It’s essential to read the regulations for thesis examination at your institution before you submit. They’ll tell you what you need to do and what you need to know. Some of this you’ll have picked up by being around other postgraduate researchers for years, but there can be key points you have missed.
Check for details on timelines. Check for paperwork you need to complete. Check, if needed, what the requirements are for having a viva over video.
Remember that reading the regulations is only a small part of the story. They won’t tell you what questions will come up. They won’t tell you what you need to do to get ready. They won’t tell you what vivas are really like.
So ask your friends and colleagues. Talk with your supervisor. Read blog posts and viva stories to get a sense of what to expect. Explore whether or not there are norms within your department for how vivas take place.
And when your viva is finished and you’ve passed, consider sharing your experience to help shape the expectations of other candidates. They’ll read the regulations too, but will need your story to help guide their expectations, preparation and confidence.
