Most candidates need six to twelve weeks of focused preparation for PLAB 1, depending on starting knowledge and study hours per day. If you can study full-time, six to eight weeks is realistic; if you're revising alongside a job, plan for twelve. PLAB 1 is 180 single-best-answer questions in three hours with no negative marking, set at the level of a UK Foundation Year 2 doctor and mapped to the 2026 MLA content map — so a good plan is less about reading everything and more about disciplined question practice across three phases: foundation, volume and mocks.
Key takeaways
- 6–12 weeks of focused prep suits most candidates; the GMC frames PLAB 1 as F2-level applied knowledge, not fact recall.
- Full-time study → 6–8 weeks; revising around work → ~12 weeks.
- Structure every plan in three phases: foundation (learn), volume (drill), mocks (simulate).
- Question practice with proper review beats passive reading — there's no negative marking, so never leave a blank.
- An adaptive bank that resurfaces your weak topics saves time you don't have.
How long do you need to study for PLAB 1?
There is no single right answer, but the realistic range is six to twelve weeks of focused preparation. The GMC's own guidance points to roughly three to six months for candidates starting from a lower base or studying part-time, while a recent graduate revising full-time can be exam-ready in six to eight weeks. The variables that matter are your baseline knowledge, your hours per day, and how recently you sat finals — not raw calendar time.
Pick your timeframe
Match the plan to the hours you can genuinely commit. These are working targets, not rigid rules.
| Timeframe | Realistic hours/day | Questions/day | Best for |
|---|---|---|---|
| 6 weeks | 4–5 | 60–80 | Full-time study, recent graduate |
| 8 weeks | 3–4 | 50–60 | Full-time but starting from a lower base |
| 12 weeks | 2–3 | 30–40 | Revising alongside work or placements |
The three phases of a PLAB 1 plan
Phase 1 — Foundation (learn the framework). Work systematically through the MLA content map, system by system, doing questions topic-by-topic and reading around each. The goal here is coverage and understanding, not speed.
Phase 2 — Volume (drill and consolidate). Increase your daily question count, switch to mixed-topic sets, and review every wrong answer until you understand why the right answer is right. This is where most marks are won.
Phase 3 — Mocks (simulate the exam). In the final stretch, do timed, full-length mocks to build speed and stamina — 180 questions in three hours is as much a test of pacing as of knowledge. Use each mock to find your last weak areas.
Which plan should you choose?
- Short on time and studying full-time? See the PLAB 1 in 6 weeks plan.
- Working full-time? See how to study for PLAB 1 while working, built around shifts.
- Want a high-yield-first approach? Start with the high-yield PLAB 1 topics.
How do you use a question bank inside the plan?
A question bank is the engine of the plan, not a supplement to it. Three principles make it work: prioritise coverage of the content map over raw volume, review every wrong answer properly rather than moving on, and let an adaptive system resurface your weak topics so you spend time where it counts.
This is where iatroX fits a time-pressured plan: its adaptive engine targets your weakest areas rather than marching through questions in a fixed order, its Socratic Tutor works through the reasoning behind a question rather than just showing the answer, and Ask iatroX lets you check any management step against UK guidance (NICE, CKS, SIGN and the SmPC) — particularly useful if you trained under different national guidelines. iatroX covers PLAB 1 and UKMLA on one subscription (£29/month or £99/year), with free sample questions to start.
Frequently asked questions
How many hours a day should I study for PLAB 1? Between two and five, depending on your timeframe — around 4–5 hours/day for a six-week plan, or 2–3 hours/day spread over twelve weeks if you're working. Consistency matters more than marathon days.
How many questions should I do before PLAB 1? Aim for broad coverage of the MLA content map with thorough review, rather than a fixed number. Most well-prepared candidates work through several thousand practice questions, but reviewing your mistakes is what moves your score.
Is three months enough to prepare for PLAB 1? Yes, comfortably for most candidates — three months allows a steady foundation phase, a solid volume phase and time for mocks. Six to eight weeks is achievable with full-time study.
Does PLAB 1 have negative marking? No. There is no negative marking, so you should attempt every question — never leave a blank, even if you're guessing between two options.
How is the PLAB 1 pass mark decided? There is no fixed percentage. The GMC sets the pass mark for each sitting using the Angoff method, so it reflects the difficulty of that paper; historically it falls around 115–120 out of 180.
