How PLAB 2 Is Scored: The Three Domains Examiners Mark You On

Most candidates walk into PLAB 2 knowing the medicine and not knowing the marking. That's backwards — the marking scheme is public knowledge, and understanding it changes how you prepare. Here's how the exam actually scores you, in plain language.

The format in one line

Sixteen stations, eight minutes each, a simulated patient in most of them, an examiner watching in silence. Around three hours door to door.

The three domains

Every station marks you on the same three things:

1. Data gathering, technical and assessment skills. Did you ask the right questions, in a sensible order, and pick up the clues? This is your history-taking structure and examination technique. It's where a systematic approach (think SOCRATES for pain, red-flag screens, ICE) earns steady marks.

2. Clinical management skills. Did you reach a sensible working diagnosis and do the safe thing next? Investigations, immediate treatment, referral, and — the one candidates forget under pressure — safety-netting. Telling the patient exactly when to come back is a management mark, and it's missed constantly.

3. Interpersonal skills. Did the patient in front of you feel heard? This is rapport, plain-English explanations, responding to emotion, checking understanding. It is worth just as much as the other two domains, and it's the one that separates candidates who know medicine from candidates who pass.

Notice what this means: a station where you nail the diagnosis but steamroll the patient can score worse than one where you're clinically ordinary but structured, safe, and human.

How the pass mark works

There's no fixed "60% to pass". The GMC sets a cut score for each station based on examiner judgements of borderline performance, adds them up across the exam, and adds a small statistical buffer. You also need to pass a minimum number of individual stations — so you can't ace half the circuit and coast through the rest. Two practical consequences:

• Consistency beats brilliance. Twelve solid stations beat six perfect ones and ten disasters.
• A bad station isn't fatal. Everyone bombs one. The candidates who fail are the ones who carry that station into the next three. Reset at every door.

What this means for your preparation

If three domains are marked equally, your practice time should look like that too. Most people spend 90% of their time on clinical knowledge — the domain they're already strongest in — and rehearse interpersonal skills almost never.

The fix is deliberate, repeated role-play with feedback against a marking scheme. For example:

• Data gathering under pressure: acute chest pain or thunderclap headache
• Management and safety-netting: COPD exacerbation or anaphylaxis
• Interpersonal skills: breaking bad news or the angry relative

Every OSCEPilot station scores you against all three domains after each attempt, so you can see exactly which domain is leaking marks — which is the information the exam itself will never give you until results day. A free account includes three full sessions a month.

The short version

Sixteen stations, three domains, equal weight. Structure your consultations, safety-net every patient, treat the actor like a human being, and reset between stations. The exam is designed to let a safe, structured, kind doctor pass — so practise being exactly that, out loud, against the clock.
