Common MRCOG Part 3 Mistakes

The common MRCOG Part 3 mistakes are usually obvious within the first minute: you have not stated the safety issue, you answer the stem you hoped for rather than the one in front of you, and you talk in one long burst instead of running a consultation. In this exam, safe prioritisation and clear communication beat a dense guideline recital.

That matters because the MRCOG Part 3 Clinical Assessment is a 14-task circuit built around five domains, and each 12-minute task samples three or four of them. You are not being judged on knowledge alone. A candidate who knows the topic but fails to gather the right information, explain risk, or escalate clearly can still look unsafe.

Why these mistakes cost marks

The assessment uses both simulated patient or colleague tasks and structured discussion tasks. A clinical examiner is present on all 14 tasks, a lay examiner features on four tasks, and the circuit may include linked tasks or a writing task. If your style is rigid, over-technical or poorly organised, several domains can fall at once.

Examiners are listening for something specific: can you make safe decisions, communicate them in the right register, and adapt as the scenario moves? The polished candidate sounds calm, selective and purposeful. The struggling candidate sounds busy.

Common MRCOG Part 3 mistakes that lose marks

You bury the safety issue

Candidates often open with background, definitions or a full differential when the station really needs an immediate safety frame. In an obstetric emergency stem, that sounds detached. In a counselling stem, it sounds as if you have not recognised what matters most to the patient.

A safer opening is brief and active. If the scenario is a 34-week patient with vaginal bleeding, say what you would prioritise now: maternal observations, fetal wellbeing, amount of bleeding, IV access, bloods, anti-D if relevant, and senior help if she is unstable. Then move to explanation and next steps.

You talk at the patient instead of consulting

A common failure pattern is the information dump. You know the facts about ectopic pregnancy, postpartum haemorrhage or postmenopausal bleeding, so you unload them all. The problem is that the station is not a mini-lecture.

Examiners want to hear that you can run a consultation. That means checking what the patient knows already, finding out what she is most worried about, explaining the immediate concern in plain English, and then giving a recommendation she can follow. Short chunks. Pause. Check understanding.

A useful test is this: if an actor could swap out three of your sentences and the station would sound exactly the same, you are probably giving a script rather than a consultation.

You use the same register for every station

Patient stations and colleague stations are not the same performance. With patients, unexplained jargon makes you sound cold or unsafe. With colleagues, vague reassurance and long counselling phrases make you sound indecisive.

For a patient, say severe blood pressure in pregnancy rather than launching straight into severe pre-eclampsia with end-organ risk unless you explain it clearly. For a registrar-to-consultant call, do the opposite: lead with the severity, the key observations, your working diagnosis, and what you need now.

Your plan is vague

I would escalate if concerned is not enough. Neither is I would involve seniors. The examiner is listening for threshold, timing and purpose.

Say who you are calling, why you are calling them, and what you need from them. For example: I am concerned this is severe pre-eclampsia. I would ask the consultant obstetrician to review immediately, start magnesium sulphate and antihypertensive treatment, send FBC, U and Es and LFTs, and plan delivery once the patient is stabilised. That sounds safer because it is specific.

You answer the case you wanted, not the task you were set

Some candidates read the stem, spot the topic, and then run their favourite answer. That is especially costly if the real task is narrower: obtain consent, explain uncertainty, speak to a colleague, or justify your next investigation.

Read the prompt for the verb. Explain. Counsel. Prioritise. Handover. Consent. If the circuit gives you linked tasks, carry forward the facts and decisions from the first task rather than starting from scratch. The published format also allows writing tasks, so be ready to shift gear without panicking.

You prepare for rumours, not the standard

Another mistake is chasing myths about a fixed pass score or a fixed pass rate. RCOG states that pass standards are set by standard setting and that there is no fixed quota, so trying to game the cut score is a poor use of revision time. Your job is simpler than that: produce repeated, clearly competent performances across stations.

How to structure stronger answers

A good answer usually has an obvious spine. The wording changes by station, but the structure should be easy for an examiner to follow.

For patient or relative tasks

Use a simple five-part arc:

open with introduction, agenda and any immediate safety check
gather the few facts that change urgency or risk
explain the likely problem in plain English
recommend a plan, including options where relevant
close with questions, safety-netting and next steps

For example, if a 29-year-old with pain and bleeding may have an ectopic pregnancy, a strong opening sounds like this: you acknowledge her anxiety, check for red flags such as severe pain, collapse or shoulder-tip pain, explain why urgent assessment is needed, and tell her what will happen next today. That is far better than reciting every investigation before you have shown concern.

For colleague tasks

Be brisk and ordered. An SBAR-style structure works well:

situation and urgency
relevant background and observations
assessment or working problem
recommendation and what you need now
contingency if the patient deteriorates

A strong example would be a call about a 37-week patient with headache, clonus and a blood pressure of 168 over 112. State the severity early, name severe pre-eclampsia as the concern, outline immediate treatment and monitoring, and make a clear request for senior review.

For structured discussions

Show judgement early. Give the likely diagnosis or main management problem, the immediate priorities, the key investigation or treatment decisions, and the points that would trigger escalation. Then adapt when the examiner adds new information.

This matters because structured discussion tasks are designed to test applied clinical knowledge in context, not whether you can recite a guideline chapter from memory.

Task-type traps in the MRCOG Part 3 Clinical Assessment

In simulated patient or colleague tasks, the interaction itself is part of the mark. If you bulldoze past emotion, fail to signpost, or never check understanding, you may sound clinically literate but consultation-poor. That is costly in a circuit where communication and information gathering are explicit domains, and where some tasks also include lay examiner input.

In structured discussions, the opposite problem appears: candidates wait passively for the next clue. A better approach is to show a working plan early, then adapt when new information arrives.

If the second task is linked to the first, do not reset the case from zero. Carry forward the risk profile, the uncertainties, the patient perspective and the management decisions you have already established.

Failure patterns to avoid

opening with a textbook introduction instead of the immediate risk
listing every differential instead of the most likely and the dangerous
using jargon with patients without translation
forgetting to explore ideas, concerns and expectations when the station is clearly a counselling task
saying you would escalate without naming who, when and why
ignoring the exact verb in the prompt
offering options without making a recommendation when a recommendation is needed
finishing without safety-netting or follow-up
sounding rehearsed enough that you stop responding to what the actor or examiner has just said

Practice workflow

Your practice needs to resemble the real exam. Build sessions around the published timing: 2 minutes of reading and 10 minutes of speaking within each 12-minute task. Score yourself against the same five domains the exam uses, not just knowledge.

A practical weekly rhythm looks like this:

two short midweek stations done under full timing
one weekend mini-circuit of four to six tasks
immediate debrief after each station with three headings only: missed safety point, poor phrase, better opening line
repeat of failed stations within 48 hours
one recorded station each week so you can hear your pace, jargon and interruptions

Use mixed practice. Do not spend all your time on emergency obstetrics if your counselling and colleague-handover stations are weaker.

Use official resources for calibration. RCOG lists revision resources for this exam, including an official recap course and eLearning material with interactive videos modelled on a 14-task circuit. Those resources are useful for checking whether your exam voice actually sounds patient-centred, structured and safe.

One final habit helps more than most candidates realise: after every mock, rewrite only your first two sentences and your final two sentences. That is where many stations are won or lost.

Summary

State the danger early. Do not make the examiner guess what worries you.
Match your language to the audience: plain English for patients, concise escalation language for colleagues.
Give specific plans with clear thresholds for senior review, treatment and follow-up.
Answer the exact task in the prompt, and carry information forward in linked stations.
Practise under real timing and debrief by domains, not by vague impressions.
