The MRCEM Intermediate SBA sits between the Primary and the OSCE on the route to RCEM membership, and it has a reputation for catching candidates out. Pass rates have hovered around 45–50% historically, dropping to roughly 31% in 2024. Strong MRCEM Intermediate preparation is what separates a first-time pass from a resit.
Introduction to MRCEM Intermediate preparation
The MRCEM Intermediate SBA is a computer-based exam delivered by RCEM through Surpass Assessments at test centres in the UK and internationally. It runs as two papers of 90 single best answer questions each, two hours per paper, with a one-hour break in between. That’s 180 questions and four hours of writing time in total.
Every question is mapped to the Specialty Learning Outcomes (SLOs) for Years 1–3 of the 2021 Emergency Medicine Curriculum. There's no negative marking. The pass mark is set per sitting using the modified Angoff method plus one standard error of measurement, so it shifts slightly based on question difficulty.
Effective MRCEM SBA preparation starts with this in mind. You're not being tested on isolated facts but on clinical reasoning across the breadth of emergency medicine. Memorising answers won't carry you. Applying them under time pressure will.
Start with the right foundation
Confirm your eligibility early
You need to have passed MRCEM Primary, hold a primary medical qualification accepted by the GMC, hold current full medical registration with a licence to practise, and have at least two years of post-graduation medical experience before sitting. IELTS Level 7 is the expected standard of English.
Check your eligibility before you commit to a sitting. Application windows are short (just seven days, opening at 10am UK time and closing at 4pm on the deadline) and late applications aren't accepted. Seats at overseas centres also tend to fill quickly.
Build a realistic timeline
Most candidates who pass first time give themselves three to six months of structured revision. Less than that, and you're relying on existing clinical exposure to cover gaps. More than six, and motivation tends to dip before exam day.
Block out study time honestly. If you're working full ED rotas with on-calls, two focused hours on a workday and a longer block on rest days is more sustainable than ambitious daily targets you'll miss. The candidates who pass are those who study consistently throughout the months leading up to the exam.
Map the syllabus to your calendar
Print the SLO blueprint from RCEM and split it across your revision weeks. Don't revise in the order the curriculum is written. Instead, revise in the order that matches the blueprint weighting.
Trauma, cardiology, paediatrics and respiratory medicine carry the heaviest question weight at MRCEM SBA level. Combined, they make up the bulk of any sitting. Niche areas, such as ENT, ophthalmology, and dermatology, appear but rarely in proportion to the time some candidates spend on them.
A workable structure for MRCEM Intermediate exam prep is to cover the heavyweight specialities first, while your energy is highest, then layer the smaller specialities into the gaps. Keep one weekend per month free for a full-length mock and review.
MRCEM SBA preparation: where to focus your revision
High-yield topics
The areas that reward depth on MRCEM Intermediate SBA preparation tend to be the same year on year:
-
ACS and arrhythmia recognition
-
Major trauma: primary survey decisions, trauma in pregnancy, paediatric trauma
-
Paediatric emergencies – sepsis recognition, fever pathways, common presentations
-
Acute respiratory failure, asthma, COPD exacerbations
-
Toxicology – paracetamol, salicylates, tricyclics, opioids
-
Sepsis and the deteriorating patient
-
ECG interpretation under time pressure
-
Common surgical presentations: appendicitis, bowel obstruction, AAA
Build study notes against these as a priority. The exam rewards candidates who can read a scenario, identify the diagnosis, and pick the next correct management step. Being able to recite guidelines from memory without applying them will not help you.
The topics candidates underestimate
Three areas catch candidates out more often than they should. Ophthalmic and ENT emergencies appear in small numbers but are easy marks if you've done the reading. Mental health presentations under the Mental Capacity Act and Mental Health Act come up consistently and are often answered from a clinical instinct that turns out to be legally wrong. Procedural sedation, safe discharge criteria and end-of-life decisions in the ED are similarly under-revised.
Spend a weekend on these midway through your prep.
How to study for the SBA format
Single best answer questions aren't testing whether you know facts. What they are doing is testing whether you can choose between four or five plausible options under pressure. That should change how you study.
