This is the implementation companion to our Medibuddy PLAB 1 analytics audit — read that for what Topic Mastery means; read this for the week-by-week routine. The job is narrow: use Medibuddy's adaptive engine for what it does well (targeting weak topics), override it where it under-samples the GMC content map, and switch to timed simulation on objective criteria — with a standing jurisdiction category for the international graduate's real bottleneck.
What you are working with
Medibuddy is an adaptive, low-cost bank with a Topic Mastery engine, spaced-repetition re-tests, and adaptive and traditional modes; MSRA pricing runs £30–£60 and PLAB follows the same pattern (verify counts and price on the product page). The exam is 180 single-best-answer questions in three hours (GMC), aligned to the MLA content map.
Week structure at a glance
| Phase | Weeks (typical 8–10 week run) | Primary mode | Exit trigger |
|---|---|---|---|
| Baseline | 1 | Traditional mode, map-stratified sample | ~100 items logged across areas |
| First pass | 2–6 | Adaptive mode + map-floor overrides | Every area above its floor |
| Consolidation | 7–8 | Timed mixed blocks + jurisdiction fixes | First-attempt accuracy stable |
| Simulation | 9–10 | Full mixed timed mocks | Pacing on target; go/no-go |
Baseline before you trust the engine
Spend week one in traditional mode on a map-stratified unseen sample, before the adaptive engine personalises the feed. Because the MLA content universe is published, this gives you a checkable reference distribution against which to judge whether the engine later leaves map gaps.
Follow the algorithm — then override it
Let the engine target your low-Mastery subjects in the first-pass phase. But override it on coverage, because it optimises for your improvement curve, not the map's distribution. Set map-area floors and force the areas the feed under-samples — professional content, presentation-level reasoning, low-volume specialties. And add the IMG override: a standing jurisdiction category, forcing UK-context review whenever a management answer surprises you.
Error taxonomy with a jurisdiction category
Sort each miss into the six standard types plus jurisdiction. Let spaced repetition handle re-tests of genuine knowledge gaps, but prove closure with fresh transfer questions rather than repeats, and route jurisdiction misses to a UK-context fix and a citation-first check.
The mixed-block switch and exit criteria
Move from adaptive practice to timed random blocks when every map-area floor (including professional and UK-context content) is met, first-attempt accuracy on unseen material has held for two weeks, and pace is within the one-minute budget. Then invert to mostly-mixed. Exit when coverage, stability, pacing and a settled jurisdiction log all hold — not when the bank is exhausted or the Mastery bars are green.
A worked example
Suppose after three weeks the engine has driven your weak clinical subjects up, and the feed still concentrates there. Following it is correct for those subjects — but your map audit shows professional content (ethics, consent, prescribing safety) attempted lightly and never prioritised by the engine, and a jurisdiction log full of home-country-default misses. This is the override moment: force professional-content blocks in traditional mode, and schedule UK-context review specifically for the jurisdiction gaps. The engine owns depth on weak subjects; you own map breadth and jurisdiction calibration.
A seven-day pattern for international graduates
Monday: 40 Medibuddy questions in adaptive mode, misses taxonomised. Tuesday: 30 questions plus UK-convention review for jurisdiction gaps. Wednesday: a timed, unseen 50-question mixed block in iatroX's free PLAB 1 bank — your uncontaminated readiness signal. Thursday: light review; jurisdiction log updated. Friday: 40 Medibuddy questions in traditional mode on professional and low-volume content, timed. Saturday: a full timed simulation, alternating source weekly; same-day review. Sunday: rest. Medibuddy drills adaptively; iatroX measures on unseen items and grounds UK-context answers with citations.
Continue, supplement, switch or stop
Continue while floors fill and unseen performance climbs. Supplement with unseen transfer blocks whenever repeat accuracy or Mastery outpaces first-attempt accuracy. Switch only for a measurable gap, never for novelty. Stop drilling and commit to simulation once the exit criteria hold — usually the final fortnight.
Frequently asked questions
Is Medibuddy enough for PLAB 1 on its own? Its adaptive engine can carry the bulk of practice, but the workflow still needs unseen transfer questions, a map audit and deliberate UK-context work, because a single adaptive bank cannot both drill you and independently measure or calibrate you.
Which PLAB 1 component does Medibuddy not reproduce well? The map's enforced breadth under unseen timed conditions — professional and UK-context content — which the adaptive feed under-samples relative to the medicine you already know.
How many Medibuddy questions should I complete per day for PLAB 1? 40–60 on study days by floor deficits rather than the feed's preference, with two timed mixed blocks weekly and a standing jurisdiction category.
When should I stop using Medibuddy and move to mixed mocks? When every map area is above its floor, first-attempt accuracy is stable and pacing fits the budget — invert to mostly-mixed, typically the final two to three weeks.
How should I combine Medibuddy with iatroX without duplicating practice? Medibuddy for adaptive floored drilling; iatroX (free for PLAB 1) for unseen transfer measurement and cited UK-guideline verification of the jurisdiction gaps that decide IMG results.
A worked override example
Suppose after three weeks the adaptive engine has driven your weak clinical subjects up nicely, and the feed still concentrates there. Following it is correct for those subjects — but your map audit shows what the Mastery view hides: professional content (ethics, consent, prescribing safety) attempted lightly and never prioritised by the engine, and a jurisdiction log full of home-country-default misses. This is the override moment. In traditional mode you force professional-content blocks, and you schedule UK-context review specifically for the jurisdiction gaps the log keeps flagging. The engine owns depth on your weak clinical subjects; you own map breadth and jurisdiction calibration — the two things an adaptive PLAB feed will never guard for you, and the two that most often decide an IMG's result.
The bottom line for international graduates
The honest one-line verdict on Medibuddy for PLAB 1, in workflow terms: use the adaptive engine for depth on weak subjects, override it for the content-map breadth and UK-context content it under-samples, and switch to timed simulation on objective criteria rather than a green dashboard. Set map-area floors, preserve an unseen signal outside the feed, and run a standing jurisdiction category for the management misses that are home-country defaults. Read Topic Mastery as a compass and not a finish line, because a subject turns green on the items the algorithm chose, not the ones the exam will ask. Do those and Medibuddy is a sensible, affordable core for PLAB; take its Mastery bars as readiness and skip the jurisdiction work, and its reassuring dashboard is exactly the false comfort that sinks well-prepared-feeling international graduates on the map's neglected corners.
A worked dashboard example
Eight weeks from PLAB 1, suppose Medibuddy shows: overall 66%; Topic Mastery high in medicine and surgery, low in psychiatry and obstetrics; the adaptive feed weighted to your weak clinical topics; ethics and consent barely attempted; prescribing safety thin; pace 80 seconds per item. A candidate reading "66% and improving" keeps going. The workflow produces a specific fortnight instead: psychiatry and obstetrics take the largest quotas; ethics, consent and prescribing safety get scheduled sessions rather than incidental exposure; three timed blocks bring pace toward the one-minute budget; the deflated recent accuracy is read correctly as the engine doing its job on your weak areas, not a decline; and a jurisdiction category opens for the home-country-default misses. Next week is map-aligned quotas, not a pass prediction — because the 66% was concealing the professional-content, pace and jurisdiction liabilities most likely to decide a borderline result.
One practical note on cost: iatroX's PLAB 1 bank is free, so using it as your preserved unseen-measurement source alongside Medibuddy adds nothing to your outlay — the two-source design that keeps your readiness signal honest, and the citation-first checks that close your jurisdiction gaps, are available whatever your budget, which for a relocating international graduate managing the considerable costs of moving to and settling in the UK is genuinely worth knowing.
