After years of work it could feel odd to be talking about your research in your viva.
Perhaps if you’ve had a break between submission and the viva, things might feel a bit rusty when you think or talk about your work.
Or if your viva has to be over video it could feel awkward if there are delays, nervous moments waiting silently to get a response.
It might be weird to have unexpected questions, or be weird in advance trying to figure out what questions you might be asked by your examiners.
There’s plenty of space for weird around the viva, but remember: weird doesn’t mean bad. Even if your viva is a little unexpected, a little strange or a bit weird, it will still most likely be absolutely fine.
