More Things I Don’t Know

Two years ago I shared this little post about things I didn’t know about the viva. Two years on and I have thoughts about some of these!

  • What percentage of candidates fail their viva? Around 0.1% is my estimate, based on lots of conversations with doctoral college staff.
  • How well does a viva over Skype work compared to an in-person viva? What’s Skype…? Online vivas seem to work well, all things considered, and like anything just require a little adjusting to.

I’m still wondering about thesis-by-publication differences, and the vivas of full-time and part-time researchers.

I also realise that I don’t know for sure how common a presentation is at the start of the viva (they seem to be quite rare). It’s unclear whether or not the switch to Zoom vivas is going to be remain common in the long term. I don’t know if there is a universal viva prep help idea that can make a difference for every candidate (though I keep working on it!).

I’ve accepted that there will always be things I don’t know about the viva. Some I can find out, some I can explore and make sense of, and some things might always remain unknown. I can keep exploring a little but I also have to focus on what I do know, what I can share and how I can help.

Consider your research. There are things you don’t know. You can explore that a little, to be sure of what you don’t know and why – but keep your focus squarely on what you do know, how you can be certain, and how you can best share it with others.

There’s always more. But by now you must know enough.

More More More

I don’t remember a lot of the day-to-day life of my pure maths PhD now. I remember little sparks, breakthroughs, and the feeling of being “in the zone” while trying to figure something out.

I also remember, as my PhD went on, the growing feeling that there was always more I could do.

There were more ways to apply the ideas I had developed.

There were more papers to read to find more methods for exploring my field.

There were more questions to ask, and more answers to be found – more to explore.

Even though of course there was a limit to how much I could accomplish throughout my PhD, there would always be more things I could do. And in preparation for my viva, while I invested a lot of time, I could have done even more. I could have spent thirty minutes more each day, an extra day of reading papers or an afternoon checking over the details of a chapter.

I think this generalises further: even with time pressures, life pressures and so on, candidates have to recognise that there will be more things they could explore or do than they have done; however much time they spend getting ready there will be more that they could do which would help them.

And we all have to take a deep breath at some point and say “No. This is enough.” You have to find a way to do that for your research and your thesis. For your viva prep, making a list in advance of what needs to be done could be helpful. Break down what will be enough for getting ready, then work towards it.

There is always going to be more, and there also has to be enough.

How Much Is Enough?

It’s a good question to ask about a thesis or a PhD, but a hard one to answer. There are lots of possible factors.

  • How much does your supervisor think you need to do?
  • How much time can you spend?
  • How many chapters or words are people telling you that need to write?
  • How many experiments/interviews/papers/tests/models/observations/questions are you being told that you need to complete?

At the start of a PhD you might struggle to respond to the question of how much is enough. All of these factors, and lots more, could make it tricky to consider.

Nearer the end you can give a response and reasons: “This much, and here’s why.”

And the sooner you decide how much is enough, the sooner you’ll be able to work towards that goal.

What’s On Your Mind?

Probably a lot.

101 questions, about life, the state of the world, what you’ll be doing in six months, what you’ll be doing next year…

What’s for dinner, what will happen in that show I like, should I call so-and-so, what am I forgetting…

And then you think about your viva.

Now 1001 questions.

What will happen? What will they ask? What do I do? What can I say? What do I say if they ask about that question or topic or thing I don’t like? What should I do? What could I do? Will they like it? When will I know?

And at the root of it all: Am I ready? Am I good enough?

Don’t drown in questions. Get them out. Write them down. Tell someone. Ask someone to help. Ask someone for information or advice.

But at the root of it all: Are you ready? You can be. Are you good enough? You will be.

Slow & Steady

Don’t rush preparing for your viva.

You’re busy, of course. You’re stressed, at least a little, most probably.

You only have so much time and you want to make sure you’re ready.

Start sooner rather than later. Do what you can. A little each day will help.

A little reading. A little writing. A little thinking. A little talking. A little practice each day.

It all adds up.

For viva prep, slow and steady helps you be ready.

One More

Before submission, you could always…

  • …read one more paper.
  • …do one more test.
  • …ask one more question.
  • …check one more thing
  • …have one more meeting.

It won’t take much to prepare for the viva, but however much you do, you could always…

  • …read your thesis one more time.
  • …check one more paper by your external.
  • …have one more conversation with a friend.
  • …write one more summary.
  • …worry one more time about what you might be asked.

There’s always more you could do, at every stage of the PhD. You don’t necessarily need to do that though. Instead, think about where you are, and think about what enough means for that stage.

The viva is one more day you get to show up and show what you can do before you’re finished.

Make the most of it.

What You Can Do

You can write a good thesis.

You can make yourself prepared for your viva.

You can know what to expect from your examiners.

You can know what to expect from the viva.

You can learn about remote vivas, if that’s likely to be the scenario for your viva.

You can build your confidence to balance out your worries.

You can’t be perfect, but you can do your best.

You can be good enough for your viva.

Are You Ready?

There’s always a thought that you could do more.

  • One more experiment before you write up.
  • One more section before the chapter is done.
  • One more paper to check or question to answer before your viva.

Before you ask yourself if you’re ready, maybe ask if you’ve done enough.

Before you ask yourself if you’ve done enough, maybe define what enough would be.

Enough research, enough of a thesis, enough prep for the viva.

Decide on enough, so you can confidently answer “am I ready?” when the time comes.

Everything? or Enough?

Have you done everything you could for your research and thesis? It’s almost impossible!

Have you done enough for your research and thesis? Probably, since most candidates do!

It helps to define “enough” before you try to decide if you’ve achieved it.

Similarly, you can’t do everything in preparation for your viva, but you can do enough. Figure out where you have gaps, where you need support, where others can help you, then work your way to being ready. Decide in advance on what you need to do before you get to work.

You can’t do everything, you can do enough.

When Do You Stop?

I remember knocking on my supervisor’s office door thirty minutes before my viva to check a mathematical definition.

I know of people who took the day off before their viva and just relaxed.

Some candidates will be checking notes almost until they go into the viva room.

It helps, as with writing the thesis, to decide in advance what you are going to do. Make a decision about what “enough” preparation looks like. What are the tasks you will complete? What needs to get done? I would suggest allowing for a little relaxation time the day before to relax your mind; perhaps you can make a special plan to do something nice, if your schedule allows?

You can stop when you’re done, and you get to decide when that is. Make that decision. Otherwise you may just keep nervously doing more and more until you start the viva.
