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 does not test what you know — it tests what you can do with a real person sitting across from 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, pitched at the day-one ST3 surgical trainee. This is MedMock's spoken circuit: the two Applied Knowledge vivas (anatomy & surgical pathology; applied surgical science & critical care) plus the communication stations (surgical history taking, information giving & consent for index operations, and breaking bad news). The manual clinical & procedural-skills stations are not simulated in this voice format.
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 ten minutes.
How it works
Choose a station
Pick from the real MRCS B stations — all 5 of them, or let MedMock surprise you the way exam day will.
Have the conversation
Speak naturally, out loud. The AI patient responds in real time — with emotions, cues and unexpected turns, just like a real encounter.
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 5 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 jobs on the ward — 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 anatomy and surgical-pathology viva. The examiner works through the exam grammar — identify the structure, describe its relations, give the clinical correlate, and state what is at risk in a given incision or approach — across upper and lower limb, thorax, abdomen, pelvis, head & neck, neuroanatomy and embryology, plus macroscopic/microscopic pathology, staging and premalignant conditions. Text viva: no cadaveric or prosection imagery is shown.
Applied Surgical Science & Critical Care Viva
Examiner-led applied-surgical-science viva on the physiology and science of the peri-operative and critically ill surgical patient: fluids and electrolytes, acid–base, shock and sepsis, transfusion and coagulation, nutrition, wound healing, microbiology and antibiotics, oxygen delivery and organ support. May be anchored to an ABG, U&E panel, ECG, chest or abdominal film.
History Taking (Surgical Presentation)
Focused surgical history from a Virtual Patient — acute abdomen, lumps and hernias, vascular limb, urological, breast or trauma presentations. Elicit red flags, build a surgical differential and safety-net. Data-gathering and rapport, not a management viva. Voice-only: the candidate may verbalise what they would examine but cannot demonstrate it.
Information Giving & Consent
Explain a diagnosis or procedure and take Montgomery-standard consent for a common index general-surgical operation (appendicectomy, hernia repair, cholecystectomy, diagnostic laparoscopy, abscess incision & drainage, stoma formation). Convey benefits, material risks and alternatives, and check understanding with teach-back.
Breaking Bad News / Difficult Conversation
SPIKES-shaped communication encounter with a Virtual Patient or relative — a new cancer diagnosis, disclosure of a post-operative complication under duty of candour, an unexpected finding, or a distressed relative. Empathy, honesty and clear next steps.
Example scenarios
A sample of the scenarios you will practise — each plays out as a live, spoken conversation, not a script to read.
“This is the femoral triangle. Name its boundaries and contents, tell me what lies immediately medial to the femoral vein, and explain what you would be at risk of damaging during an emergency femoral embolectomy.”
“A 68-year-old is 24 hours post-emergency laparotomy for a perforated sigmoid. He is oliguric, lactate 4.8, base excess −7. Walk me through your interpretation of his acid–base picture and your resuscitation.”
“A 34-year-old woman is listed for a laparoscopic cholecystectomy for symptomatic gallstones. Explain the operation and take consent, including the material risk of bile-duct injury and conversion to open.”
“A 60-year-old man's staging CT after a resected colon cancer shows new liver metastases. Break this news to him and answer his questions.”
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 5 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.
