MRCEM SBA Revision
Top 10 Tips for Passing the MRCEM SBA Examination
The MRCEM SBA is the second written component of the Membership of the Royal College of Emergency Medicine examination. It assesses the full range of conditions and presentations encountered in the Emergency Department and is mapped to the Year 1–3 Specialty Learning Outcomes within the RCEM Curriculum.
The examination consists of 180 single best answer questions, divided into two papers of 90 questions. Each paper lasts two hours, with a one-hour break between them. This gives you more time per question than the MRCEM Primary, but the clinical scenarios are often longer and the decisions more nuanced.
The challenge is not simply learning facts. You need to recognise important presentations, interpret clinical information, apply current practice and choose the single most appropriate answer from several plausible options. These ten principles provide a practical framework for preparing effectively.
1. Start With the Curriculum and Examination Blueprint
Before beginning detailed revision, familiarise yourself with the RCEM Curriculum and the current MRCEM SBA examination blueprint.
The examination covers the assessment and management of undifferentiated presentations, resuscitation, trauma, paediatric emergencies, procedural knowledge and other challenging situations encountered in the Emergency Department. Use the blueprint to divide your revision into manageable sections and ensure your preparation reflects this breadth.
Use your question bank alongside the curriculum and examination blueprint. A strong question bank can guide your revision, identify weaker areas and help you apply knowledge in an exam-style format. Checking your progress against the official curriculum provides an additional safeguard against leaving less familiar topics uncovered.
Return to them throughout your preparation and mark topics as secure, developing or not yet covered.
2. Revise Clinical Decisions, Not Just Diagnoses
Recognising a diagnosis is often only the beginning. You may instead be asked for the most appropriate initial investigation, immediate treatment, next step or safe disposition.
When revising a presentation, work through its clinical pathway:
- What dangerous diagnoses must be considered?
- Which findings alter the patient's level of risk?
- What needs to happen immediately?
- Which investigation is most appropriate at this stage?
- What is the first-line treatment?
- Who can be discharged, and who requires admission or senior review?
Pay close attention to timing. The definitive treatment may not be the correct answer if the patient first requires resuscitation, analgesia, stabilisation or a more urgent intervention.
3. Keep Your Knowledge Aligned With Current Clinical Practice
The MRCEM SBA tests contemporary clinical practice. Management changes over time, and an approach learned at medical school or used in a previous healthcare system may not match the answer expected in the examination.
For important presentations, know the current principles of investigation, risk assessment and management, particularly in areas such as:
- Sepsis and antimicrobial treatment
- Acute coronary syndromes
- Stroke and transient neurological symptoms
- Venous thromboembolism
- Head injury and cervical spine assessment
- Asthma and other acute respiratory presentations
- Poisoning and overdose
- Paediatric fever and acute illness
You do not need to memorise every line of every guideline. Concentrate on thresholds for investigation, indications and contraindications, first-line treatments, escalation criteria and safe disposition.
When different resources disagree, check when they were written and verify the point against a current authoritative source. Outdated knowledge is particularly dangerous in an examination built around selecting the best current answer.
4. Give Resuscitation, Trauma and Paediatrics Proper Attention
Candidates often concentrate on familiar adult presentations, leaving important gaps elsewhere.
Resuscitation and trauma require a structured approach. You should be comfortable recognising immediate threats, deciding the correct sequence of interventions and distinguishing the priority action from treatments that may be required later. Revise the management of shock, cardiac arrest and peri-arrest states, major haemorrhage, airway emergencies, severe respiratory failure and common patterns of traumatic injury.
Paediatric Emergency Medicine also deserves dedicated revision. Normal observations, fluids, drug doses, patterns of injury, safeguarding concerns and thresholds for intervention vary with age. Revise the unwell child, neonatal and infant presentations, fever, respiratory illness, seizures, dehydration and common injuries.
Learn the relevant algorithms and principles, then practise applying them to clinical scenarios.
5. Practise Interpreting ECGs, Imaging and Clinical Data
The MRCEM SBA is not entirely text based. You may need to interpret an ECG, radiograph, photograph, blood gas or set of investigation results before answering the question.
Do not restrict practice to classic examples. The abnormality may be subtle and candidate accounts often describe examination images as harder than those in some revision resources. Use a consistent method rather than relying only on pattern recognition.
For each ECG or image:
- Review it systematically.
- Identify the important positive and negative findings.
- Relate those findings to the clinical scenario.
- Decide what the question is asking you to do with the result.
Remember that interpretation may only be the first step. An ECG may lead to urgent treatment, a radiograph may change disposition or a blood gas may reveal the need for ventilatory support. If an image is unclear, use the clinical context and answer options, but do not invent findings that are not visible.
