Read your examiners’ recent publications to check that you know how or if their work connects to yours. Find out what they are interested in and what you know about those topics.
Read your thesis and be certain of what you’ve presented: the details, the numbers, the quotes and how it all fits together.
Reflect on your journey and know what that means for you: who you are, what you know and what you can do.
Knowing all of this well help for the viva – and doing all of this is not a hard set of tasks to complete.
