PassMedicine is an inexpensive, high-volume PLAB 1 bank that many international graduates use as their core — and, as with its other exams, its dashboard measures how you are performing inside the app rather than whether you are ready for the GMC paper. This audit is for IMGs deciding how far to trust the numbers. The principal limitation: a self-directed practice loop rewards the domains you choose, and the GMC blueprint does not care what you chose to revise.
What PassMedicine offers for PLAB 1 right now
PassMedicine sells low-cost fixed-term PLAB 1 access on its standard model — a large single-best-answer bank, revision and timed modes, textbook notes and peer-comparison analytics. It does not advertise an LLM tutor or a machine-learning adaptive engine; the "engine" is the practice loop you configure through filters, modes and repeats, plus the analytics that describe it. Verify the current PLAB 1 question count and price on the product page; its MRCP product, for calibration, lists 5,100+ questions at £35 for four months, and the PLAB offer follows the same low-cost pattern. At this price the value is real; this audit is about reading the dashboard honestly, not a reason to avoid the bank.
The exam behind the dashboard
PLAB 1 is 180 single-best-answer questions in three hours (GMC): a short scenario, a question, five options, testing knowledge equivalent to a UK doctor entering the second Foundation year, now aligned to the GMC's Medical Licensing Assessment content map. The consequence for a Q-bank user is that PLAB 1 samples from a defined, published universe of areas of clinical practice, presentations and conditions — so your preparation question is "how much of the mapped universe have I met, in UK context?" not "is my percentage good?"
What each dashboard metric actually measures
First-attempt accuracy on unseen items is the only exam-shaped number, because exam day is one attempt on unseen material. Repeat accuracy rises with familiarity whether or not knowledge grows; it is a review-process metric, never a readiness metric. The peer percentile compares you with a self-selected population of PassMedicine users at unknown stages of preparation — motivating, occasionally, but not a pass forecast, and especially noisy for PLAB where the candidate base spans very different baselines and timelines. Coverage counts attempts, the raw material for the blueprint audit below. Time-per-item catches the failure mode accuracy hides: knowing the medicine at a pace the paper does not allow.
Selection bias: the dashboard measures your choices
Every filter you set biases every statistic you see. Practising your weakest systems deflates your average; drifting to comfortable territory inflates it; repeating errors inflates repeat accuracy while predicting nothing. A percentage generated under self-chosen conditions is not comparable with a mixed, unseen, timed block — and only the latter behaves like PLAB 1. This is the standing argument of Your Q-Bank Percentage Is Not Your Exam Score, and the MLA-aligned blueprint makes it concrete: an inflated average over a narrow slice of the map is the commonest false comfort in PLAB preparation.
The content-map audit — with a jurisdiction lens
Fortnightly, set your attempted-question distribution against the map rather than the app. Three checks. Breadth: which areas of clinical practice have you barely touched? Mental health, child health and the under-revised specialties reliably surface. Professional content: ethics, consent, safeguarding, prescribing safety and GMC good-practice framing carry real weight in an MLA-aligned exam and are exactly what specialty-filtered clinical practice under-samples. And — decisive for IMGs — jurisdiction: track, as an explicit review category, how often your instinctive answer was a home-country default rather than the UK first-line choice. That last check is usually a larger source of marginal marks than any additional clinical volume.
What a credible readiness signal requires
All five conditions: unseen questions, exam-pace timing (about one minute per item), mixed composition across the map, no mid-block look-ups, and a sample of at least 100 questions over multiple sittings before a percentage means anything. Anything else — filtered blocks, repeated items, untimed browsing — is learning activity, valuable but unmeasurable as readiness.
When to override the selector
Force the map's neglected corners on a rota, because low-volume domains generate few questions in a self-directed feed. Force professional-content and prescribing-safety blocks weekly. Force UK-context review whenever a management answer surprises you. And force full random timed blocks weekly — the closest a bank gets to the exam's indifference to your preferences. Comfort is a selection algorithm too, optimising the wrong objective.
A worked dashboard example
Eight weeks from PLAB 1, suppose: overall 67%; medicine and surgery strong and heavily practised; psychiatry 55% over 70 attempts; obstetrics/gynaecology 58% over 80; ethics/consent 15 attempts; prescribing safety thin; timed pace 78 seconds per item. Translated: psychiatry and O&G take the largest quotas; ethics/consent and prescribing safety get scheduled properly rather than incidentally; pace needs three timed blocks to reach the one-minute budget; and a jurisdiction review category is opened for the management misses that were home-country defaults. No overall pass prediction appears — map-aligned quotas are the entire output.
