TL;DR — No. The FRCEM SBA does not use negative marking. Wrong answers score zero, exactly the same as a blank — so leaving a question blank is mathematically the worst move you can make. Always commit an answer, even if it is a complete guess. RCEM confirms it in writing: “a correct answer is awarded one mark and an incorrect answer is awarded nil, negative marking does not apply.”
If you are mid-paper, finger hovering over option C, asking whether to risk it or move on — risk it. This article gives you the regulation, the maths behind why guessing always beats blanks, and a 30-second triage you can run on any question you cannot crack on knowledge alone.
Does the FRCEM SBA have negative marking?
No. The FRCEM SBA is marked +1 for correct, 0 for incorrect, and 0 for unanswered. There is no deduction for a wrong answer and no bonus for leaving a question blank. The Royal College of Emergency Medicine (RCEM) states this on the official FRCEM Exams page:
“The FRCEM SBA is machine marked, a correct answer is awarded one mark and an incorrect answer is awarded nil, negative marking does not apply.”
That single sentence — confirmed again in the 2025 FRCEM Exam Regulations — controls every guessing decision you make on exam day. If a question is scored identically whether you guess wrong or skip it, the expected value of an unanswered question is zero and the expected value of any guess is greater than zero. Always guess.
Key facts (plain text)
- Correct answer: +1 mark
- Incorrect answer: 0 marks
- Unanswered (blank): 0 marks
- Negative marking: not applied
- Paper structure: 180 single best answer (SBA) questions, two papers of 90, two hours each, one-hour break
- Source: RCEM — FRCEM Exams page and FRCEM Exam Regulations 2025
So should I guess every question I cannot answer?
Yes — unconditionally. Because there is no penalty for a wrong answer, an unanswered question is a guaranteed zero whereas a guess gives you somewhere between a 20% and 100% chance of a mark depending on how much of the stem you can use. The only rational strategy is to leave nothing blank.
Expected value of a guess on a five-option SBA:
- Blind guess (no eliminations): 1 / 5 = 0.20 marks per question
- Eliminate 1 option: 1 / 4 = 0.25 marks per question
- Eliminate 2 options: 1 / 3 = 0.33 marks per question
- Eliminate 3 options: 1 / 2 = 0.50 marks per question
- Blank: 0 marks per question
Over 180 questions, random guessing alone on every skipped item would on average recover roughly 36 marks you would otherwise leave on the table. In a criterion-referenced exam where pass marks typically land in the 110-130 region, that is the difference between resit and certificate.
How does FRCEM SBA scoring compare to other UK and international exams?
FRCEM SBA sits alongside almost every modern UK postgraduate medical exam: no negative marking. The pattern is consistent across the Royal Colleges and reflects current best practice in psychometrics — negative marking penalises risk-aversion and disadvantages candidates from cultures where guessing is discouraged.
| Exam | Negative marking? | Correct | Wrong | Blank | Guessing rule |
|---|---|---|---|---|---|
| FRCEM SBA | No | +1 | 0 | 0 | Always guess |
| MRCEM SBA | No | +1 | 0 | 0 | Always guess |
| MRCEM Primary | No | +1 | 0 | 0 | Always guess |
| MRCP(UK) Part 1 & 2 | No (equated scoring) | +1 | 0 | 0 | Always guess |
| MRCS Part A | No | +1 | 0 | 0 | Always guess |
| USMLE Step 1/2/3 | No | +1 | 0 | 0 | Always guess |
| PLAB 1 | No | +1 | 0 | 0 | Always guess |
If you trained on legacy exams that did deduct marks — some international postgraduate papers still use formula scoring — you may have built a “skip if unsure” reflex. Unlearn it for the FRCEM SBA. The reflex is actively costing you marks.
What about questions I genuinely run out of time on?
Spend the last 90 seconds of each paper carpet-bombing unanswered items with your best single guess. Pick one letter — say, C — and apply it to every blank, then review only the ones you have time to read properly. Pure-random letter assignment on ten unanswered questions has an expected return of two marks, non-trivial when the pass mark hinges on single integers.
Why a single letter rather than alternating? The act of choosing wastes seconds you do not have. Just pick a column and move. The mark-recovering move is just answering, not the choice of letter.
The Surpass test centre interface flags unanswered questions in the review screen, which makes carpet-bombing trivial. Use the flag function for items you want to revisit, but every flagged item must still have a provisional answer locked in — flagging without answering is a guaranteed zero if time runs out. See our deep-dive on the FRCEM SBA flagging strategy (mark and return).
How is the pass mark actually set if there is no penalty for guessing?
The FRCEM SBA uses the modified Angoff method plus one Standard Error of Measurement (SEM). It is criterion-referenced — there is no quota of candidates who pass or fail. Either every candidate could pass, or every candidate could fail, depending on performance against a fixed standard.
The process, summarised from the RCEM Angoff Explained document:
- A panel of subject matter experts — practising EM consultants who train and write exam questions — rates each item independently.
- For each item, each judge estimates the proportion of minimally competent candidates who would answer it correctly. Judges anchor their rating to a hypothetical candidate just on the borderline of fellowship-level practice.
- Judges discuss disagreements, then ratings are averaged per item.
- Item Angoff scores are summed across all 180 items to produce the total Angoff score for the paper.
- One SEM, calculated from the specific cohort sitting that diet, is added to the Angoff total.
- The result is rounded to the nearest integer — that is your pass mark.
