Failing PLAB 1 is common enough to deserve a structured resit plan rather than shame. The most important shift since the exam was aligned to the MLA content map is this: repeating recall lists can improve your recognition of familiar questions without improving your UK decision-making — and it is decision-making that the longer, more clinical vignettes now test.
PLAB 1 remains a 180-question single-best-answer paper sat over three hours, still run and labelled as PLAB by the GMC, and offered in February, May, August and November. It is now built on the MLA content map of roughly 430 conditions organised around clinical presentations, the same standard a UK graduate meets at finals. The practical consequence is that the exam rewards candidates who can choose the most appropriate next step in a UK context, not those who can only recognise a memorised stem.
The failure modes to look for
| Failure mode | What it looks like | How to fix it |
|---|---|---|
| Recall dependence | You know the answer only when the question is familiar | Fresh blocks; reason from the stem, not memory |
| Pathway gaps | You miss the UK "next step" in management | Practise the decision against current NICE/CKS pathways |
| Medication safety gaps | Contraindications and interactions catch you out | Targeted prescribing-safety blocks |
| Weak high-yield areas | Paediatrics, obstetrics and mental health drag the score | Dedicated blocks in those areas |
| Command-word errors | You answer a different question to the one asked | Highlight the command word before answering |
| Timing pressure | The last stretch of 180 questions is rushed | Timed blocks and a per-item pacing rule |
The resources worth using honestly
PLABable is the recognised incumbent for many IMGs and is a strong choice for PLAB-specific exposure, volume and familiarity with exam themes. PassMedicine, Pastest and Quesmed all offer broader UK-finals-style practice that is useful now that PLAB shares the MLA standard. The GMC's official practice papers are essential whatever else you use, because they are written by the exam setters. None of these is the problem; doing questions without converting the misses into UK reasoning is.
Your seven-day plan
Day 1. Identify your weak domains and whether timing hurt you. Day 2. Run a diagnostic block mapped to the MLA content map. Day 3. Re-work your wrong areas from your main bank, debriefing each miss properly. Day 4. Drill guideline thresholds where management items caught you out. Day 5. Focus a block on prescribing and safety. Day 6. Sit a timed 100–180 question block to rebuild pacing. Day 7. Set your resit date and build a six-week plan around your weak presentations.
Where iatroX fits
iatroX is most useful after a PLAB 1 failure as the layer that converts recall into reasoning. Its UKMLA-aligned bank is free and adaptive, so it can find related weaknesses across presentations rather than only flagging the topics you already know are weak. When you flag a question you "only knew because you'd seen it," the Socratic Tutor asks what would change the answer — a different age, a different observation, a contraindication — so you rebuild the underlying decision rather than re-memorising a stem. Ask iatroX then settles the UK pathway from a sourced corpus (NICE, CKS, SIGN, NHS content) with citations, which is where so many "most appropriate next step" questions are won or lost.
The six-week resit plan
Beyond the first week, structure the run to your sitting around your weak presentations rather than a generic syllabus. Weeks one to two consolidate the diagnosed gaps. Weeks three to four broaden coverage across the content map, with prescribing and high-yield areas — paediatrics, obstetrics and mental health — getting dedicated blocks. Weeks five to six are timed full-length practice under realistic conditions, converting any remaining recalls into reasoned UK decisions. Keep the daily loop tight throughout: fresh questions, a proper debrief on every miss, and a guideline check where a management threshold caught you out.
A short FAQ
Will redoing recall questions get me through? It can lift recognition without lifting reasoning, and the longer vignettes now test reasoning. Convert recalls into UK decisions instead.
How long should I leave before the resit? Long enough to fix the diagnosed weakness and rebuild pacing — often around six weeks of consistent practice, sooner if the gap is narrow.
Is PLAB being replaced by a separate UKMLA exam for IMGs? No. PLAB remains the IMG route to the same MLA standard and is still called PLAB by the GMC.
