You don’t get to choose your examiners. You might be asked for your opinion but ultimately, your supervisors will decide. They have the responsibility of nominating the two people who will examiner your thesis and convene your viva.
You don’t get to choose – but you might be able to steer the selection. You can put names forward, and it’s worth doing so. If your supervisors already have a good idea then ask them to share that with you. Ask them to explain why these choices are good ones for you; not to dissuade them but to build your confidence that they are the best choices for your viva.
You don’t get to choose. When your examiners are selected you can always find out more about them. You can be certain they are good candidates – in the same way that you are a good candidate. You can learn about them to get a sense of their perspective.
You don’t get to choose but that doesn’t have a big impact on how ready you will be to talk with them on viva day.
