Be aware that there’s a chance your viva won’t be amazing.
It’s likely it won’t be terrible or exhausting. It’s highly improbable for your examiners to be unprofessional or unfair. And it’s certainly true that the viva can be an enjoyable experience.
But it could be just OK.
I’m glad that lots of candidates enjoy their viva. I’m sad that some people, like me, feel their viva is an anticlimax. I don’t know what can be done to set expectations for the emotional experience that candidates might have.
At the very least consider it as a possibility.
There’s a good chance you will enjoy your viva! It’s unlikely you will hate it. But it could end up just OK.
Still, you’ll have passed. Then you can move on to the next step of your journey.
