Are you going to spread out your viva prep over weeks or months, or do it all in a few days leading up to the viva?
Are you going to explore possibilities for your examiners in conversation with your supervisors, or leave the choice purely to them?
Are you going to be ready for your viva, or simply optimistic?
Are you going to respond to any and every question in the viva, or have questions in mind that you’d rather not discuss?
Are you open to being wrong about something, or certain that your research is right?
Some choices for the viva are easy, others aren’t. Some you have to make once, some you have to repeat. Some are conscious, some you won’t notice. Some have deadlines, some are fixed, and some you can change.
But they are there. They are your choices that lead you to the viva you’ll have and how you’ll engage with it.
