If your supervisor offers you can say no. You don’t need to ask for one. You can just leave it be.
Of course, most people who have one find it useful, but you don’t have to have one. It’s not a viva pre-requisite. If you’re busy, or you already feel ready, or you just think there’s something else you could be doing instead that will help more, then don’t have one.
But if you’re worried then think twice. Think back to Monday’s post and explore for yourself: Why are you worried about having a mock viva? What’s at the root of that worry?
You can still say no to the mock if you’re worried, I’m not advising you go ahead with it – but you should probably do something about the worry.
There are lots of good reasons to have a mock, and plenty of reasons you might not want to. Make sure you focus on the right reasons either way.
