How long will your viva be?
What will your examiners think about your thesis?
What questions will they ask?
What award will you get?
How will you feel afterwards?
How long will it take to complete corrections?
You might have expectations, but some questions about your viva have answers that are unknowable at this point.
So focus on what you do know.
Your viva comes at the end of several years of hard work. You did the work. You are talented. You’re more than up to the challenge.
