Take twenty minutes to write down keywords for each question to capture ideas of what you might say in response.
Take thirty minutes to sit, think and maybe write about what this is telling you.

Flip that feeling. What do you want to be asked?
Or, perhaps when you reflect, what do you want to share with your examiners? What would you say? And what does that mean?