A seven-day pattern for international graduates
Monday: 50 PassMedicine questions across two flagged weak areas. Tuesday: 30 questions plus UK-convention review — NICE-shaped sequences, UK prescribing safety, safeguarding thresholds. Wednesday: a timed, unseen 50-question mixed block in iatroX's free PLAB 1 bank, whose adaptive selection probes related weaknesses across the map. Thursday: light error review. Friday: 40 PassMedicine questions on professional and low-volume content, timed. Saturday: a full timed simulation, alternating source weekly; same-day review by error type. Sunday: rest. PassMedicine does volume and explanations; iatroX does unseen adaptive measurement and cited UK-context verification.
A worked dashboard example
Eight weeks from PLAB 1, suppose PassMedicine shows: overall 67%; medicine and surgery strong and heavily practised; psychiatry 55% over 70 attempts; obstetrics and gynaecology 58% over 80; ethics and consent 15 attempts; prescribing safety thin; timed pace 78 seconds per item. A candidate reading "67% and rising" keeps drilling the comfortable systems. This audit reads it as four concrete jobs. Psychiatry and obstetrics take next week's largest quotas, floors set. Ethics, consent and prescribing safety — the professional content an MLA-aligned paper samples and a clinical feed starves — get scheduled sessions rather than incidental exposure. Pace gets three timed blocks aimed at the one-minute budget. And a jurisdiction-review category is opened for the management misses that turn out to be home-country defaults. No overall pass prediction appears, because the 67% was concealing the professional-content and jurisdiction liabilities most likely to decide a borderline result.
Why the MLA content map changes the PLAB question
It is worth being explicit about what alignment to the GMC content map does to PLAB preparation. Before alignment, "have I covered enough?" was unanswerable — the syllabus was implicit. Now the assessable universe of areas, presentations and conditions is published, so coverage is a checkable fact rather than a feeling, and the useful preparation question shifts from "is my percentage good?" to "how much of the mapped universe have I met, in UK context?" Most candidates waste that gift by continuing to revise against instinct instead of against the list. The discipline the map rewards is unglamorous and decisive: periodically set your attempted distribution against the published areas, find the ones the self-directed feed left thin, and force them. For an IMG, the map also quietly reframes the whole exam — it is not testing whether you know medicine, which you do, but whether you apply it the UK way, which the map makes explicit and auditable.
Continue, supplement, switch or stop
Continue while unseen mixed performance climbs and the map audit levels out. Supplement when bank numbers rise but unseen performance stalls — recognition, not learning. Switch only for a named, measurable gap (our PLAB 1 comparison helps); novelty is not a gap. Stop accumulating volume in the final fortnight once coverage, stability and pacing hold.
The bottom line for international graduates
The honest one-line verdict on PassMedicine for PLAB 1: an inexpensive, high-volume core bank whose dashboard measures your practice, not your readiness — the same story as its other exams, with an IMG-specific twist. The twist is jurisdiction. The MLA-aligned paper rewards the UK way of doing things, and PassMedicine's self-directed loop will happily let you drill the medicine you already know while leaving the UK-context and professional content thin. So the two overrides that matter most are a content-map audit — because coverage is now a checkable fact, not a feeling — and a standing jurisdiction-review category for the management misses that turn out to be home-country defaults. Neither shows up on the dashboard; both are where borderline PLAB results are decided. Buy PassMedicine for its volume and price, read its numbers as practice data, and let an unseen source and a citation-first UK reference carry the two jobs the dashboard cannot: measuring transfer and calibrating jurisdiction.
Frequently asked questions
Is PassMedicine enough for PLAB 1 on its own? It can supply the bulk of practice volume affordably, but it cannot measure your coverage against the GMC content map or your performance on unseen timed material, so pair it with a map audit, a jurisdiction-review habit and an independent source of unseen mixed blocks.
Which PLAB 1 component does PassMedicine not reproduce well? The map's enforced breadth — professional, ethical and prescribing-safety content and the low-volume areas — and the exam's unseen, timed, UK-contextual delivery; specialty-filtered practice systematically under-rehearses both.
How many PassMedicine questions should I complete per day for PLAB 1? Composition beats volume: 40–60 map-directed questions on study days is ample, with two timed unseen mixed blocks protected weekly and a standing UK-context review category for IMGs.
When should I stop using PassMedicine and move to mixed mocks? When your map audit shows every area attempted above your floor, first-attempt accuracy has held for two weeks and pacing fits the paper's budget — the final two to three weeks, given to timed simulation.
How should I combine PassMedicine with iatroX without duplicating practice? PassMedicine for chosen-area drilling; iatroX (free for PLAB 1) for unseen adaptive blocks that measure transfer and cited UK-guideline verification for the jurisdiction gaps IMGs most need to close.
