How to analyse mock exam performance FRCEM SBA

Facts last verified 30 May 2026.

You sat a mock. You got 67%. Now what? Most candidates close the laptop, feel vaguely demoralised, and go back to plodding through the question bank. That is wasted data. A properly debriefed mock is the single highest-yield study session you will do this revision cycle — published audit data on physician multiple-choice work suggests structured error reflection moves candidates 10–15% over a few cycles. The mock itself is the cheap bit. The debrief is where the score actually moves.

This guide gives you the exact debrief workflow used by FRCEM SBA candidates who turn an average first mock into a comfortable pass: a five-step process, an error category framework, a tracking spreadsheet template you can copy today, and a decision tree for translating findings into your next two weeks of revision.

TL;DR — the 5-step mock debrief

1. Score the paper but ignore the headline number for now. Log overall %, time used, and questions flagged or skipped.
2. Re-attempt every wrong question cold, before reading the answer. This separates “genuinely didn’t know” from “misread under time pressure”.
3. Categorise every error using the six-bucket framework below (knowledge gap, recognition failure, technique error, guideline error, statistics/critical appraisal, time/fatigue).
4. Map errors to SLOs and topics against the RCEM curriculum. Identify the 3–4 topics generating the most marks lost.
5. Build a 14-day action plan: one knowledge-block per weak topic, one technique fix, one re-test in 14 days on the same topic mix.

Read on for the full method, the tracking spreadsheet columns, and the FAQ.

Why does the raw percentage tell you almost nothing?

The pass mark for FRCEM SBA hovers around 60% in most sittings (it is set by Angoff standard-setting, so it moves a few points each diet). Knowing you scored 67% tells you almost nothing actionable. Two candidates can both score 67% and need completely different next steps:

• Candidate A ran out of time, flagged 22 questions, got 14 of those wrong. Their problem is pacing and decision-making under time pressure. More content revision won’t help.
• Candidate B finished with 25 minutes to spare, answered every question, and got 60 wrong — mostly in paediatrics, toxicology, and statistics. Their problem is content depth in three specific SLO areas.

Same headline number. Two completely different study plans for the next fortnight. The whole point of the debrief is to find out which candidate you are.

What should I do in the first 24 hours after a mock?

Resist the urge to look at the answers immediately. Do this in order:

1. Capture the raw data while it’s fresh — total time used, questions skipped, questions flagged, gut-feel confidence per section (paeds, trauma, resus, etc.).
2. Step away for a few hours. Don’t debrief tired. Cognitive fatigue is also why you got half of them wrong.
3. Re-attempt every wrong (and every flagged) question blind — with the answer hidden, no time pressure, full guidelines/notes available if you want. This is the single most important step. If you get it right second time without notes, the error was technique, not knowledge.
4. Only then open the answer key and the explanations.

This blind re-attempt is the move most candidates skip. It’s also the one that tells you what kind of mistake each wrong answer actually was.

The six error categories: how should I classify every wrong answer?

Every wrong answer fits one of these. Be ruthlessly honest — if you’re tempted to put something in “misread” for the fifth time in one paper, it’s probably a knowledge gap.

The split matters because each category needs a different fix. A candidate whose errors are 60% technique and 20% guideline doesn’t need another textbook — they need pacing drills and a guideline cheat sheet. Lumping everything into “need to revise more” wastes the diagnostic information the mock just gave you.

What columns do I need in my mistake-tracking spreadsheet?

Forget pretty — the spreadsheet just needs to be searchable and sortable. Use the columns below, one row per wrong question. After two or three mocks you can pivot on the “Category” and “SLO/Topic” columns and the weak spots become obvious in 30 seconds.

One sheet per mock, with a master sheet that pulls them all together for cross-mock analysis. Google Sheets, Excel, Notion table — the tool doesn’t matter. The discipline of filling it in does.

How do I map errors onto the FRCEM SBA blueprint?

The FRCEM SBA is structured around RCEM’s SLOs (Specialty Learning Outcomes) and the official RCEM feedback report gives you a per-SLO breakdown when you sit the real exam. Mock providers don’t always tag their questions by SLO, so you may need to do it yourself.

The high-yield SLOs to track:

• SLO1 — the undifferentiated patient (the biggest single chunk).
• SLO2 — the resus / critically ill patient.
• SLO3 — the injured patient.
• SLO4 — procedures.
• SLO5 — pre-hospital and end-of-life.
• SLO6 — safeguarding.
• SLO7 — teaching, leadership, evidence, ethics (where statistics and human factors live).

Plot your error count per SLO. If 14 of 30 errors are in SLO2, you have a resuscitation problem — not a general “need to read more” problem.

What does a good 14-day action plan look like?

The debrief is worthless without an output. After categorising every error, your output is a single page that looks roughly like this:

Repeat. Three of these cycles is enough to move most candidates from “borderline” to comfortable.

How do I separate knowledge gaps from technique errors when I’m being honest with myself?

