Cambridge MPhil Viva - what to expect?!

I have an MPhil viva coming up and I genuinely don't know what to expect, my supervisor's told me that the MPhil viva is easy compared to the PhD one and that I should just re-read my thesis. But I was hoping someone on here has done the Viva and can give me tips, tell me what sort of questions the examiners asked, and how long/difficult their viva was. My deparment was the Engineering department, but I'd be happy to hear from other subjects too! Thanks!

Yup, you just need to read it through so you remember what you said. You will get questions on why you used certain techniques and materials versus other materials, did you read/consider so and so's work and if so, why didn't you use it etc. They aren't trying to catch you out, and they aren't asking because you are wrong. Viva's for MPhils are for benchmarking, proving no contract writing, ie you wrote the paper (not that that is suspected, just carrying out a viva process ensures people don't risk paying for someone else to do the work), and sometimes for marginal grades where if you talk about it well, you can go up a grade (but never down).

All you need to do is defend why you wrote what you wrote. There are no traps.

Thanks, this is reassuring, also did you have to prepare a presentation for your viva?
