things.
Remember that you’re the expert in your thesis. Your examiners might have more general experience than you, but no-one else in the world has as much experience with your work as you do.
Your examiners are not faceless and unknown. See what you can learn about them and their work. Explore what you can find that will help you feel confident meeting them to discuss your research.
