Expert take: what MRCS Part B really tests
MRCS Part B is an OSCE, so it is a completely different test from the written Part A: around 20 timed stations split between Applied Knowledge (anatomy, pathology, applied science, critical care) and Applied Skills (communication, history-taking, procedures). You must pass both components separately, and anatomy stations are heavily weighted — so a candidate strong in knowledge but unrehearsed in communication can still fail.
Preparation tips
- Rehearse skills stations aloud (communication, history, procedures) — reading is not enough.
- Build strong surgical anatomy; it is heavily weighted in the knowledge stations.
- You must pass both components, so do not neglect either.
Common mistakes to avoid
- Treating it like a written exam and only reading rather than rehearsing OSCE stations.
- Under-practising communication stations and failing the skills component.
MRCS Part B study plan
A phase-by-phase roadmap from your first concept to test-ready. Stretch or compress each phase to fit the time you have before your attempt.
- Rebuild surgical anatomy and applied surgical science for the knowledge stations

- Start OSCE-station practice early
- Rehearse communication, history-taking and clinical/procedural stations aloud
- Practise the timed, one-station-at-a-time OSCE format
- Get feedback from peers or courses on your station technique
- Do full OSCE-circuit practice under time
- Ensure you can pass both the knowledge and skills components
- Consolidate anatomy, the highest-yield knowledge area
