Extensive coverage across every topic
You are the ST4 in the ED and act as educational supervisor for Dr Sara Khan, an ST2 EM trainee. You have arranged a confidential meeting in the ED office at her request, after she opened a recorded-delivery letter from the GMC this morning informing her of an investigation under the Fitness to Practise (FtP) procedures.
The referral relates to a documentation entry Sara made nine months ago during a busy night shift on a 68-year-old man who re-attended 48 hours later with a missed posterior circulation stroke and significant residual harm. The Trust completed a PSIRF learning review (closed, system + individual factors identified). The family has now formally complained to the GMC.
Number Needed to Treat (NNT)
The number of patients you must treat to prevent one extra bad outcome.
The number of patients treated, over a defined period, for one of them to avoid one extra adverse event. NNT = 1 ÷ ARR (absolute risk reduction). Lower is better; NNT 1 means everyone benefits.
67 treated → 1 avoids the extra bad outcome
67 treated patients. Only the highlighted figure avoids the extra outcome because of treatment; the other 66 gain nothing from it.
Each figure is one patient treated for the trial's duration. The single highlighted one is the patient whose bad outcome is prevented. The bigger the crowd needed to colour in one figure, the weaker the treatment's real-world impact.
An impressive relative risk reduction can hide a tiny absolute benefit when events are rare. NNT re-anchors the effect to baseline risk — the fastest test of whether a “positive” trial should change ED practice.
NNT = 1 ÷ ARR (always round UP)NNH = the same maths, for harmCRASH-2 (Lancet 2010) — 20,211 trauma patients with, or at risk of, significant haemorrhage, TXA vs placebo. 28-day all-cause mortality 16.0% → 14.5% (RR 0.91) → NNT ≈ 67. Time-critical: TXA helps if given ≤3 h; given >3 h the subgroup had more bleeding deaths — the NNT only holds for early treatment.
A trial reports a 30% relative risk reduction. Can you calculate the NNT?
Answer: No — RRR alone isn’t enough; you need the absolute risk reduction (the control event rate), because NNT = 1 ÷ ARR.
Breadth across the whole syllabus, depth in every topic — and explanations that actually teach.
The deepest SBA bank in emergency medicine. Filter by SLO, topic or difficulty, and learn from explanations that show why the right answer is right — and why each distractor isn't.
Sit full mocks built to the FRCEM Final SBA format under exam conditions, then use themed mocks to target the SLOs where you're losing marks.
Exam-focused distillations of RCEM, NICE and other key guidance — the evidence base behind the questions, without the wading.
A complete OSCE station library — resus, procedures, communication and more — each with candidate instructions, a domain-weighted mark scheme and examiner pearls, mapped across all 20 FRCEM categories. Included in full with every EMF Premium plan.
Every question tagged to a Specialty Learning Outcome, so your revision mirrors the exam.
Rolling monthly, or a one-off 3- or 6-month pass — pick what matches your exam date.
Monthly renews until you cancel · 3 & 6-month passes are one-off · a fraction of the £429–£695 you pay per exam sitting
Breadth and pressure. The SBA papers can draw from the entire RCEM curriculum, every distractor is plausible, and you're answering 180 questions against the clock. Knowing the medicine isn't enough — you have to recognise it instantly and pick the single best answer under time. That's a different skill from clinical practice, and it's the one most candidates run out of time to build.
Because the exam doesn't test what you've read, it tests what you can apply in under a minute. A pass comes from reps: seeing hundreds of variations of the same decision until the right answer is reflex. EMF turns passive reading into active recall at the scale the exam actually demands.
One clear arc. Cover the whole syllabus across all 12 SLOs, drill the topics you're weakest on, then sit full timed mocks until exam conditions feel routine. Every question explains the reasoning as you go — so each session leaves you sharper, not just scored.
Yes — because you don't need to do all 40,000 questions, you need to do the right ones. Filter by SLO or topic to zero in on a weak area, then drill it with themed mocks built around a single subject. It's the fastest line from weak spots to confidence.
Every single SBA explains why the correct answer is correct and why each distractor is wrong, with the guideline source referenced. You're not memorising answer letters — you're learning the decision, so the knowledge carries over to questions you've never seen.
You target it deliberately. Every question is tagged to its Specialty Learning Outcome and topic, so you can filter straight to a weak area and drill it, then rehearse it under pressure with a themed mock. Your revision mirrors the exam blueprint instead of wandering through a textbook.
EMF covers both RCEM written papers — the MRCEM SBA and the FRCEM Final SBA. They sit at different stages of training: the MRCEM SBA tests core emergency medicine earlier on, while the FRCEM Final SBA is the broader, more advanced paper on the road to CCT. The bank spans the full range — from core MRCEM-level material to advanced FRCEM Final content — all built to the 2025 RCEM curriculum and tagged across the 12 Specialty Learning Outcomes.
Yes — the MRCEM SBA is covered, not bolted on. It tests core emergency medicine, and that material sits right inside the bank: the same 12 SLOs, the same explanations, the same guideline sourcing. You focus your revision by SLO and topic, so you're drilling MRCEM-level content rather than wading through the entire FRCEM Final syllabus. Dedicated MRCEM-format mock papers and exam-level filtering are on the way as we finish tagging the bank.
Depth. Spread across 130+ categories, it's broad enough to cover every corner of the syllabus and deep enough to drill a single weakness for hours without running out of fresh, exam-standard questions. Every SBA is curated by a UK emergency medicine consultant — so the volume is quality-controlled, not auto-generated filler.
Genuinely. There are 20 full mocks, each a 180-question timed paper built to the real FRCEM Final SBA format, so you walk into the real thing already used to its length, pace and pressure. Themed mocks let you rehearse the specific SLOs you find hardest.
Curated by a UK emergency medicine consultant and built to the 2025 RCEM curriculum, with explanations referenced to RCEM, NICE and other key guidance. It's updated regularly to reflect the latest guidance as recommendations change — so you're never revising from material that's quietly gone out of date. Eight clinical guideline ebooks distil that evidence base into exam-focused summaries: the source behind the questions, without the wading.
£29/month rolling (cancel anytime), or a one-off £59 for 3 months / £89 for 6 months. Every plan unlocks all 40,000+ SBAs, all 20 mocks, the full OSCE library and all 8 ebooks.
Yes — the two free guideline ebooks are open to everyone, and every product page shows exactly what is inside each plan. If you want to test-drive the full platform, the £29 monthly plan is the low-risk way in — cancel after a month if it isn't for you.
For most candidates it's the core of their revision: tens of thousands of explained SBAs, 20 timed mocks and the guideline ebooks, all in one place. Start on monthly for £29, see the quality for yourself, and stay only while it earns its keep.
Revise with the UK's largest EM question bank. Full access from £29 a month — or one payment for 3 or 6 months.
