Key points

  • PLAB 2 is 16 scenarios, each 8 minutes — you must train time checkpoints.
  • Win by structure: open → focused Hx → targeted exam/explanation → plan → safety net.
  • Treat every station as a ‘safe FY2 GP/ward doctor’ performance.

Official format (don’t freestyle this)

PLAB 2 is a clinical and professional skills assessment made up of 16 scenarios, each lasting 8 minutes, designed to reflect real-life settings such as a mock consultation or acute ward. Train exactly to that constraint.
The biggest PLAB 2 mistake is trying to be exhaustive. The exam rewards safe, structured practice: you identify risk, prioritise the likely diagnosis, propose an appropriate plan, and communicate it professionally. The timer is the exam.
1

Checkpoint 0:00–0:45 — Frame the station

Read carefully. Decide: is this primarily communication, acute safety, chronic management, or admin? Pick the top 3 differentials and top 3 red flags before you speak.
2

Checkpoint 0:45–2:30 — Open + focused history

Open question → clarify → focused questions that discriminate your top differentials. Use ‘one question per differential’ and explicitly ask the key red flags for that presentation.
3

Checkpoint 2:30–4:30 — Examination or explanation

If physical exam: do a clean, clinically sensible targeted exam with signposting. If no exam: explain your working, summarise, and transition to management.
4

Checkpoint 4:30–7:00 — Management (safe + proportionate)

Immediate actions (if needed) → investigations (only what changes management) → first-line treatment → follow-up. If unsure: escalate appropriately — that’s often the ‘safe’ answer.
5

Checkpoint 7:00–8:00 — Safety net + close

Give specific red flags and what to do. Confirm understanding. Document/summary to examiner if required. Finish cleanly, not rushed.

Station mantra

“Safe, structured, proportionate.” If you’re torn between an elegant rare diagnosis and a safe common one, the safe common one wins unless the stem screams otherwise.
  • Top 3 differentials + top 3 red flags decided before you open your mouth.
  • Explicit safety-netting with timeframe and action.
  • Escalation used appropriately (and confidently).
  • Time checkpoints rehearsed until automatic.
