In MRCOG Part 3 structured discussions, the safest way to answer is to open with immediate priorities, branch into clear decision paths, and close with a short summary plan. That suits the current station design: a structured discussion is examiner-led, lasts 12 minutes including two minutes of reading time, and can evolve as the examiner prompts you or adds new information.
RCOG describes a 14-task Clinical Assessment, with each task assessing three or four domains drawn from patient safety, communication with patients and relatives, communication with colleagues, information gathering, and applied clinical knowledge. In practice, that means examiners are listening for a safe, prioritised clinical response, not a textbook monologue.
Why structure matters in this station
Candidates usually lose marks here by trying to prove everything they know at once. The answer becomes broad, slow, and hard to follow. A clear structure lets the examiner hear your judgement early.
That matters even more because the examiner can move the task on. If you have already stated your priorities, your branches, and your likely plan, each new question becomes an update to your framework rather than a derailment.
A good answer sounds like a registrar thinking aloud on a busy shift: safe first, focused next, clear end point.
A simple framework for MRCOG Part 3 structured discussions
Use a three-part shape:
- Open with the main problem and your first priorities.
- Branch into two or three clear pathways.
- Close with a decision, escalation, and follow-up plan.
It is simple enough to use under pressure and flexible enough for obstetrics, gynaecology, safeguarding, ethics, consent, or complaints.
Open with priorities, not background detail
Your first 20 to 30 seconds should tell the examiner where you are starting clinically. Don't begin with a long differential unless the scenario genuinely calls for it.
A strong opening usually contains four things:
- the main clinical concern or immediate risk
- the first practical actions
- the key information you need now
- who else you would involve early
For example, if the stem suggests sepsis in pregnancy, a strong opening might sound like this:
"My immediate concern is maternal sepsis and potential deterioration. I would start with urgent ABC assessment, full observations, IV access, bloods including cultures, and early senior obstetric and anaesthetic input. Once initial stabilisation is underway, I would assess fetal wellbeing and identify the likely source of infection."
Notice what this does. It sounds safe. It sounds decisive. It gives the examiner a map.
If the task is communication-heavy rather than resuscitation-heavy, the same principle applies. Your opening may be, "My priority is to understand her concern, check whether there is any immediate clinical risk, and then explain the situation clearly before discussing options." That still shows structure.
Branch your answer into tracks
Once you have opened, don't drift into one long stream. Split the rest of the answer into tracks the examiner can follow.
Useful branches include:
- unstable vs stable
- maternal issues vs fetal issues
- diagnosis vs immediate management vs ongoing plan
- clinical management vs communication and documentation
- today's decision vs follow-up and safety netting
Short signposting phrases help a lot:
- "If she is haemodynamically unstable, I would..."
- "Assuming she is stable, my next steps are..."
- "I would separate this into immediate management, investigation, and longer-term planning."
- "There are maternal and fetal aspects here."
- "From a communication point of view, I would..."
A reduced fetal movements example shows this well:
- Open: "My first concern is fetal compromise, so I would assess maternal observations, confirm gestation and risk factors, and arrange immediate fetal assessment."
- Branch 1: "If the assessment is abnormal, I would escalate urgently and move toward senior review and delivery planning as appropriate."
- Branch 2: "If the assessment is reassuring, I would review the wider risk profile, explain the findings, give clear advice about recurrence or deterioration, and arrange follow-up."
That sounds much better than listing every possible investigation and management option in no clear order.
Close with a management position
Many candidates never really finish. They keep talking until the examiner stops them. A better close tells the examiner what you have decided, who knows, and what happens next.
Your close should usually contain:
- your working diagnosis or main concern
- the immediate plan
- escalation or referral
- what you would explain to the woman or family
- documentation, review, and safety-netting
A useful closing line is:
"To summarise, my priority is to stabilise her, exclude immediate life-threatening causes, and involve the appropriate senior team early. I would explain the plan clearly, document the discussion and decisions, and review her response before moving to definitive management."
That is not just tidy. It is exam-smart. If you are interrupted halfway through your close, the examiner has still heard your end point.
How to stay structured when the examiner changes the stem
In structured discussion tasks, the examiner may use prompt questions, give you further information as the scenario develops, and sometimes build depth through linked tasks. So your answer has to be flexible rather than memorised.
The key rule is simple: answer the new question first, then reconnect it to your framework.
For example:
- "That new information makes ectopic pregnancy more likely, so my priorities change to urgent reassessment of stability and escalation for definitive management."
- "If her observations are now abnormal, I would move from outpatient-style assessment to emergency management."
- "Building on the earlier scenario, my concern now is whether she understands the risk and whether there is a safe agreed plan."
When the examiner interrupts, don't panic and restart from the top. Just place the new information into one of your branches.
A good mental script is:
- What has changed?
- Does it change risk?
- Does it change urgency?
- Does it change the plan I already outlined?
If you can say that out loud in crisp language, you sound calm and clinically credible.
What examiners tend to reward
They are usually listening for whether you can prioritise, communicate, and make workable decisions. In this exam, communication and safety are not side issues. They are built into the assessed domains.
That means your answer should regularly make space for:
- escalation to senior or multidisciplinary support
- what you would say to the woman or family
- consent, shared decision-making, or capacity where relevant
- safeguarding, dignity, and inclusion where relevant
- documentation and handover
The Curriculum 2024 materials describe Part 3 as assessing the application of knowledge, clinical competencies, and attitudes in practice rather than factual recall alone. That is why structured answers score better than encyclopaedic ones.
Common mistakes
- Opening with a full history when the stem already signals an emergency.
- Listing every differential before stating the immediate risk.
- Forgetting to separate maternal and fetal priorities in obstetric scenarios.
- Answering only the medical part and ignoring communication.
- Saying "senior review" without saying why, when, or by whom.
- Giving a vague ending such as "I would manage with the MDT".
- Failing to adapt when the examiner gives new information.
- Sounding scripted rather than responsive.
Practice workflow for mock viva training
Do not rehearse only polished full answers. This station is interactive, so your practice has to include interruption, redirection, and changing information.
RCOG's official preparation resources include revision courses with circuit practice and video demonstrations of structured discussions, plus eLearning that reflects a 14-task Part 3 circuit and its marking approach. Use those resources to calibrate tone and pacing, not to memorise scripts.
A practical weekly workflow looks like this:
- Pick 3 short stems from different areas: one obstetric, one gynaecology, one communication or ethics task.
- Give yourself 2 minutes to read and 90 seconds to deliver only the opening.
- Repeat the same stem and add the branches.
- Repeat again and force yourself to produce a clean close in 20 seconds.
- Ask a study partner to interrupt you twice with new information.
- Debrief with three questions: Did I state the risk early? Did I branch clearly? Did I finish with a plan?
Once a week, run a longer mock viva of 4 to 6 stations. Record it if you can. Most candidates improve fastest when they hear how often they hedge, ramble, or fail to close.
RCOG has also announced ongoing Part 3 development work through 2025 to 2026, with a future-facing exam model planned for 2027. So before your sitting, re-check the official format page and any exam updates rather than relying on old course notes.
Summary
- Open with the main risk and your first priorities.
- Branch into two or three clear tracks the examiner can follow.
- Close with a decision, escalation, and follow-up plan.
- Adapt visibly when new information appears.
- Practise under interruption, not just in polished monologues.
