It’s finally here – the notorious viva. As you begin to prepare, it may seem like the most important hurdle of your academic career thus far. But let’s take a moment to acknowledge that reaching this stage of your PhD is a huge achievement in itself. You’ve put in the work, and now you have the opportunity to discuss it with two experts in your field. It’s a chance to showcase everything you’ve done and how far you’ve come.

The viva isn’t just about defending your thesis – it’s a way for examiners to confirm that you wrote it and that your research makes an original contribution to the field. They want to see that your work has value: novelty, a strong hypothesis, and results to support it. It’s normal to feel daunted, but like any exam, the right preparation can turn the viva into a rewarding and even enjoyable experience.

Every university has slightly different guidelines, so check your institution’s website to make sure you understand the process. Will it involve a presentation followed by questions, or is it purely a Q&A session? Where will it take place? What can you bring with you? It’s also worth familiarizing yourself with the possible outcomes – not to stress yourself out, but to be fully prepared. We’re confident you’ll do great, and with the help of this guide, you’ll walk into your viva feeling ready.

A note on mindset

As you start preparing, take a moment to check in with yourself and consider your mindset. This exam is just a small part of the years of work you’ve already put in – you know your research better than anyone else in the room. Your examiners will be genuinely interested in what you have to say (and let’s be honest, how often does that happen?). Most importantly, your supervisors believe you’re ready, and they wouldn’t have let you get to this stage if they didn’t have confidence in you. Trust that you’ve earned your place here.

Preparation strategies

Familiarize yourself with your work

Know your thesis inside out: methodology, results, conclusions, and broad concepts. If it’s been a while since you last read certain sections, take time to refresh your memory. Be clear on the key decisions you made and be prepared to justify them.

Revisiting broad concepts, especially those introduced in your introduction, will also be invaluable. You don’t need to recall every detail, but having a concise explanation for each concept will help you avoid stumbling over your words early in the exam.

Top tip: As you read through your thesis, jot down any edits you want to make – typos, grammar tweaks, or reference updates. Remember, it’s still a draft, so tracking these now will make it easier to incorporate examiner feedback later.

Know your examiners

Take the time to research both of your examiners – their work, their research interests, and any papers they’ve published that relate to your own. Pay particular attention to any papers you’ve cited in your thesis, as they’ll likely ask you to justify why you referenced them and how their work connects to yours.

Keep in mind that while you know your research better than they do, the reverse is also true – they know their own work inside out. They’ll likely draw connections between their research and yours, so having an understanding of their methods and perspectives will help you anticipate their questions and engage in a more confident discussion.

Research the field

Take some time to brush up on recent publications, major news, and ongoing discussions in your field. Use resources like PubMed, forums, and research summaries to stay informed, but don’t feel pressured to absorb every detail.

You may be asked to contextualize your research within the current landscape, so having a broad understanding of recent developments will be invaluable. A general awareness of key trends and debates will help you engage confidently in discussion without overwhelming yourself with unnecessary detail.

Practice, practice, practice!

Do at least one mock viva with your supervisors or colleagues, making sure you’re critically engaging with your own work. Read your thesis as a reviewer would—what questions might they ask? Where are the weak spots? Be ready to challenge your own research.

Approach the viva with a reflective, not defensive, mindset. Acknowledge limitations and explain what you would do differently if given the chance. As you review your thesis, jot down notes in the margins – why you made certain research choices, why you referenced specific studies, and how your work connects to broader questions in your field.

On-the-day logistics

You’ve put in the preparation – now set yourself up for the best possible experience. Give yourself plenty of time in the morning to get ready without rushing. Double-check the venue, plan your journey, and aim to arrive early so you’re not stressing about travel delays. Have everything you need ready in advance, whether it’s printouts, digital copies, notes, or even water, so you’re not scrambling at the last minute.

You’ve got this

The viva may feel like a huge moment, but remember, it’s just the final hurdle in a journey you’ve already conquered. You’ve done the research, written the thesis, and put in the effort to get here. Now, it’s about having a conversation with people who have a genuine interest in your work and an understanding of the field.

Look after yourself in the lead-up – don’t run yourself into the ground with last-minute cramming. Stay balanced, take breaks, and trust in what you already know. And most importantly, try to enjoy it: this is a rare chance to share your research from start to finish. You’ve got this!
