· About this exam ·
The ACEM Primary Examination

The ACEM Primary Examination tests the basic science foundations of emergency medicine: physiology, pharmacology, anatomy and pathology. Passing it is a prerequisite for entering the ACEM Fellowship training pathway. The written component is 150 MCQ and EMQ questions; candidates who pass then sit four integrated vivas, each covering all four disciplines through a single body-system theme. Approximately 65% of candidates pass at each sitting.

  • OrganiserAustralasian College for Emergency Medicine (ACEM)
  • FormatWritten paper (150 MCQ/EMQ), followed by 4 integrated vivas for candidates who pass the written component
  • DomainsPhysiology (~45%), Pharmacology (~30%), Anatomy (~15%), Pathology (~10%)
  • SittingsTwice yearly, typically May (written) and October (written), with vivas approximately one month later
  • Pass rateApproximately 65% per sitting (written component); viva pass rates are higher for those who reach it
Standard candidate reading
  • Standard medical physiology references at registrar level

Frequently asked
Yes. Each session picks one body-system theme and then probes you across all four disciplines in sequence: anatomy, physiology, pharmacology, then pathology. The timer runs for 20 minutes total, with approximately 5 minutes per discipline. You get a per-discipline debrief at the end with a tier and a specific learning point for each phase.
They're written in single-best-answer format, curriculum-mapped to the April 2017 ACEM Primary syllabus across all four disciplines. The AI generates new questions without repetition, so the supply is effectively unlimited. Each question includes a full explanation for every option including the distractors.
Practising written answers builds the structured basic science knowledge that the written and viva components both test. The grader gives you specific feedback on whether your physiology mechanisms are correct, whether you've quantified your values, and whether you've made the clinical connection to emergency medicine; all of which are common failure points in the real exam.