Because both the Angoff score and the SEM vary between diets, the pass mark varies between diets. There is no fixed percentage. RCEM also reserves the right to remove items post-exam if a quality issue is identified during adjudication; in that case both the maximum and the pass mark are recalculated, and removal is only ever applied where it benefits candidates.
Are wrong answers and unanswered questions treated differently for failed candidates?
No. The mark scheme is identical for everyone — pass, fail, top scorer, bottom scorer. There is no penalty multiplier, no separate “guessing index”, and no algorithm that treats a guess differently from a knowledge-based answer. Your raw score is simply the count of correct answers out of the items remaining after any post-exam quality adjustments.
Some candidates worry their guessing pattern could be flagged as suspicious. It cannot. The Surpass platform records timing and answer changes for security purposes, but those data are not used to weight individual items in scoring. A correct answer is a correct answer regardless of whether it was the product of three minutes of clinical reasoning or a 4-second educated guess.
What is a smart 30-second triage when I am stuck on a question?
Use a three-step elimination drill before committing. The whole drill should take under 30 seconds — anything longer and you are robbing time from questions you actually know.
- Cross out the obviously wrong. In an SBA built around “single best answer”, at least one and often two options are designed to be distractors that fail on a single discriminating feature in the stem. Strike them through mentally.
- Re-read the lead-in sentence only. Not the whole stem — just the final question. SBAs are often won or lost on a single qualifier like “most likely”, “next investigation”, “definitive management”, or “initial step”.
- Pick the option that is hardest to argue against. Best-answer questions reward the option that is defensible across the most plausible interpretations of the stem, not the option that is theoretically perfect for one narrow reading.
If you are still split between two answers, commit to the one that is more conservative clinically — SBAs are written by examiners who default to RCEM curriculum guidance, which tends toward the cautious end of management. Then move on.
Does the no-negative-marking rule apply to both papers and to the OSCE?
Yes for both SBA papers, but the FRCEM OSCE is a different beast entirely. The same +1/0/0 rule applies to every question in both 90-question papers. There is no separate threshold per paper — your total score across the 180 items is what counts, against the pass mark for that diet.
The FRCEM OSCE — 16 eight-minute stations plus rest stations — uses domain-based marking with a pass mark set by borderline regression plus 1 SEM. Guessing strategy is irrelevant in the OSCE; performance is assessed live by examiners against domain criteria, and you have to pass at least one resuscitation station in addition to clearing the overall cut score. Do not carry SBA guessing reflexes into your OSCE practice.
How do I build the “always answer” reflex during revision?
Train the way you sit. When you do timed question banks, force yourself to commit a final answer on every single item — even ones you intend to flag for review. If you let yourself skip questions in practice, you will skip them in the exam.
A practical drill for the final two weeks before sitting:
- Set timed blocks of 90 questions in two hours, matching paper length.
- Hard rule: every question must have an answer locked in before you move on, even if you re-flag it.
- Track time-to-answer on “unsure” items. If it creeps above 90 seconds on items you got wrong anyway, you are over-deliberating.
- In the last 10 minutes of every practice block, scan back for any item without an answer and assign one. Make this muscle memory.
Frequently asked questions
Does the FRCEM SBA have negative marking?
No. RCEM marks correct answers +1 and incorrect answers 0, with no deduction. Negative marking does not apply.
Should I guess on the FRCEM SBA?
Yes — always. A guess has positive expected value on a five-option SBA (0.20 marks blind, more with elimination); a blank is a guaranteed zero. There is no scenario in which leaving a question blank is the optimal move.
What happens to unanswered questions on the FRCEM SBA?
They score zero, identical to a wrong answer. The mark scheme makes no distinction between “didn’t try” and “tried and got it wrong”. Both are zero marks.
Are wrong answers counted differently for borderline candidates?
No. The mark scheme is the same for every candidate regardless of overall performance. Your raw score is the count of correct answers against a pass mark set by Angoff plus 1 SEM.
If I am between two options, how do I choose?
Pick the option that is hardest to argue against given the lead-in qualifier (“most likely”, “next step”, “definitive”). When still split, go with the more conservative clinical option. Commit and move on.
Is the FRCEM SBA pass mark a fixed percentage?
No. The pass mark is set per diet using the modified Angoff method plus 1 SEM, then rounded to the nearest integer. Both inputs vary between sittings, so the pass mark varies too.
Can I be penalised for guessing patterns the system flags as suspicious?
No. Surpass logs timing and answer changes for exam security, but those data do not affect individual item scoring.
Does negative marking apply to the FRCEM OSCE?
The OSCE is domain-marked by live examiners with a pass mark set via borderline regression plus 1 SEM, plus the requirement to pass at least one resuscitation station. The no-deduction principle holds, but guessing strategy is irrelevant in a viva-style assessment.
If items are removed after the exam for quality issues, does that hurt my score?
No. RCEM only removes items where doing so is in the candidates’ interest. When an item is removed, both the maximum and the pass mark are recalculated. Removal usually pushes the pass rate up.
How many questions can I afford to guess and still pass?
There is no fixed number — it depends on your accuracy on the items you do know. Guessing never makes your situation worse than leaving an item blank.
Should I change my answer if I get a gut feeling on review?
Only if you have identified a specific reason — a misread qualifier, a fact you recalled, a stem feature you missed. Pure gut-feeling changes are, on average, neutral to slightly negative.
Where can I see the official RCEM statement on FRCEM SBA scoring?
The wording appears on the RCEM FRCEM Exams page under “How is the exam marked and standard set?” and in the FRCEM Exam Regulations 2025 PDF on the Exam Regulations & Policies page.
