Preferences
Your preferences for the viva matter.
They can have an impact on how you engage with the viva and with what happens there. Some preferences can be met much more easily than others. And if some aren’t met you will have to decide what to do regardless.
Your preferences for viva prep are probably the most easy to meet: if you need to prepare at a certain time in a certain way or use particular materials to annotate your thesis that’s not so hard to do. You might have preferences around rehearsal – a mock viva date or help from particular friends – and these could be trickier, but not hard.
Preferences for examiner selection are just that: you can prefer certain people but have no direct control over their nomination or acceptance. Supervisors might ask candidates for ideas, but ultimately they have to select who they think will be a good choice. Academics asked to be examiners have to weigh up their other work and responsibilities. You might really want someone or an academic with a certain kind of background but ultimately your preference could be unsatisfied.
You might prefer a 90-minute viva or one that begins with a particular question. You might prefer to feel a certain way or to know in advance what the outcome will be. And you might prefer that you didn’t have a viva at all! But you can’t really control any of these things. There are things you might prefer and then the reality of what happens: some of your preferences might be met and some might not.
So what does all of this mean?
First, again, your preferences matter. It will probably help your general viva readiness to be aware of and fulfil your preferences as much as you can.
Second, you have to work past any emotional friction you feel from preferences that can’t be met. That might not be easy but there isn’t anything else to do.