This is the question candidates struggle most with. Self-diagnosis is hard because it’s comforting to label a knowledge gap as “I just misread it”. The blind re-attempt step is the test:

• Re-attempt the question with the answer hidden, no time pressure, no notes.
• Got it right? Probably technique — you knew the answer, the exam-day conditions tripped you up.
• Got it right with notes/guidelines open? Recognition failure or guideline gap — the knowledge is there but not retrievable under pressure.
• Still got it wrong even with notes? Pure knowledge gap. Read, flashcard, retest.

If you skip the blind re-attempt and go straight to the answer key, you’ll mis-classify half your errors, and your study plan will fix the wrong problem.

What about questions I got right — should I review those too?

Yes, but selectively. Flag any question where you got the right answer but weren’t confident — those are lucky guesses, not knowledge. Track them in the same sheet under category “guess-right”. If a topic keeps appearing in your guess-right column, treat it as a weak topic, even though the headline number says you got it right. Lucky guesses are knowledge gaps wearing a clever disguise.

How often should I sit a full mock?

For the 3–4 months before the exam, sit one full timed mock every 2–3 weeks. More often than that and you don’t have time to debrief properly and act on the findings. Less often and you don’t get the trend data. Day-to-day, do 30–60 untimed questions on your weak topics, but the timed mock is what tells you whether the technique work is sticking.

FAQ

What’s a good FRCEM SBA mock score to be aiming for at the halfway point?

If you’re three months out and consistently hitting 60% on full-length, mixed-topic mocks, you’re on track. Below 55% with three months left, you need to look hard at whether your knowledge base is broad enough or whether you’re mostly doing single-topic question sets that flatter your real performance. Above 70% three months out, you’re probably ready — focus on technique, weak spots, and not regressing.

Should I use multiple question banks or stick to one?

Stick mostly to one for breadth (RCEMLearning is the obvious default and the most representative), then dip into a second (FRCEM Tutor, Bromley Emergency, study FRCEM) for fresh questions in the final 6 weeks. Spreading thinly across three banks tends to mean none of them get finished properly. The exam doesn’t reward question-bank tourism — it rewards depth.

How do I avoid “feel-good” revision where I just re-do questions I already know?

Use the tracking spreadsheet. If you’ve got a question right twice in a row, archive it. Don’t allow yourself to re-do easy topics “to keep ticking over” — the time is better spent on the bottom three topics on your weak list. The dopamine hit of getting easy questions right is one of revision’s most seductive traps.

Is it worth doing the same mock paper twice?

Once for the debrief, yes. After 6–8 weeks have passed and you’ve forgotten the specific stems, you can re-attempt the same paper to test whether the topic-level learning has stuck. Sooner than that and you’re testing memory of the question, not the underlying knowledge.

How do I handle a mock score that’s much lower than expected without losing momentum?

Sit with the disappointment for 24 hours, then debrief mechanically using the framework above. A bad mock that’s thoroughly debriefed is more useful than a good mock you don’t look at. Most candidates who pass the FRCEM SBA had at least one mock in the 50s. The discriminator is what they did next.

What if my errors are evenly spread across topics rather than concentrated?

That usually means a technique or pacing problem, not a content problem. Look at your category breakdown — if categories 3 and 6 (technique and time/fatigue) account for >40% of errors, the fix is structured timed practice, not more reading. Time yourself ruthlessly: 90 seconds per SBA, no exceptions.

Do I need to track which specific distractor I picked, not just whether I was wrong?

Yes — for any question where you got it wrong with high confidence. Patterns in the wrong distractors you pick are diagnostic. If you keep picking the “most recent guideline” distractor when the question is testing the older standard, that tells you something. If you keep picking the most clinically tempting answer when the question is testing the safest one, that tells you something else.

How do I debrief a mock if the question bank doesn’t give detailed explanations?

Bin that question bank. Explanations are 80% of the value — without them, you’re testing without learning. Stick to banks where every question has a referenced explanation (RCEM guideline, NICE CKS, RCUK ALS, BNF). If the explanation is a single sentence with no reference, treat the question itself with suspicion.

How do I deal with topics I keep getting wrong even after multiple debrief cycles?

The cycle isn’t working — either you’re not relearning the topic properly or your initial diagnosis was wrong. Switch resources (if you’ve been using a textbook, watch a video module; if you’ve been watching videos, read the primary guideline). Get a study partner to quiz you verbally on the topic — speaking the answer is a different retrieval mode and exposes shaky knowledge fast.

Is it worth paying for a formal mock day with a tutor debrief?

In the final 6–8 weeks, yes — one tutor-led debrief tells you things about your technique that self-review cannot, particularly around the way you’re reading stems. Earlier than that, self-debriefing with the framework above is enough. Don’t spend money on three tutor mock days when one well-debriefed self-led mock would give you the same intelligence.

How do I know when to stop debriefing and just sit the real exam?

When you’ve done three consecutive mocks at or above 65%, in conditions that match the real exam (timed, mixed topics, no notes), and your category breakdown shows you no single error type accounts for >30% of your wrong answers. At that point, more mocks won’t make you sharper — rest and one final guideline refresh will.
