There are lots of reasons. Any one of the following might be enough:
- You did the work.
- You’re talented.
- Your examiners are there to examine, not interrogate.
- Vivas have expectations.
- Examiners have responsibilities.
- You can prepare for the viva…
- …and you will have prepared for your viva. (right?!)
- The viva isn’t a total mystery.
- Of the three people in the room, you have the expertise when it comes to your thesis.
- You have a history of rising to meet challenges.
Taken in combination, they paint an impressive picture for the outcome of your viva.
There are many more reasons you will pass your viva, specific to you, your thesis and your research journey. The many reasons you’ll pass align with reasons you could be confident about your performance in the viva.
You’ve not got this far by accident; you’ve not got this far by only showing up.
