The Best Way to Practice for a Viva Exam

For UK and international postgraduate trainees, the best way to practice for a viva exam is mock viva rehearsal with feedback, focused drills, and a tight debrief loop.

  • Mock viva practice
  • Viva Technique
  • Exam psychology
  • Deliberate practice
  • Oral exam preparation

The best way to practice for a viva exam is to spend most of your prep time answering aloud under mild pressure, then fixing one weakness at a time. Reading helps, but it does not train pacing, structure, or recovery when you are interrupted. The candidates who improve fastest usually work in a loop: answer, get challenged, debrief, repeat.

If you want one practical rule, make at least half of your revision active. That means mock viva practice, short answer drills, and reruns of the same stem after feedback — not just notes, question banks, and highlighting.

Why this matters

Examiners are not only listening for facts. They are listening for judgement, prioritisation, structure, and whether you sound safe when the case becomes messy. In a spoken assessment, knowledge you cannot organise quickly often stays hidden.

Format-match matters. Current spoken assessments differ a lot: MRCP(UK) Part 2 Clinical Examination currently uses the PACES23 five-station carousel, the MRCGP Simulated Consultation Assessment uses twelve 12-minute consultations with three minutes of reading time, and MRCOG Part 3 uses a 14-task circuit with 12 minutes per task including reading time. Your practice should resemble the station you are actually sitting.

Official prep resources point the same way. MRCP(UK) directs candidates to demonstration videos, RCGP provides an SCA consultation toolkit and webinars, and RCOG Part 3 revision resources include circuit practice and video demonstrations. Spoken assessments are performance tasks, so performance-style practice should dominate your prep.

The best way to practice for a viva exam

Use a layered method, not one tool. Each layer trains a different part of exam performance.

  • Solo drills for speed and structure: practise the first minute of an answer, differential diagnosis summaries, explanation of risk, consent, or management plans.
  • Peer mini-mocks for repetition: short, timed stations with a colleague are the fastest way to build fluency.
  • Senior mocks for calibration: a consultant, registrar, trainer, or recent successful candidate will spot weak prioritisation and vague language quickly.
  • AI or audio-only drills for extra reps: useful when nobody is available, especially for interruption practice and trimming waffle.

If time is tight, do not cut the rerun. The second attempt after feedback is where technique usually changes.

A simple answer framework

Most weak answers ramble because they start in the middle. Give yourself a reliable order.

  • State the problem and immediate risk.
  • Say what you need next: key history, examination, observations, or test results.
  • Give your leading differential or working diagnosis.
  • Offer an initial plan, escalation, and communication points.
  • Finish with review, safety-netting, or follow-up.

For example, if you are given a 67-year-old with central chest pain, a strong opening sounds like this: high-risk chest pain until proved otherwise; my immediate priorities are ABCDE assessment, monitoring, ECG, IV access, analgesia, and early senior help if unstable. Then I would take a focused history for acute coronary syndrome, pulmonary embolism, and aortic pathology, examine for haemodynamic compromise, and start treatment according to the most likely cause while arranging urgent investigations. That opening tells the examiner you know what matters first.

How to run a mock viva that actually helps

A good mock viva is slightly uncomfortable but very specific. Aim for realism, not drama.

  • Use a real stem and strict timing.
  • Ask one clear opening question, then let the candidate speak.
  • Interrupt once or twice with a new fact, concern, or complication.
  • Mark only three domains: structure, safety, and communication.
  • Stop early if there is one major flaw that keeps recurring.
  • Rerun the same stem immediately after feedback.

What a useful debrief sounds like

Good feedback is concrete.

  • You named the emergency too late.
  • Your plan was safe, but the structure disappeared when I interrupted you.
  • You had the right diagnosis, but you did not show how you got there.
  • Your explanation to the patient was accurate, but too dense.
  • Your close was strong: you summarised, checked understanding, and safety-netted.

Bad feedback is simply be more confident. Confidence usually improves after structure does.

A useful mock should also end with one change for the next attempt, not ten. If the candidate’s first minute is disorganised, fix that first. If they sound safe but robotic, work on signposting and natural language next time.

Practise the parts, not just the whole station

Consultation-style exams make this especially obvious. RCGP guidance for the SCA highlights the opening, a clear structure, signposting, and summaries; it also says there is no preferred consultation model and warns against formulaic empathy. That is a useful rule for any spoken exam: be structured, but do not sound rehearsed.

Drill the opening minute

Take ten stems and do only the first 45 to 60 seconds of each. Your job is to identify the agenda, the risk, and the direction of travel.

In a GP-style scenario, that might mean opening with priority and purpose rather than history dumping: you have brought your 3-year-old because of wheeze and fever; before anything else I want to know how breathless they are right now, whether they are drinking, and whether there are red flags that mean same-day assessment.

Drill recovery after interruption

Ask your practice partner to drop in a new fact at minute one: actually she is 28 weeks pregnant, he refuses admission, or the blood gas shows severe acidosis. Your task is not to stay polished. Your task is to pause, reprioritise, and say what changes.

This is where many candidates become obviously safer. They stop trying to protect a memorised answer and start behaving like a clinician.

Drill the close

A lot of candidates spend nearly all their practice on the middle and then rush the finish. Rehearse your last two sentences: summary, decision, and safety-net.

In a structured discussion on reduced fetal movements, for example, close with what you think is happening, what you will do now, and what the patient should expect next. In a communication station, close by checking understanding and giving the next practical step.

Use AI and solo drills without fooling yourself

AI can be useful for extra repetitions, especially when nobody is free late in the evening. It is good for pressure practice, interruptions, and exposing filler phrases you did not realise you used.

Use it carefully:

  • ask for one stem at a time
  • answer aloud, not in writing
  • ask the tool to interrupt you after 45 to 60 seconds
  • request feedback under three headings: structure, safety, communication
  • rerun the same stem immediately
  • verify any clinical content against trusted sources before learning it

What AI cannot do reliably is replace a senior who knows your exam culture. Use it to build fluency. Use trainers, registrars, and peers to calibrate whether your answer would actually pass.

Common mistakes

  • Doing too much silent revision and not enough speaking.
  • Answering with a textbook chapter instead of a clinical position.
  • Hiding the key risk until late.
  • Giving a beautiful differential with no first-step plan.
  • Sounding scripted, especially with empathy or shared decision-making.
  • Never practising interruption or challenge.
  • Collecting feedback and not rerunning the stem.
  • Doing only full-length mocks and no short drills.

A realistic weekly practice workflow

If you work full time, a sustainable rhythm beats heroic weekend marathons.

  • Two short solo drill blocks each week, 15 to 20 minutes each.
  • One peer mini-mock of 20 to 30 minutes.
  • One senior mock every one to two weeks.
  • One AI or audio-only session for fluency.
  • One short error-review session built from the last mock.

Keep an error log with three columns: the stem, what went wrong, and what you will do differently in the first minute next time. Bring those weak areas forward into the next mock. Improvement comes from turning feedback into the next drill, not from admiring the feedback.

Summary

  • The best viva practice is active, timed, and feedback-rich.
  • Use a layered system: solo drills, peer mocks, senior calibration, and AI for extra reps.
  • Practise openings, recovery after interruption, and closes separately.
  • Rerun stems after feedback; second attempts matter most.
  • Aim to sound safe, structured, and adaptable — not theatrical.
