You’ll most likely pass your viva!
It really is the most likely outcome.
Which doesn’t mean you shouldn’t be nervous. It doesn’t mean that there’s nothing to prepare for or you can just take time off until you meet your examiners. And it doesn’t mean that you won’t be challenged by your viva, the preparation, the corrections or anything connected with it.
You’ll most likely pass your viva. Do the work to fulfil that. Be nervous, but work to get ready and be confident. You’ll be challenged, so work to meet that challenge and respond to your examiners’ questions.
Spoiler alert: you’ve got this.
