Key points
- Part A is a five-hour SBA exam split into a 3-hour paper and a 2-hour paper.
- Build stamina: long timed blocks are a requirement, not optional.
- Debrief by module and by error type (knowledge vs process).
Official exam constraint
MRCS Part A is a five-hour MCQ (single best answer) exam consisting of two papers: a 3-hour morning paper and a 2-hour afternoon paper, taken on the same day.
Part A is as much an endurance exam as it is a knowledge exam. The typical failure mode is inconsistent accuracy late in the day. You fix that with (1) stamina training and (2) a strict triage rule so you don’t burn your brain on low-probability questions.
1
Step 1 — Two-pass triage becomes non-negotiable
Pass 1: secure what you know fast. Pass 2: return to flagged items. Train this in every session so it’s automatic when fatigue hits.
2
Step 2 — One long simulation every week (minimum)
In the last 4–6 weeks, weekly long simulations are mandatory: you’re training accuracy under fatigue, not just recall in comfort.

Step 3 — Debrief by ‘repeatable mistake’
Log your top errors: anatomy confusion, physiology mechanism, imaging misread, operative principle misapplied. Convert each into a ‘rule’ or a flashcard, then re-test weekly until the error disappears.
- Weekly long simulation completed (stamina training).
- Two-pass triage rehearsed in all timed blocks.
- Top 30 repeating errors tracked and re-tested weekly.
- Late-paper accuracy monitored (are you fading?)
