Give and Take

When you’re asked a question at the viva:

  • Give a response to the question;
  • Take your time to do it.

Any question. Any kind of question. Give a response, take your time.

There are no prizes for speed and only your own stress for rushing.

There might not be an answer but you can always respond with an opinion, a hunch, an idea or a question.

Give a response, take your time.

EDQs

Or Extremely Difficult Questions.

You could make some educated guesses at what these might be for your viva:

  • A question on a topic you struggle to talk about.
  • A question about the bit of your PhD you didn’t like.
  • Something which is all about an examiner’s work.
  • Something completely unexpected.

It might be a surprise in the moment or something you’ve been dreading but an EDQ isn’t the end of the world – or, worse, the end of your viva.

If you’re faced with an EDQ then:

  • Pause and think before you respond – which is good advice for a REQ* as well.
  • Remember you can ask for clarity. Ask your examiners to say more.
  • Remember to take your time. More than simply pausing, remember it’s not a race or a rush.
  • Explore your thesis to help you support what you’re saying.

Remember that every question is an opportunity for you to demonstrate something but you are not expected to know everything. EDQs don’t have to dominate how you engage with your viva or be on your mind as you prepare.

 

* Really Easy Question!

Known & Unknown Questions

It’s likely that you’re very aware of many questions you’ve been asked in the past:

  • Questions about why you’ve done the research you’ve done;
  • Questions about how you’ve done your research;
  • Questions asked because people don’t know what you know;
  • Questions asked for greater clarity from you;
  • Questions that help unpick what you’ve done;
  • Questions that show the limits or problems of your research.

And, I’m sure, a lot more besides.

It’ll help you to think about these past questions as you prepare for your viva. If any of these questions have been asked several times during your PhD it’s worth thinking about why that is. Perhaps you’ve addressed the question now in your thesis but it’s still worth thinking through. Perhaps some questions are natural consequences of what you’ve done before.

You can be aware of the many questions you’ve been asked in the past. You don’t have to have an answer for all of them though – and you don’t need to worry about the many possible unknown questions you could be asked at your viva.

Or rather, you might worry but you can do more than that.

For example, you can:

  • Read your thesis in preparation;
  • Consider your past questions and think again about how you’ve responded before;
  • Create summaries that help you to focus on what matters in your research;
  • Rehearse for the viva to give you opportunities to think and respond in the moment;
  • Make opportunities to tell others about what you’ve done;
  • Find out more to know the general expectations for viva questions.

You can’t prepare to answer every possible question at the viva by having a big list and thinking about them all – but you can be ready to respond to any possible question that comes up even if it is an unknown.

“No”

It might be the start of your response to a particular question at the viva.

It’s unlikely to be the only thing you can say or the only thing you need to say in response to that question.

 

(see also: “I don’t know”, “My supervisor told me to” and “I’ve not thought about that before”)

Second Thoughts

They’re probably better than your first thoughts at the viva.

First thoughts might come from nerves, worry, mishearing a word, wanting to get a point across or wanting to move past a question as quickly as possible.

Second thoughts are definitely considered. They might be the same as first thoughts but they might have more nuance or be better expressed. They’ll slow the pace a little and show your thinking.

Think, then think again. Take your time to give the best responses you can at your viva.

On Opinions

There’s a good chance, whatever your research area, that you can be asked a question at your viva for which you have no answer. There’s a chance even that you could be asked a question for which no-one has an answer – there are simply opinions.

When you have an opinion – or are called to think and explore your opinion in the moment – it helps to pause and think a little. There’s plenty of time to do that in your viva.

  • You can check something in your thesis if you need to.
  • You can make a note or write down a few thoughts.
  • You can ask for information.

None of this is evading the question: it’s all geared towards you offering the most considered opinion you can depending on the situation.

In fact, to engage well at the viva, whatever the question, pause and think before you respond. Even if you have an answer ready, something you’ve considered and refined for years. Pause and think just in case there is a subtlety in the question that you’re rushing past in your desire to show what you know.

When you’re called on for your opinion at the viva give yourself a little time to respond well.

Maybe

It always helps to pause when you’re asked a question at your viva; take some time to think, consider, get your thoughts in order (and make notes, check your thesis and so on) before you respond.

You could do all of that and still, in that moment, think, “Well, maybe…” Taking everything into account, you might not know something or might not be sure.

That’s OK. The viva is not about demonstrating perfection or total knowledge: it’s about showing what you did, why you did it and how you can do things well. If you listen carefully, think carefully and your careful response to one particular questions begins with “Maybe…” then you’re doing fine.

You don’t need to know everything. You don’t need to have thought of everything beforehand.

Listening

It’s a big part of the viva.

There are no gotcha questions and hazing remarks. Your examiners are there to listen and they’ve giving you opportunities to speak about your work, your PhD journey and yourself.

They’re there to listen but you have to listen first. The questions they ask and the discussion they prompt are your opportunities to do well. You have to listen carefully to make the most of them.

When they ask a question, pause and check that you understood it. Ask for clarification if you didn’t. Consider what it all means and take your time to respond well.

They’ll be listening.

“I Had To”

Those three words might be true but they will never be enough for a response to a question in your viva.

There’s always a reason and it’s always worth digging into. You always need the “because” or the “why” behind doing things a certain way in your PhD.

 

“I had to” might be the first words that come to mind with something difficult or even something particularly challenging in your research journey. If you know of situations like this ahead of your viva then it will be helpful to consider what else you could say. If it’s a sensitive topic you’ll probably still need to say something more than “I had to” – so think in advance what you might feel comfortable saying.

Moments & Pauses

Your viva is a conversation.

It will have a rhythm and a flow.

The direction is lead to some extent by your examiners with their questions and comments, but you set the pace with your responses.

Pause to think, to breathe, to check and to be sure.

Take a moment to break up what you’re saying.

The viva is a conversation and you want it to flow well – but the viva is an important conversation that needs time. You need time to think well and respond well.

A moment here or there will not increase your viva length dramatically or negatively. Taking a pause to respond well can only help your viva and your performance.