6. Begin Questions Early and Study the Explanations
Do not wait until you have finished revising the curriculum before beginning question practice. The syllabus is too broad, and questions are one of the best ways to learn how clinical knowledge is converted into an SBA.
Begin with topic-based sets to identify gaps and connect related principles. As your knowledge develops, introduce mixed sets so that you must recognise the presentation and decision without being told the subject.
The number of questions completed matters less than the quality of the review that follows. After each set, ask:
- Why is the correct option better than the alternatives?
- What detail in the stem changes the answer?
- Was my error caused by missing knowledge, faulty reasoning or careless reading?
- Would the answer change if the patient were younger, unstable, pregnant or had an important comorbidity?
Candidate feedback suggests that the real examination can feel harder and less straightforward than routine question-bank practice. This is something we have worked particularly hard to address in our own question bank, with questions designed to test understanding and application rather than recognition of familiar wording.
Use the explanations to develop transferable knowledge that you can apply even when a question is presented in an unfamiliar way.
7. Learn How to Choose Between Two Reasonable Answers
Several options may be plausible, but one will be more appropriate in the precise circumstances. Two investigations may both be useful, but one should come first. Two treatments may be required, but one addresses the immediate threat.
When you are uncertain, return to the wording of the question:
- Is it asking for the most likely diagnosis or the most appropriate next step?
- Is the patient stable or unstable?
- Has an intervention already been performed?
- Is the question asking about immediate, initial or definitive management?
- Which option best fits this patient, at this point in their care?
Avoid adding facts that are not in the stem. Candidates sometimes talk themselves out of the best answer by imagining unusual complications or hidden information. Use the information provided and choose the option that is safest, most evidence based and most appropriate to the stated situation.
If two answers still appear possible, identify the clinical distinction being tested. This produces a more reasoned choice than guessing from familiarity.
8. Build an Error Log and Revisit Weak Areas
Incorrect answers are useful only if they change what you know or how you approach the next question.
Keep a concise record of recurring weaknesses. This might include a guideline threshold you repeatedly confuse, an ECG pattern you fail to recognise, a paediatric dose, an important contraindication or a distinction between two similar presentations.
Classify errors where helpful:
- Knowledge gap: you did not know the required fact or principle
- Application error: you knew the information but used it incorrectly
- Question-reading error: you missed an important word or time point
- Image-interpretation error: you failed to identify or use a finding
- Changed guidance: your previous understanding is no longer current
Keep entries brief. Your error log should become a personalised revision resource, not a collection of copied explanations. Revisit it regularly and reattempt related questions to ensure you can apply the principle in a different scenario.
9. Complete Mixed Sets and Full Two-Paper Mocks
Topic-based practice cannot fully reproduce the demands of the MRCEM SBA. In the real examination, you must move rapidly between adult and paediatric presentations, trauma, resuscitation, toxicology, mental health, imaging and procedural knowledge.
Introduce mixed timed blocks well before the examination. Later, complete full mock papers under realistic conditions. At least once, simulate the entire examination structure: 90 questions in two hours, a one-hour break and then a further 90 questions in two hours.
You have an average of 80 seconds per question. Some questions will take much less time, leaving room for more complex scenarios. Develop a pace that allows you to complete the whole paper without rushing the final section.
If a question is consuming too much time, make the best reasoned choice you can and move on. There is no negative marking, so every question should have an answer.
Use the break to eat, drink and reset. Avoid conducting a post-mortem on the first paper. You cannot change those answers, and carrying uncertainty forward only makes the next 90 questions harder.
10. Make Your Revision Sustainable and Clinically Connected
Most candidates prepare while working a demanding rota. Build your plan around consistent, realistic sessions. Short periods can be used for questions, error-log review or ECGs, with longer sessions reserved for unfamiliar topics and mock papers.
A useful structure is:
- Early phase: map the curriculum, revise core presentations and begin topic-based questions
- Middle phase: complete the remaining syllabus, strengthen weak areas and introduce mixed sets
- Final phase: concentrate on timed papers, image interpretation, recurring errors and rapid review of key decisions
Use clinical work as an additional learning opportunity. After a relevant case, review the investigation pathway, treatment and disposition. Remember, however, that local practice can vary and is not automatically the nationally accepted answer.
Protect sleep, take breaks and leave some flexibility in the plan. Sustainable preparation over several months is more dependable than relying on an exhausting final burst.
Final Thoughts
The MRCEM SBA tests both breadth of knowledge and the ability to apply it to real Emergency Department decisions. Start with the curriculum, revise presentations as clinical pathways and keep important management aligned with current practice. Begin questions early, study the explanations and practise distinguishing the best answer from options that are merely possible.
As the examination approaches, move towards mixed practice and realistic two-paper mocks. The goal is not to memorise every possible scenario, but to build a broad, current and well-organised understanding that allows you to make the safest and most appropriate decision from the information provided.
