Expecting the Unexpected
It’s right to learn about viva expectations. Get a sense of what vivas are generally like, read the regulations, listen to the stories of your friends to build a picture for what your viva could be like. Get a sense of what to expect.
And expect that yours will not follow that plan at all.
You won’t get the same questions. It might not be the same length. You won’t get the same corrections. You might not get the same first question and you won’t face the same challenges.
There’s no contradiction. Vivas are unique, but not unknown or unknowable. Vivas have structures and follow patterns, but never repeat. Expect that yours will be similar to many others. Expect that yours will be different in ways you can’t predict.
And expect yourself to be ready for whatever you’re asked.