Read each stem actively. Identify the diagnosis first, then read the options. If you can't name the diagnosis, the question is unanswerable on knowledge alone. Instead, you’ll be guessing at pattern matching, which is unreliable.
When you get a question wrong, write down why. Not "I didn't know it." That's not useful. Was it a knowledge gap? A misread stem? Two plausible answers where you picked the wrong one? Track the categories. Most candidates have a pattern, and once you see yours, you can target it.
Build a question practice routine
Question banks are the highest-yield single resource for MRCEM exam preparation. They give you exposure to the format, calibrate your timing, and surface gaps faster than reading textbooks.
A practical pattern that works for most candidates:
-
Early prep (months 3–6 out): topic-by-topic blocks, no time pressure, full review of every explanation
-
Mid prep (months 1–3 out): mixed blocks of 30–60 questions, tutor mode, reviewing only the ones you get wrong or guess
-
Final month: timed blocks of 90 questions matching one paper of the real exam
Don't skip the explanations on questions you got right. Plenty of correct answers come from elimination rather than knowledge, and those are the ones you'll lose on a harder sitting.
Use mock exams to test your stamina
Four hours of SBA questions is physically demanding. By question 150 of a real sitting, candidates routinely report the words blurring together. Reading speed drops, and careless errors creep in.
The fix is exposure. Sit at least two full-length mocks in the last six weeks of your prep, in conditions that match the real exam. That means sitting at a desk, no phone, the full timed window with a one-hour break. Eat what you plan to eat on the day. Drink what you plan to drink.
The point is finding out where your concentration breaks and training through it.
Repeat and review
The biggest mistake in MRCEM SBA preparation is mistaking time spent on questions for progress. Doing 5,000 questions without reviewing them carefully gets you a worse result than 2,000 questions reviewed properly.
After every block, spend at least as long on review as you did on the questions themselves. Build a personal weak-topics list and revisit it weekly. If you get the same question type wrong twice, it’s highlighting a gap in your underlying understanding, and you need to read around it before moving on.
The final two weeks
The last fortnight is for consolidation rather than new material. Stop opening textbooks. Stop starting topics you haven't seen.
Focus on:
-
Your personal weak-topics list
-
Two full timed mocks under exam conditions
-
Light review of high-yield areas the morning after each mock
-
Sleep – eight hours, every night
Candidates who cram the night before consistently underperform what their question-bank scores predicted. You need to trust the work you've done.
On exam day
Eat before the first paper and bring water. The hour-long break between papers is enough to clear your head if you use it properly. Walk outside if you can, eat something light, and don't open notes.
Pace yourself at 80 seconds per question. That gives you about 10 minutes at the end of each paper to revisit flagged questions. If you don't know an answer, flag it and move on. There's no negative marking, so it is better to leave nothing blank when you make a final pass at the end.
If a question feels familiar but you can't pin down the answer, your first instinct is usually right. Don't talk yourself out of it without a reason.

Frequently asked questions
How long should MRCEM Intermediate preparation take?
Most candidates spend three to six months of structured revision alongside clinical work. Less than three months is achievable if you're already working in emergency medicine and have strong foundations, but it's tight.
How many questions should I practise before the exam?
There's no magic number, but candidates who pass typically work through 2,500–4,000 SBA questions across their prep. That includes a full review of explanations, not just answers. Volume without review doesn't translate to a pass.
Is MRCEM Intermediate harder than MRCEM Primary?
Pass rates are lower for the Intermediate SBA, particularly in recent sittings. The Primary tests basic sciences applied to emergency presentations. The Intermediate tests clinical decision-making across the full breadth of the 2021 EM Curriculum, which is a wider and less predictable scope.
Do I need a course, or are question banks enough?
Most candidates pass with a question bank, the RCEM curriculum and structured self-study. Courses can help if you're struggling to build a study plan or want examiner-led teaching on exam technique, but they're not a requirement.
What happens if I fail?
You can sit the MRCEM Intermediate up to six times. Previous attempts at the FRCEM Intermediate SAQ after August 2016 count towards this total. RCEM provides feedback on weak SLO areas, and that should shape your next round of prep.
