Practice for the MRCEM Primary examination — 180 single-best-answer questions on the RCEM basic sciences curriculum, with adaptive AI question selection, spaced repetition and per-distractor rationales on every question.

MRCEM Primary — formerly FRCEM Primary — is the entry examination of the MRCEM, administered by the Royal College of Emergency Medicine (RCEM). It assesses the basic sciences underpinning emergency medicine, mapped to the RCEM Basic Sciences Curriculum and the Emergency Medicine 2021 Curriculum.
The exam is a single paper of 180 single-best-answer questions over three hours, delivered by computer at Pearson VUE centres worldwide. There is no negative marking, and the pass mark is set by the Angoff method, so it varies slightly between sittings.
The defining feature of this exam is its weighting: anatomy and physiology carry 120 of the 180 marks — two-thirds of the paper. Questions wrap a short emergency department scenario around a precise basic-science point: which nerve is injured in this fracture, which vessel is damaged, which receptor mediates this drug's effect.
Sittings run at published dates through the year. Eligibility, fees and the exam calendar are on the official website — always confirm current details at rcem.ac.uk before applying.
180 single-best-answer questions in one 3-hour paper, weighted heavily to anatomy and physiology.
Who applies: Doctors with a primary medical qualification pursuing the MRCEM — UK and Irish emergency medicine trainees and international EM doctors alike.
Entry point: Primary is the first of the three MRCEM components and can be planned early in postgraduate training.

RCEM publishes the mark allocation per subject (out of 180). AiMedQs coverage mirrors this distribution.
60 marks — upper and lower limb nerve injuries, cranial nerves and foramina, airway and cricothyroidotomy landmarks, thoracic and abdominal anatomy, the safe triangle, circle of Willis and cord lesion patterns
60 marks — cardiac cycle and Starling mechanics, oxygen-haemoglobin dissociation, V/Q and dead space, renal and acid-base physiology, endocrine axes, neurophysiology and pregnancy physiology
24 marks — pharmacokinetics, induction agents and neuromuscular blockers, local anaesthetic maximum doses, vasoactive drug receptor profiles and the antidotes table
17 marks — pathogens by site of infection, antibiotic mechanisms and spectrum, infection control and UK notifiable diseases
13 marks — acute and chronic inflammation, healing and repair, and the principles of neoplasia
6 marks — sensitivity, specificity and predictive values, study design recognition and bias

An intelligent study platform built for the RCEM basic sciences examination.
Question coverage mirrors the published mark allocation — anatomy and physiology at 60 marks each, then pharmacology, microbiology, pathology and EBM.
Every basic-science point is wrapped in an emergency department scenario, exactly as the real paper frames it — trauma, resus and acute presentations.
Our engine identifies your weakest subjects and prioritises questions there, so your study time goes where the marks are.
Drug mechanism, dosing and antidote answers follow the BNF and UK conventions — rINN names, SI units and UK reference ranges throughout.
Every answer is anchored to a named reference. See something off? Write us and we answer with the reference.
Adjacent nerves, arteries and same-class drugs are exactly where marks are lost — so every distractor gets its own explanation.
Missed questions return at scientifically optimised intervals, so fine-grained anatomy holds until exam day.
MRCEM Primary is unlike any clinical exam — it is a basic-science paper with an emergency medicine accent. General question banks miss what actually decides the result:
120 of 180 marks sit in two subjects. Fine-grained applied anatomy — nerve courses, foramina, landmark procedures — is tested at a precision generic banks never reach.
Stems look clinical but ask which structure, pathway or receptor — shoulder dislocation to axillary nerve, humeral shaft fracture to radial nerve, RSI drug to receptor profile.
BNF-consistent drug facts, rINN names (adrenaline, lidocaine), SI units and UK notifiable disease lists — details that differ from US-framed material.
The antidotes table, cranial nerve foramina, the safe triangle and cricothyroidotomy landmarks are finite, reliably examined content — ideal for spaced repetition.
AiMedQs questions are written to the RCEM blueprint with ED-context stems, named references and per-distractor rationales — so your preparation matches how the paper actually examines.

MRCEM Primary (formerly FRCEM Primary) is the entry examination of the MRCEM, run by the Royal College of Emergency Medicine (RCEM). It assesses the basic sciences that underpin emergency medicine — anatomy, physiology, pharmacology, microbiology, pathology and evidence-based medicine — mapped to the RCEM Basic Sciences Curriculum and the Emergency Medicine 2021 Curriculum.
The exam is a single paper of 180 single-best-answer questions taken over three hours, delivered by computer at Pearson VUE test centres worldwide. There is no negative marking. The pass mark is set by the Angoff standard-setting method and therefore varies slightly from sitting to sitting.
RCEM publishes the mark distribution: anatomy 60 marks, physiology 60, pharmacology 24, microbiology 17, pathology 13 and evidence-based medicine 6, out of 180. Anatomy and physiology together carry two-thirds of the paper — you cannot pass this exam on clinical knowledge alone. AiMedQs coverage mirrors this weighting.
Stems are short — typically a one-to-four-line emergency department scenario followed by a mechanistic question: which nerve is injured, which artery is damaged, which receptor mediates the drug effect, which organism is most likely. Distractors are adjacent structures or same-class drugs, so precise knowledge is what separates a pass from a fail.
Doctors pursuing the MRCEM — emergency medicine trainees in the UK and Ireland, and international emergency medicine doctors seeking the Royal College's membership qualification. Eligibility requires a primary medical qualification; check the current requirements and exam calendar at rcem.ac.uk before applying.
Applied anatomy of the injured patient dominates: the brachial plexus and upper-limb nerve injuries, cranial nerves and skull foramina, airway and cricothyroidotomy landmarks, the chest drain safe triangle, and the circle of Willis. Physiology favours cardiovascular and respiratory mechanics, acid-base interpretation, and the renal and endocrine control systems behind resuscitation decisions.
Primary tests mechanism; the Intermediate SBA tests management. On Primary you are asked which structure, pathway or receptor explains the finding. On the SBA you are asked what to do next for the patient. Preparing for one is poor preparation for the other, which is why AiMedQs keeps separate banks for each.
AiMedQs provides a growing, referenced MRCEM Primary question bank in the exam's single-best-answer format, weighted to the published blueprint, with adaptive AI question selection that targets your weakest subjects, spaced repetition, per-distractor rationales and performance analytics. Every answer is anchored to a named reference — if you think a keyed answer is wrong, write to us and we answer with the reference.
The MRCEM Primary bank is new and growing, with referenced questions added continually across the six blueprint subjects. We deliberately publish carefully sourced questions rather than inflating the count — every question carries a named reference and per-distractor explanations.
Candidates proceed to the MRCEM Intermediate SBA (a clinical, management-focused written paper) and then the MRCEM OSCE. Completing all three earns the MRCEM — the Royal College of Emergency Medicine's membership qualification, used in UK emergency medicine training and widely recognised internationally.
