Common MRCP PACES Mistakes

UK guide to common MRCP PACES mistakes: timing, physical signs, structure and patient concerns, with practical fixes for trainees.

Common MRCP PACES mistakes are usually not gaps in rare knowledge. They are execution errors: a six-minute examination that is not systematic, overcalling signs you did not find, a textbook differential that does not fit the patient in front of you, or forgetting to deal with the patient’s real question. In the current exam, those errors matter because you are judged across seven skills and still need both skill-level passes and an overall pass.

Why these mistakes matter

The current PACES format uses five stations and eight encounters. Stations 1 and 4 each pair a 10-minute Communication encounter with a 10-minute examination encounter, Stations 2 and 5 are 20-minute Consultation encounters, and Station 3 covers cardiovascular and neurological examination. That structure rewards candidates who can switch gears quickly rather than perform one polished routine over and over.

Official MRCP(UK) preparation material makes the marking logic very clear: you are assessed on Skills A to G, and the official pass rules still require a minimum standard in each skill as well as a minimum total score. Recent 2025 performance data also show that Skill B, identifying physical signs, had the lowest pass rate, while the neurology encounter produced the largest gap from the maximum score. In other words, bedside discipline and sign interpretation are still where many candidates come unstuck.

Common MRCP PACES mistakes in the examination stations

Looking busy instead of being systematic

Examiners are not rewarding theatre. For Skill A, the official reasons for not passing include examining in a non-systematic way, using incorrect technique, and missing significant parts of the examination. In the examination encounters you also need to finish the physical examination within six minutes, so a rambling routine is not just untidy; it is unsafe for your score.

A better approach is to make your examination visibly structured. If you are asked to examine the cardiovascular system in a 45-year-old with exertional dyspnoea, your pace should say that you know what matters here. Expose properly, inspect with purpose, examine fluently, then stop and present only the findings you truly elicited.

Guessing signs to fit the diagnosis

This is one of the classic common MRCP PACES mistakes. The official preparation page says unsatisfactory performance in Skill B is one of the most common reasons for not passing, and the May 2026 candidate advice is blunt: do not report signs you cannot find simply to fit a presumptive diagnosis. If you think the apex is displaced or the spleen is enlarged, be ready to say exactly why. If you cannot find it, say so calmly.

Examiners usually trust a candidate who says, 'I did not elicit a parasternal heave' more than one who offers a long list of invented positives. Your presentation should sound like bedside medicine, not wishful thinking.

Examining through clothes or forgetting dignity

MRCP(UK) specifically warns that examining through clothing is unprofessional and may attract unsatisfactory scores for Skill A. The same guidance also stresses adequate exposure while maintaining dignity, because patient welfare is marked explicitly as Skill G. This is not an etiquette extra. It is part of the mark scheme.

A simple bedside script helps: ask permission, expose only what you need, keep the patient warm, and reposition clothes or sheets before you present. Small acts of professionalism are highly visible in PACES.

Communication and consultation mistakes that lose easy marks

Treating the communication station like a monologue

In the Communication encounters at Stations 1 and 4, marks are based on examiner observation of your interaction with the patient, relative, or surrogate; there is no examiner-candidate questioning during the 10-minute encounter. In the Consultation stations, you have up to 15 minutes with the patient and then five minutes of examiner discussion. Candidates who use the same style in both settings often struggle.

In a Communication encounter, think structure and clarity. Start by checking what the person already knows, explain in short chunks, pause, and look for emotion as well as content. In a Consultation encounter, gather information with purpose, do a focused examination, then pivot early into synthesis rather than using all 15 minutes to collect data.

Wasting the five-minute reading time

MRCP(UK) repeatedly tells candidates to use the pre-encounter reading time carefully. The official advice is to read the written material, be clear about the task, plan the interview, and make notes you can take in with you. A surprising number of candidates skim the stem, spot one buzz phrase, and enter the room with the wrong agenda.

Use those five minutes to answer three questions before you walk in:

  • Who am I in this scenario?
  • What exactly has the exam asked me to do?
  • What concern is most likely to surface?

That takes 30 seconds. It can save the whole station.

Missing the patient’s actual concern

Skill F exists for a reason. Official prep guidance says candidates lose marks here by not exploring concerns, talking over the patient or relative, failing to check understanding, and simply running out of time before inviting questions. The May 2026 candidate advice adds another useful point: when a concern is raised, address it as soon as it appears rather than saving it for your closing script.

