They do.
Slips, errors, accidents, typos, absent-minded actions and more. There’s a worry for some candidates that examiners will not forgive mistakes. Perfection is not the standard for the thesis or the viva, but you can still wonder, “What will they think about X?”
Well, let’s assume that whenever you find out about X you can’t do anything to change it (because otherwise, you probably would and it wouldn’t be a worry). Maybe you know X happened while writing up; maybe you discover X when you’re preparing for the viva; perhaps you’re asked and only realise X in the viva. Essentially your next steps in all these cases are the same.
Simply think about the Why, How and What of the mistake:
- Why did the mistake happen?
- How could you do something about it?
- What do you think you need to do about it now?
Mistakes happen, and sometimes you need to act to correct them. Sometimes you just need to acknowledge them. Reflect on the why, the how and the what to explore how you might respond to examiners’ questions about mistakes in the viva.
