Knowing Your Stuff

At the viva you’re expected to know your stuff, whatever that might mean for someone in your field or discipline. Broadly speaking: you’re clever, you’ve done the work and you’re assumed to be capable.

It’s not hard to worry that you might be missing something, but keep in mind, to set the right perspective:

  • Knowing your stuff doesn’t mean you need to know everything.
  • Knowing your stuff doesn’t mean you are expected to have a fast recall of every detail.
  • Knowing your stuff doesn’t mean having read every paper.
  • Knowing your stuff doesn’t mean guessing every question your examiners might have.
  • Knowing your stuff doesn’t mean knowing all of your examiners’ stuff too.
  • Knowing your stuff doesn’t mean figuring things out quickly.

At the viva, knowing your stuff means being knowledgeable, capable and being willing to engage with your examiners’ questions and the discussion that follows from them.

To get as far as you have you must know your stuff: it’s the only way anyone could get to submission.

The Build-up

At submission sketch out a viva prep plan.

You might not know your viva date but that’s OK: you know your current situation. You know how busy you are and you know what responsibilities you have. With a little reflection you can also get a good feeling about how you need to approach getting ready.

A sketch of a plan can take account of busy-ness and obligations. Do you need two weeks to get ready or is it safer for your stress and your time to have a month? Sketch how you would do the work.

Start small and build. Day one of viva prep doesn’t have to mean reading your whole thesis, checking ten papers and having a mock viva. Build up to that. Read a little and then do more the next day.

The last week of viva prep will probably be busier than the first – but the last day might be more relaxed as you realise you’ve built up everything you need for meeting your examiners.

After all, you’re building on solid foundations.

Imperfect Metrics

Viva success is not based on how many days you showed up to do your work.

Success isn’t determined by the number of chapters you have written, the number of papers you cited, how many conference talks you’ve delivered or whether you have several publications out there.

All these numbers can give a boost to your confidence though. The numbers mean you did something, repeatedly, and over a long period of time.

You need to look a little deeper for proof of your knowledge and capability as a PhD candidate, but a good starting point might be the imperfect metrics of a few numbers that show you did the work.

They count for something.

The Biggest What If

What if it happened at my viva?

Whatever it is, there would be consequences. That’s a simplified way to look at the situation, but it’s the most accurate. The most dire “what if” differs for everyone; depending on the exact details the consequences could vary a lot.

It might be forgetting something. In which case you could take time to recall. You could annotate your thesis to help you remember. There’s something to do.

It might be worrying about saying “I don’t know” – which is a common viva worry. Saying “I don’t know” is not the end of the viva. Rehearsal before the viva helps a lot. Remembering you can pause in the viva to think about why you don’t know.

It might be anxiety about failing. Failure at the viva is rare. This might be the biggest what if: which means that if you worry about it then you have to do something to move on.

If you’re really worried that you might fail then you need to explore why. You need to talk to your supervisors or someone you trust. You need to figure out what’s at the root of the worry. You need to do something.

It doesn’t just happen. You don’t just think about it for no reason. If you can figure out what’s causing you to wonder “what if…?” you can then take steps to move past it.

Contributions Matter

“How would you define your significant, original contribution?”

That’s a hard question for a lot of reasons.

It asks for specifics, your opinion and makes an assumption that there is one big thing you’ve done through your research. Personally, I would struggle to respond because I didn’t have a single focus during my PhD: my thesis was a collection of results, not one overall idea that I explored.

It’s a hard question, but it could be rewarding to unpick nonetheless. Reflecting might reveal some helpful ways to share your research with your examiners (and others).

It’s also helpful to reflect on all of your contributions, big and small. Look back over your PhD and think about your results, achievements and victories. What do they all amount to? Whether or not there is a single headline conclusion to point to, what do your contributions mean?

Remember that contributions can be a stepping stone to confidence: recognising what you’ve achieved can be a helpful way to boost how you feel.

Normal vs Typical Vivas

The normal viva doesn’t exist. It’s a myth. There’s far too much variety in research, individuals and circumstances to allow for a normal viva.

There are typical vivas. There are patterns, trends, regulations and processes that produce reliable expectations.

For example, vivas typically last several hours, conclude with a short intermission while the (typically) two examiners confer and most often result in success – with candidates being asked most often of all to complete minor corrections.

There is a tension between the seemingly opposite ideas that vivas are unique and vivas follow patterns.

Explore the patterns to prepare for your unique experience.

“Have A Great Time”

…is a sentiment that is a bit like “Good luck” or “Don’t worry” when related to the viva. It’s very well meant, but there might not be a lot that you can do directly.

While you can’t control whether or not you will have a great viva, you can influence things. You can:

  • Do the work
  • Plan and prepare.
  • Check the regulations.
  • Reflect on your PhD journey to build your confidence.
  • Check out your examiners.
  • Read, review and rehearse.

Having a great time at the viva does not rest on good luck. It won’t happen if you simply don’t worry. As with all of your PhD success, you have to do the work.

Final Preparations

My last viva prep task was to knock on my supervisor’s door with fifteen minutes to go, “Hi Hugh, just to check one more time, a genus 2 mutant can be defined as….?”

What will your final prep be?

Perhaps you’ll just check you have everything in your bag. Maybe you’ll focus on re-reading something one more time. Your last prep step could be to relax with a cup of coffee.

Or like me, your last task will be to stress at the last moment.

 

There’s an element of choice involved. You can plan your viva preparation. Sketch out a plan when you reach submission. You don’t need to account for every minute of every day until your viva, but by looking ahead you can remove stress, rush and a lot of doubts.

The last step in getting ready for your viva could be tiny or could be a big task. It’s better if it’s not panicked or stressed.

The Greatest Hits

What are the best and most valuable references in your bibliography?

What were the biggest achievements of your years working on your research?

What could make the biggest impact now that your thesis is complete?

 

If you reflect on where your work comes from, what you did and where it could go then you have considered the context for your contribution, the contribution and a possible future for it. That’s a good piece of reflection as part of viva prep!

Use The Right Tools

We use tools to help ourselves.

Screwdrivers come in all sorts of shapes and sizes. Saws vary depending on their purpose and the materials they’re designed to cut. Hammers can be used to assemble or destroy.

Tools are useful to make or maintain, to remedy small problems or big situations.

 

So what tools are you taking to your viva?

Perhaps you have something physical to show your examiners, but more likely you’ll be demonstrating intellectual tools that you have constructed over the course of your PhD.

You’ll show your knowledge. You’ll share your understanding. You’ll demonstrate your capacity for thinking like a researcher in your field.

These are the tools you need to do well. They’ve helped you make the research in your thesis and can now help you to make good on that promise at your viva.

Don’t forget that tools need maintaining too – viva prep is essential for sharpening yourself!