Picture a 67-year-old with new atrial fibrillation who asks, 'Am I going to have a stroke?' If you reply, 'I’ll come to that later,' and continue your checklist, you may never recover the mark. Examiners are listening for whether you noticed the worry, named it, and responded in plain English.

Forgetting to close the station

Many otherwise strong candidates open well and middle well, then fade. In the Communication encounters, official advice specifically tells you to sum up what has been agreed and confirm a way forward so that examiners can judge your clinical judgement. If your last two minutes are vague, you waste good earlier work.

A dependable closing framework is:

  • brief summary of the problem
  • what you think is happening or what needs to happen next
  • check questions or concerns
  • safety-net or agreed follow-up

Short. Clear. Finish line visible.

Differential diagnosis and clinical judgement errors

The common mistake here is giving a textbook list instead of a patient-specific differential. MRCP(UK) says candidates fail Skill D by giving a poor differential, missing the right diagnosis, or offering a broad list that is not relevant to the patient just assessed. Candidates fail Skill E by suggesting inappropriate investigations or management, or by building a sensible plan for the wrong diagnosis.

When examiners ask for a differential, they are not asking how many conditions you can name. They want to hear whether you can rank likelihood from the history and findings you personally obtained. Try this structure:

  • most likely diagnosis first
  • two or three realistic alternatives
  • one or two discriminating features that separate them
  • immediate investigations or management linked to the leading diagnosis

For example, after a focused consultation on leg swelling and breathlessness, 'decompensated heart failure' is stronger than a list containing nephrotic syndrome, liver disease, venous insufficiency, DVT, pulmonary hypertension, constrictive pericarditis, and hypothyroidism without any ranking. Specificity sounds senior.

Exam-day habits that quietly drag your score down

Some errors are not medical at all. Candidates lose marks by carrying frustration from one encounter into the next, by ignoring exact examiner questions, or by letting anxiety turn them vague. The official preparation page explicitly advises you to treat each encounter as new, use the five minutes to reset, and remember that examiners are trying to draw out evidence of your skills rather than trip you up.

Watch for these patterns:

  • starting to examine before you have properly understood the task
  • presenting findings before you are sure what you found
  • answering a different question from the one the examiner asked
  • spending too long on data gathering and too little on synthesis
  • using specialist jargon the patient would not understand
  • leaving concerns until the final seconds
  • forgetting comfort, exposure, or patient position
  • sounding apologetic and unsure even when your reasoning is correct

The practical takeaway is simple: slow the first 15 seconds down, then work with intent. Most PACES errors begin with a rushed start.

Practice workflow

A good PACES practice week does not need to be glamorous. It needs to be specific. Build your rehearsal around the official skills and current station timings, not around vague comments like 'be more confident'. One mock PACES circuit or mock viva-style oral drill with real timing is worth far more than another evening of passive reading.

A practical loop looks like this:

  • Bedside signs session: examine one or two real patients and force yourself to state both positive and absent findings.
  • Timed consultation drill: use an official sample scenario, take five minutes to read, then do a full 15-minute patient interaction and five-minute discussion.
  • Communication drill: practise one explanation station with a colleague, senior, or AI role-player, focusing on chunking information and checking understanding.
  • Marksheet debrief: score yourself against Skills A to G using the official marksheets, then name one behaviour to change next time.
  • Feedback review: if you have sat the exam before, use the detailed result breakdown in MyMRCP(UK) and target the weakest skill rather than just 'doing more PACES'.

If you use AI for practice, make it play one role at a time: patient, relative, or examiner. Then compare its feedback against the official skill domains. AI is useful for repetition. It is less useful if you let it invent a mark scheme.

Common mistakes to stop this week

  • Overcalling physical signs because the diagnosis seems obvious.
  • Performing a beautiful but overlong examination that collapses at six minutes.
  • Giving a generic differential instead of a ranked, patient-specific one.
  • Forgetting to ask, 'What is your main concern today?'
  • Leaving no time to summarise and agree a plan.
  • Speaking to the patient as if they were an examiner.
  • Missing dignity and comfort while focusing on technique.
  • Practising cases without an explicit Skill A-G debrief.

Summary

  • The biggest common MRCP PACES mistakes are failures of execution, not usually failures of obscure knowledge.
  • Skill B remains a high-yield weakness, so deliberate practice in identifying and not inventing signs matters.
  • In communication and consultation stations, patient concerns must be noticed early and handled clearly.
  • Differentials and management plans must fit the patient you have just assessed, not the textbook chapter you revised.
  • The fastest way to improve is to practise with official timings, official scenarios, and official skill domains.
