Study partner, revision course or AI examiner: how to practise for a viva or OSCE
There are three ways to rehearse a spoken medical exam: with a study partner, on a revision course, or against an AI examiner. A partner is free and the closest thing to a real person, but only as good and as available as the partner. A course gives you real examiners and real patients, but for a day or two and typically at a cost of hundreds of pounds. An AI examiner is available whenever you are and marks every answer, but cannot examine a real patient with you. Most candidates do best combining them: daily spoken repetition on their own, a partner for realism, and a course close to the exam.
What actually gets marks in a spoken exam
Written exams test what you know. Vivas and OSCEs test whether you can retrieve it, structure it and say it clearly under pressure, to someone who interrupts. That is a performance skill, and like any performance skill it improves with spoken repetition and feedback — not with more reading. Whichever method you choose, the test of it is simple: how many times a week does it get you answering out loud, and does anyone tell you what you missed?
A study partner
Good at realism: a person can interrupt you, look unimpressed, and push on the point you hoped to skate over. It costs nothing, and teaching each other is itself good revision. Weak at availability and calibration: rotas rarely line up, sessions get cancelled, and a partner sitting the same exam has the same blind spots as you — they cannot mark you against a standard neither of you has seen. Partners also tend to be kind. Best for one or two sessions a week, for realism and morale.
A revision course
Good at authority: real examiners, often real patients with real signs, a realistic circuit and an honest view of where you stand against the pass standard. For exams with physical examination, nothing else puts your hands on a patient. Weak at volume and timing: a course is a day or two, you may get only a handful of turns in the hot seat shared with the rest of the group, and what the examiner told you fades within weeks if you have no way of rehearsing it. Courses typically cost hundreds of pounds, plus travel and leave. Best as a benchmark four to eight weeks out, while there is still time to act on what you are told.
An AI examiner
This is what MedMock is. Good at volume, availability and consistency: it is there at 6am and after a night shift, it never cancels, it will run the same station ten times without getting bored, and it marks every answer against the exam's own domains and shows you the answer you did not give. Nobody watches you get it wrong, which matters more than people admit. Weak at anything physical: it cannot put a patient in front of you, watch your hands during an examination, or tell you that you looked at the floor. It is a simulation — the patients and cases are fictional, and it is a revision tool, not clinical guidance. Best for the daily repetition the other two cannot give you.
How most candidates combine them
Three months out: build knowledge, and start answering out loud early, even badly. Two months out: short daily spoken sessions on your own, plus a partner once or twice a week. Four to eight weeks out: a course, for a benchmark and for the physical stations. Final fortnight: timed full circuits, and the stations you have been avoiding.
What this costs
A partner is free. A course is typically hundreds of pounds for one or two days. MedMock starts with a free trial of 30 credits — about half an hour of talking, with no card required — and subscriptions start from £20 a month for student exams, rising with the seniority of the exam. One credit is roughly one minute of spoken practice.
Frequently asked questions
Can I pass a viva without a study partner?
Yes. What a partner provides is spoken repetition and someone to notice what you missed, and both can be had other ways. What you cannot do without is saying your answers out loud: reading and thinking through an answer feels like practice and is not.
Is a revision course worth the money?
For most candidates, one is — mainly for the benchmark against real examiners and, in exams with physical examination, for real patients. It is poor value as your only spoken practice, because a day or two cannot give you the repetition a performance skill needs.
Is practising with an AI examiner realistic enough?
For the spoken part — structuring an answer, being interrupted, thinking aloud under time pressure — it is close, and it is available every day. For physical examination and procedural skills it is no substitute for a patient.
How often should I practise out loud?
Short and daily beats long and weekly. Twenty minutes a day for six weeks is more spoken practice than most candidates get in their entire preparation.
