A thesis needs to contain a significant, original contribution. A viva needs to have some exploration of this. So in preparation for the viva’s discussion, it makes sense to spend some time reflecting and exploring these factors.
- Why is your work valuable?
- Who is it valuable to?
- How would you describe the importance of your research?
- What makes it special?
- What makes it matter?
- What aspects are novel?
- In what ways is your work different?
- What exists now that didn’t before?
- How does your work change your field?
- How can you qualify the originality?
Not every useful viva prep question is typical of a question you might get in the viva. Not every question might prompt an answer for you. Some answers might overlap. The point is to get thinking and writing and see where this leads you.
