How to prepare for the RCGP SCA: a practical guide

The Simulated Consultation Assessment is the clinical component of the MRCGP — the exam that tests whether a GP registrar can consult safely and well, rather than whether they can answer questions about consulting. If you have spent your training being assessed on written knowledge, sitting an exam made entirely of live, timed consultations can feel like a different sport. This guide sets out what the SCA actually involves, how a circuit is marked, and how to prepare for it sensibly.

What the SCA actually tests

A full SCA circuit is 12 simulated patient consultations in one sitting. Before each case you get 3 minutes to read the record extract, then 12 minutes to consult. Cases are delivered remotely — most as a video consultation, and some as a telephone call with no video, exactly as they do on the day. Consulting well without being able to see the patient is a distinct skill, and it is worth practising deliberately rather than discovering it for the first time in the exam.

Because a circuit samples this many consultations back to back, it tests something single case-based teaching cannot: whether you can reset your focus quickly, keep your timing under control when a case runs away from you, and hold a consistent standard from the first case to the last.

How a circuit is marked

Every case is graded in three domains: Data Gathering and Diagnosis, Clinical Management and Medical Complexity, Relating to Others. Clinical Management and Medical Complexity carries a weighting of ×1.5, because it maps to more of the curriculum than the other two domains — so a warm, well-structured consultation with a thin management plan still comes up short. It is worth practising with that weighting in mind rather than treating all three domains as equally forgiving.

Importantly, the RCGP passes the circuit, not the individual case. Marks are combined across the whole sitting, so one case that goes badly does not fail you outright — it is one input into an overall result, not a verdict on its own. The RCGP does not publish a single fixed pass mark either: it sets the mark for each sitting using borderline regression, a statistical process that accounts for how that particular circuit performed, rather than a number fixed in advance.

What the RCGP’s feedback statements are (and are not)

When a case falls short in a domain, candidates are shown feedback drawn from the RCGP’s own published list of 26 statements — eight for Data Gathering and Diagnosis, nine each for the other two domains — in the college’s own wording rather than a paraphrase of it. It is worth knowing how the RCGP itself frames these: they are explicitly not performance indicators, they play no part in the marking, and candidates who pass the SCA receive them too. That framing is exactly what makes them useful to prepare against — each one names something specific that was missing from a consultation, which is a far more actionable thing to work on than a single grade.

How to prepare for the SCA

None of what follows is clinical advice — it is exam technique, the same kind that applies to any consultation-based assessment. What changes performance in a circuit like this is mostly about timing discipline and consistency rather than knowing more medicine.

• Practise out loud, against a real clock, rather than rehearsing an answer silently in your head — the skill being tested is a live, spoken consultation under time pressure.
• Use the 3-minute reading time to plan your approach to the case, not to second-guess the diagnosis before you have spoken to the patient.
• Practise telephone-only consultations separately from video ones. Without visual cues you have to work harder to build rapport and check understanding, and that only becomes comfortable with repetition.
• Give the management plan the attention its weighting deserves — a good history that ends in a vague or incomplete plan costs marks in the domain that counts for the most.
• Rehearse a consistent structure you can fall back on under pressure: a clear opening, systematic data gathering, explicit reasoning, a specific management plan, and a safety-net before you close.
• Review feedback by domain rather than by headline result, and take one specific thing to work on into your next practice case rather than trying to fix everything at once.
• Run several cases back to back at least once before the real sitting. A single case tells you what you can do; a full 12-case run tells you whether you can still do it on case 12.

This is exactly what ZWIP is built for on the SCA side: full 12-case circuits with AI simulated patients, run to the exam’s own 3-minute reading and 12-minute consulting clock, across both video and telephone cases, graded against the three domains above with the RCGP’s own feedback statements after every case that falls short.
