Surgery (MRCS Part B OSCE)
Walk into your MRCS B OSCE having already done it — dozens of times
Practise the real MRCS B stations out loud against a simulated patient who responds realistically, any time of day. Get instant, examiner-style feedback after every encounter — no study partner, no booking, no waiting.
What is the MRCS B OSCE, and how do you practise for it?
The MRCS B OSCE is a spoken clinical exam that assesses how you take histories, explain information, and handle patients and colleagues under timed conditions. The most effective way to prepare is to rehearse the real stations out loud — with MedMock you practise them against a realistic AI patient any time of day and get instant, examiner-style feedback after every one.

⏳ Count down to the next MRCS B sittingYou can know the medicine and still freeze in the room
The MRCS B tests more than what you know — it tests what you can do with a real person in front of you, under time pressure. You can read every guideline and still mishandle the opening line, miss the patient's cue, or run out of time.
There is only one way to address this: practise out loud, repeatedly. The difficulty is finding someone to practise with. Study partners cancel, seniors are busy, and courses cost hundreds of pounds and book out months ahead — so most candidates arrive under-rehearsed and rely on adrenaline on the day.
MRCS B OSCE practice, on demand
The Intercollegiate MRCS Part B OSCE, set at the level of a trainee early in the second year of core surgical training and required for entry to ST3. The real exam has 17 examined stations of 9 minutes, each with 1 minute to read the instructions: 8 Applied Knowledge stations (anatomy, surgical pathology, applied surgical science and critical care) and 9 Applied Skills stations (history taking, giving information, and clinical and procedural skills). Each station is marked out of 20 and you must pass both Knowledge and Skills. MedMock covers the spoken stations: the anatomy and pathology viva, the applied science and critical care viva, history taking, and giving information to a patient, a relative or another health professional. The hands-on clinical and procedural skills stations are not simulated.
MedMock gives you a simulated patient who responds realistically, available 24/7. Pick a station, have a genuine spoken conversation, and get instant, examiner-style feedback the moment you finish — scored against what genuinely matters in the MRCS B. No rota conflicts, no study partner, no waiting your turn. Simply practise whenever you have a few minutes.
How it works
Choose a station
Pick from the MRCS B stations — all 6 that MedMock runs, or let MedMock surprise you the way exam day will.
Have the conversation
Speak naturally, out loud. The AI patient or examiner responds in real time — with follow-up questions, emotions, cues and unexpected turns, just like the real stations.
Get instant feedback
The moment you finish, you get specific, examiner-style feedback and a score — what you did well, what cost you marks, and precisely what to fix before the next attempt.
Why candidates practise with MedMock
Practise out loud, any time
No study partner, no booking, no rota clash. Open MedMock at 6am or midnight and run a full station in minutes.
All 6 stations, endless variations
You will never simply memorise answers. Each run is different, so you build the real skill — adapting in the moment.
Examiner-level feedback in seconds
Know exactly where you lost marks and how to address it, instead of guessing why a mock session went poorly.
Turn nerves into muscle memory
By the time you sit the MRCS B, the format feels familiar — because you have already done it dozens of times.
A fraction of the cost of courses
Avoid the hundreds of pounds you would spend on a one-off exam course, and practise a deep bank of scenarios instead.
Practise anywhere, from your phone
On a break, during the commute, between lessons or shifts — your preparation goes wherever you do.
Practise every station
MedMock covers the stations you will face in the MRCS B OSCE. Rehearse each one until it feels routine.
Anatomy & Surgical Pathology Viva
Examiner-led viva on the surgical anatomy of a named region, or on surgical pathology. 9 minutes, with 1 minute to read the instructions.
Applied Surgical Science & Critical Care Viva
Examiner-led viva on the applied science and critical care of a surgical patient, which may include interpreting results you are shown. 9 minutes, with 1 minute to read the instructions.
History Taking (Surgical Presentation)
Take a focused history from a patient. After up to 6 minutes the examiner stops you, asks you to summarise your findings and asks you some questions. 9 minutes, with 1 minute to read the instructions.
Information Giving & Consent
Give information to a patient about a diagnosis or an operation, including consent. 9 minutes, with 1 minute to read the instructions.
Breaking Bad News / Difficult Conversation
Give difficult information to a patient or a relative. 9 minutes, with 1 minute to read the instructions.
Giving Information to a Health Professional
Refer or hand over a surgical patient to a colleague, in person or by telephone. 9 minutes, with 1 minute to read the instructions.
Example scenarios
A sample of the scenarios you will practise — each plays out as a live, spoken conversation, not a script to read.
“I would like to ask you about the femoral triangle. What are its boundaries and contents, and what lies immediately medial to the femoral vein?”
“A 68-year-old is 24 hours after an emergency laparotomy. He is passing little urine. Here is his arterial blood gas. Talk me through it.”
“A 34-year-old woman is listed for a laparoscopic cholecystectomy for symptomatic gallstones. Explain the operation to her and take her consent.”
“You are the surgical core trainee on call. Telephone the vascular registrar to refer a 71-year-old man with a cold, painful right leg.”
MRCS B practice — your questions answered
How realistic is MedMock's MRCS B practice?
Every scenario is built around the real MRCS B OSCE format and the domains examiners assess. You speak out loud and the AI patient responds in real time, so it feels far closer to the day than reading notes or rehearsing silently.
How does the feedback work?
As soon as you finish a station, MedMock gives you instant, examiner-style feedback and a score — highlighting what you did well, what cost you marks, and exactly what to work on next.
Can I practise specific MRCS B stations?
Yes. You can pick any of the 6 stations to drill a weak area, or run a mixed set to simulate the real exam.
Do I need a study partner or a fixed time slot?
No. That is the point — MedMock is available 24/7 and you practise alone, out loud, whenever it suits you. No coordinating diaries, no waiting for a course date.
Is MedMock right for me if I am sitting the MRCS B?
If your MRCS B exam involves speaking — histories, explanations, breaking news, dealing with patients and colleagues — then spoken rehearsal is exactly what MedMock is built for.
How much does it cost?
Far less than a one-off exam course. Every plan includes a monthly credit allowance, and everyone starts with a free trial — no card required — so you can see how it works before paying. See current options on our pricing page.

While Medmock checks each format against the latest published guidance from the responsible body (the Royal Colleges, the Federation of Royal Colleges of Physicians, NHS England, the GMC and others), always consult your official candidate guidance or applicant handbook for the definitive, up-to-date station requirements for your specific cohort.
