To organise your viva prep think about what you want to do and what you won’t do.
You want to read your thesis but you won’t obsessively re-read it.
You want to make a note of typos but you won’t go looking for them.
You want to know about your examiners but you won’t read every paper they’ve ever published.
You want to feel ready for your viva but you won’t over-invest your time.
You want to respond well to questions in the viva but you won’t do that by scripting lots of responses in advance.
You want to feel confident but you probably won’t be able to eliminate nerves completely.
You want to do well in your viva. You won’t have to do much in preparation for that outcome.
