There are lots of big picture questions that seem natural for the viva.

  • “Why did you choose this topic?”
  • “How do you describe your main contribution?”
  • “How would you summarise your thesis?”

These aren’t unexpected questions exactly; you’ve probably thought about them during your PhD. Another question that shows up on lists of common viva questions is “Why do you deserve a PhD?” I’m not sure how common this question actually is, but at first glance, answering it could be a little trickier than the other questions mentioned so far.

“Why do you deserve it?” Deserve. You could look at this question and wonder if it is a trick or not. Are your examiners trying to trap you somehow? It feels a little like a trap…

Or perhaps we can find a similar question that makes it easier to answer. Perhaps, “What have you done that merits a PhD?” or “What have you done to achieve a PhD?” That’s what we’re really getting at. And when you look at that phrasing, actually we’re not far away from “How do you describe your main contribution?”

The work, the result, the outcome, the contribution, the talent, the knowledge – all of these are because of what you’ve done. They’re what you’ve achieved, they’re why you deserve a PhD. It may feel uncomfortable to think about why you deserve something…

…so get comfortable with it. Not in a proud or boastful way, but in an honest sense of your own accomplishments. Explore how you would describe what you’ve done, and you’ll find a way to talk to your examiners about your contribution: something that merits your PhD.

You might just start to believe it yourself!
