Average and Typical

What is an average viva?

I get this question at least once a month. I struggle to answer.

I can’t talk about length, because while there is a skewing towards two hours across disciplines, the range is pretty big. It’s tricky to talk about the exact style of the exam; it is a semi-structured discussion but the nature of questions is going to vary a lot from discipline to discipline.

Examiners will be qualified and prepared, but they might not be experts – depending on your field there might not be an expert who can examine you. I suppose it is fair to say most people find out the result within thirty minutes of the end of the viva (after a short break). Most people are fairly happy with the corrections they’re asked to do.

But what is average?

Can we change the question? How about: what is typical for the viva?

Typically it comes at the end of a successful project. Typically the candidate has spent a significant period of time becoming experienced. Typically they’ve written a good thesis. Typically they’ve continued to build on all of this work in the period leading up to the viva by getting prepared.

There are lots of ways the variety of vivas struggle to come to some average. But typically? Typically, you’re up to the challenge.

Story Time

My sister got me some Story Cubes for my birthday last month. I’d played with some before, but never had a set to call my own. They’re great for playing little story-making games and just generally for helping ideas along.

Last week as I was having a little fun they fell into the following sequence:

My mind jumped to the viva straight away!

PhD candidates spend a long time learning enough to write their thesis. Things are going well, through good times and bad, then they look ahead and all they see is questions coming their way! Questions in the viva, questions about the viva, questions and questions and questions… But help is at hand. There’s lots of support. The end is a happy one.

People look for patterns. We all carry mindsets of what we know or believe to be true. We tell a story based on what we’ve seen before. Even if you have some doubts about the viva, about the process, about how best to prepare – think about what you know from your research. Think about how you got to this point.

Think about your story.

Postscript: I kept playing with the Story Cubes, and this was the next arrangement that came up…

I’m glad this doesn’t tell a viva story!

Terms & Conditions Apply

A pass in the viva is not typically no strings attached. Most candidates have to complete some kind of corrections. These can mean different requirements at different institutions.

You can’t know what corrections you might get in advance, but you can find out what conditions they’ll have to be done under. How long is given to complete them? Who do you have to get approval from? When corrections are complete, how long do you have in order to get your final, complete thesis submitted? How long from then until you’ll have graduated?

Harsh

What could you do if an examiner was harsh?

Nevermind that they’re supposed to be fair, professional and so on. What if they weren’t? It’s easy to say don’t worry, they’re not supposed to be, but what could you do if you felt they weren’t fair?

  • …I don’t believe you!
  • …I don’t agree!
  • …What about my work?
  • …But don’t you think that such-and-such has a more important idea than this?

What could you do?

Listen. Breathe. Take a step back. Think. Ask yourself why. Ask them why. Remember that the viva is not a Q&A. Remember who the expert in the room is. If they’re harsh, push their tone to one side and respond to their ideas or questions.

It’s extremely unlikely that an examiner would be harsh, but it’s possible that they may have an opinion – fair, balanced and appropriate – that still catches you off guard. A question that throws you. Pausing, listening just to the question and not the tone, setting your feelings aside for a second – all of this can still help.

Event Horizon

At a workshop in December, a PhD candidate told me he couldn’t see past the “event horizon of his viva.” This put into words, quite beautifully, something I’ve felt for a long time about the important events in my life. Some things seem so massive that they draw you in completely. There’s no escape from thinking about them.

Time and space breaks down at the viva. Perspective gets skewed. The viva feels so big it distorts everything. What can you do as it draws you in?

  • Look back: you’re getting close, but you’ve come a long way to get to these few hours (and must have done a lot to get there)
  • Look forward: make plans for afterwards. Focus on the post-viva reality. This isn’t the end.
  • Look around: there are people who can help you in all sorts of ways, even if that’s just to help you get a bit of perspective.

Steer your focus. The viva doesn’t have to be a black hole.

Defending or Defensive?

In the viva you may have to defend your work. Ideally, you need to do so without becoming defensive.

Defending: “This is why I made this choice…”

Defensive: “I made the right choice!”

Defending: “…that’s a fair question. I think…”

Defensive: “…that’s not relevant because…”

Defending: “…well, I think I addressed this point in Chapter 3…”

Defensive: “…oh yeah? Well what would you know!”

Stay on the right side of defending in the viva. No thesis or PhD is perfect. You can defend, explain and explore your decisions and conclusions, of course, but don’t make it personal. Make your examiners’ comments about the work.

Take a step back and breathe if you feel that you’re being criticised. If your examiners don’t agree, ask them why. Listen and then bring it back to what you did and why. That’s what will help your answers.

Variables

There are lots of things people think will have an impact on their viva or their prep. Here’s a partial list of factors people think could make a difference, for good or bad:

Your examiners. Your institution. The number or types of awards or results. Whether you were part-time or full-time. Home or international. Number of supervisors. Time spent on your PhD. Do you have a Masters? How long between submission and the viva? Will you have an independent chair? Have you cited your examiners? Number of references in your bibliography. Number of chapters in your thesis. Number of published papers during your PhD. Number of hours spent on prep. Will you have had a mock viva? Have you read a book about the viva? Did you go to a workshop about the viva?

I’m a mathematician and there’s part of me which would love to take all of these variables and make an equation. But there’s far too many. Lots of them could make a difference.

So why not focus instead on the constants? The things that are always there.

You did the work. You made the choices. You steered yourself. Your examiners are capable researchers, who know what they’re doing in the viva. You are a capable researcher by the time you submit, and have the time to prepare yourself for the viva.

Focus on the constants that hold true for everyone.

Breezy

The wind blows. That’s what it does. Some days it’s fast, some days it’s a gentle breeze, and some nights it sounds like it is bringing the end of the world. Depending on the situation I might wear a coat, bunker down, pick up the bins in our garden, or just go for a stroll and try to smile as my hat flies off.

Experiences shape perceptions and responses.

Back to the blog about viva help!

The viva is questions. Questions about your work. And you’ve been asked questions before. Maybe not this or that, but you’ve been asked questions. And you’ve answered them. You know how to deal with difficult questions about your research. You know how to explain your work. You know how to think around your research area.

You can worry about a unique or novel situation, but you can also still prepare for it. You did the work, you wrote your thesis, you can succeed in the viva.

The 99th Percentile

“Excuse me, can you reach that?” Usually, yes. I’m six feet and four inches tall and in the 99th percentile for height in the UK. I didn’t have to work on it much, it just happened.

PhDs don’t just happen. Nobody gets onto a PhD programme, or gets through one, by being lazy or unskilled. You have to know things and you have to do things. Yet you compare yourself to others and you grow to doubt yourself. The viva comes around and you wonder, “What will the examiners think? What will they ask? How will they rate me?”

There’s a background fear in some candidates that examiners are just better. And not in a small way. “Examiners are at the 99th percentile!”

They’re six feet four, looking down on you.

Right?

I’m not so sure. It matters what you measure. Does it matter, assuming that it’s true, that your examiners are at the 99th percentile? Are you being examined on your total knowledge of your field? And if you were, wouldn’t you comfortably be in the top 90% or higher?

And what percentile are you at when it comes to more than your field? Where are you when it comes to you niche? When it comes to your research? Your thesis?

Your examiners may know a lot, and they may have experiences and knowledge that you don’t – but they don’t have YOUR knowledge and YOUR experience, or YOUR considered perspective from years of study.
