A Different Perspective

It would be great to know what your examiners think about your thesis. So awesome to know what questions they’re going to ask. Probably a relief to know what the viva is going to be exactly like.

But.

You can’t ask your examiners for help. You can’t know what questions they will ask. You can’t know how they will go about running the viva.

But.

You have a supervisor. You may have more than one. All of them have PhDs. They probably act as examiners too. So ask them questions.

Ask them what they do when they read a thesis. Ask them if there are any questions that they always have in mind. Ask them what they would want to know about your research.

You can’t know your examiners’ perspective in advance. But you can get your supervisors’ thoughts: not the same, but they’ll come from experience and will be valuable.

Nevermind

I didn’t listen to Nevermind by Nirvana when it came out. I was in my teens in the 90s, but for some reason the album never connected with me. Of course, I heard Smells Like Teen Spirit but it just sounded loud and angry. I didn’t get it.

In my thesis I wrote a really detailed explanation of how I produced a particular algorithm. I walked the reader through it step by step. And it didn’t connect with my examiners. They thought it read like a story. They didn’t get it.

In both cases though, there was an opportunity to correct. In my viva I was able to explain the process, and my examiners got it. They asked me to re-write my explanation, but they understood what I was trying to get across: my thesis was better as a result.

And last month I listened to Nevermind for the first time: life is better as a result.

Expect Unique

If you ask around about viva length, two to three hours is fairly common. If you google you’ll find lots of lists of standard questions. On the day you will probably find out the result within thirty minutes of the end. (and you’ll probably get minor corrections)

There are broad expectations for the format and tone of the viva. But you can also expect that yours will be unlike anyone elses. My viva was four hours long and I was stood for the entire viva in front of a blackboard. I didn’t expect that and I don’t expect it for your viva! I started stood up giving a short presentation, and things just went from there.

Ask your friends who have had vivas recently what they were like. See if there are common experiences but know that yours will be a custom experience to examine you and your work.

What If I Fail?

Why might I fail? What happens if I fail? What is the process for failing the viva like?

I am asked questions like this all the time. Some people do fail the viva. The vast majority don’t.

What makes you think you would?

If you’re thinking about failure, seriously thinking about failure… Why? What has tripped that thought for you? There’s a real difference between wanting to pass and thinking you might fail. If you’re concerned about your examiners, read some of their papers, ask around about them. If you’re worried about remembering “everything” then read your thesis carefully and make some notes. If you worry about answering questions under pressure then have a mock viva, or get friends to practise with you.

If you’re really troubled by the thought of failure, do something about it.

Breaks

A very practical post today that springs from a frequent question at workshops: “Can I take a break in the viva?

Yes. Yes. Yes. Yes. Yes. Yes.

Yes.

Bathroom break, leg stretch, medical need – you can ask for a break in the viva. As time progresses, your examiners should be thinking about whether or not it is appropriate to offer a break. Most vivas fall in the two- to three-hour range. That’s enough time that a short break is in order.

If you need one, ask. If you’re offered one, say yes, move about and get some blood flowing.

Spoilers

For years I’ve avoided spoilers. I remember racing home with the final three Harry Potter books on the days they were released, turning my phone off and reading until they were done – partly because I was desperate to know what happened, but also because I didn’t want anyone else to spoil them for me.

Spoiler Alert! A small number of vivas start with examiners telling the candidate that they’ve passed. Some examiners do it to reassure the candidate. Examiners who declare a pass at the start have good intentions, but universities would prefer examiners didn’t do it. It begs the question, “Is this an exam or not?”

After I’ve shared this possibility in workshops – usually because someone has said, “A friend of a friend was told they’d passed…” – I have to add that it’s not that likely and if it were your viva you would never know until it happens. You could spend all the time on the run up to the viva thinking, “Will they tell me at the start? Will they tell me at the start?” Is that helpful? I don’t think so.

You can’t control what your examiners will do in the viva or at the start.

Spoiler Alert! You can control what you do and how well you can be prepared.

Hours and Years

Two to three hours is pretty standard for a viva. Sometimes less, sometimes more. Two to three hours is the right neighbourhood.

Three to four years is pretty standard for a PhD. Sometimes less, sometimes more. Three to four years puts us in a meaningful ballpark.

People worry about “long” vivas. Mine was four hours. I’ve heard of the occasional six-hour viva. It can seem like a long time to be on and discuss your research. But you get to those hours of discussion after years of work. You’re in a good place.

Four Hours

My viva was four hours long. It was over in an eye-blink. I left my viva thinking, “What just happened?” I was tired because I had slept badly, and the viva was quite an involved discussion at times. Still, I was really surprised to find out four hours had gone by. I’ve heard similar stories from other PhD graduates: vivas that seemed to take no time at all despite clocks and watches clearly showing hours have passed.

Two/three/four hours at the end of years of research, learning and development – by comparison it really is an eye-blink. In the moment it could fly by, or there could be questions that drag on and on (I remember those too). But relative to all that you’ve done the viva is a tiny step in the PhD process: one of the final ones, but one at the end of a great deal of work by you. However long the viva is, you’re in a good place to meet the challenge.
