This workflow is for anaesthetics trainees revising the Final FRCA Written around clinical shifts who want to drive a single-best-answer bank like BMJ OnExamination by the blueprint rather than by whatever the interface serves next. It addresses the MCQ/SBA paper specifically. The principal limitation to name up front: BMJ OnExamination is an SBA bank, so it does not reproduce the Constructed Response Question (CRQ) paper or the Structured Oral Examination — you must build those separately.
What BMJ OnExamination offers for Final FRCA right now
As of 19 July 2026, BMJ OnExamination lists a Final FRCA bank of 800 SBA questions (vendor-reported), mapped to the Final FRCA curriculum and edited by a past examiner. Subscriptions run from about £41.99 for one month to £151.99 for twelve months (vendor-reported); a free trial offers ten questions a day. Functional features include answer explanations with Key Learning Points, a "Select Questions" tool to choose difficulty and recap flagged items, mock tests built around recent exam themes, a group-learning leaderboard, and an offline mobile app. Verify the current count, price and features on onexamination.com before subscribing.
One honest clarification about the word "adaptive": the product page does not describe a proprietary adaptive-difficulty engine. The personalisation here is user-directed — you choose difficulty, filter by topic and recap flagged questions. So the "adaptive" workflow below is one you drive by hand against the blueprint, not an algorithm you delegate to. That is a feature, not a flaw: it keeps you in control of coverage.
Final FRCA Written: the official shape (current until 2027)
The Final FRCA Written currently has two components sat on different days. The CRQ paper contains twelve constructed-response questions in three hours, each marked out of twenty, all to be attempted, with a modified-Angoff pass mark. The MCQ paper contains ninety single best answers in three hours — broadly around forty-five general anaesthesia items, ten perioperative medicine, ten regional, and twenty-five spanning the remaining curriculum — with one mark each and no negative marking. A separate Structured Oral Examination sits elsewhere in the Final FRCA. Crucially, the Royal College of Anaesthetists has FRCA format changes scheduled for 2027, so treat everything here as current-format and verify against the RCoA 2027 changes hub (rcoa.ac.uk) before you plan a diet. A single-best-answer bank speaks to the MCQ paper only.
Because the Final FRCA is prescribing-heavy, note the medicines reference: use the SmPC via the electronic medicines compendium (eMC), read with RCoA and Association of Anaesthetists guidance and NICE — not a generic formulary shorthand.
Baseline week: measure before you personalise
Before you let any interface, filter or leaderboard shape your feed, complete a small blueprint-stratified unseen sample — say 60–90 questions spread deliberately across the curriculum in rough proportion to the paper: a block of general anaesthesia, and smaller fixed blocks of perioperative medicine, regional, pain, intensive care, and the low-volume specialties (obstetric, paediatric, neuro, cardiothoracic). Record first-attempt accuracy per domain. This baseline is the thing a rising overall percentage will later try to hide.
First pass: set domain floors
The failure mode in any large bank is comfortable drift: you answer more of what you are already good at, the overall score climbs, and an untouched low-volume domain sits at zero attempts. Prevent it by setting domain floors — a minimum number of attempted questions per blueprint area before you are allowed to celebrate the headline number. For example, no domain below 40 attempted items and none below your target first-attempt accuracy, however small its share of the paper. Use the "Select Questions" topic filter to service the floors deliberately, not to marinate in your strengths.
Error taxonomy: label every miss
Sort each wrong answer into one of six causes, because the fix differs for each:
- Knowledge gap — you did not know the fact or mechanism.
- Misread stem — you knew it but misread the vignette or the lead-in.
- Premature closure — you locked onto a diagnosis or plan and stopped reading.
- Guideline error — your management was out of date against current UK guidance.
- Calculation error — a dose, flow, dead-space or pharmacokinetic slip.
- Time-pressure error — a mistake that only appears under the clock.
Tally the causes weekly. A bank of knowledge gaps needs reading; a bank of misreads and premature closure needs timed practice and a stem-reading drill, not more content.
Review interval: match the fix to the error
Not every miss deserves an immediate repeat — repeating the same item mostly trains recognition of that item. Instead: a knowledge gap earns a short source read plus a new transfer question on the same concept; a guideline error earns a primary-source check and a spaced review in a few days; a misread or premature-closure error earns timed mixed practice rather than re-reading; a calculation error earns a drilled worked method. Reserve immediate repeats for genuine one-off slips.
Mixed-block switch: when to stop filtering
Topic-filtered practice is for building; mixed random blocks are for testing. Move from filtered to mixed once your domain floors are all met and your per-domain first-attempt accuracy is within a narrow band of your target. The objective criterion: when no single domain is dragging and your errors are increasingly misreads and pacing rather than knowledge, reduce filtered practice and increase full-length, timed, random blocks that mirror the ninety-question paper.
Exit criteria: what "ready" actually means
Bank completion is not readiness. Exit when five things are true: every blueprint domain clears its coverage floor; first-attempt accuracy on unseen items is stable across two or more sittings; you are pacing comfortably at roughly two minutes per SBA; retention holds on spaced re-tests rather than fresh reads; and you have calibrated against the College's own material — RCoA sample questions or a past-paper equivalent — not just the commercial bank. The CRQ paper and SOE need their own preparation and their own exit tests.
Worked example: a seven-day plan
A busy trainee, six weeks out, revising around clinical work. BMJ OnExamination does one job — SBA volume and topic drill — and iatroX supplies unseen transfer measurement. No proprietary-algorithm claims.
- Day 1: Blueprint-stratified baseline (about 75 items) on BMJ OnExamination; log per-domain first-attempt accuracy.
- Day 2: Service the two weakest low-volume domains to their floors using topic filters; error-tag every miss.
- Day 3: Source reads for day-2 knowledge gaps; check any drug fact against the SmPC/eMC.
- Day 4: A 90-question timed mixed block; separate misreads and premature closure from true gaps.
- Day 5: A fresh, unseen timed Final FRCA block in iatroX — no filtering, no assistance — to measure transfer.
- Day 6: Spaced review of the week's guideline and calculation errors; one CRQ plan sketched to keep that muscle alive.
- Day 7: Recompute domain floors and the error tally; set next week's minimums.
Decision checklist: continue, supplement, switch or stop
- Continue if floors are filling and unseen first-attempt accuracy is trending up.
- Supplement with a second, unseen bank if your BMJ score is high but transfer to fresh items lags, or if a low-volume domain is thin in the bank.
- Switch emphasis to CRQ and SOE preparation once the SBA paper is on track — the written mark needs both papers.
- Stop filtered SBA practice inside the final fortnight and move to timed, mixed, unseen blocks plus official-material calibration.
Base each decision on a measurable gap, not on how many questions remain unticked.
Bottom line
BMJ OnExamination is a strong, examiner-edited SBA bank and a reasonable spine for the Final FRCA MCQ paper — provided you drive it by the blueprint, keep domain floors so a rising average cannot mask an untouched low-volume topic, and remember it covers neither the CRQ paper nor the SOE. Use it to build, and reserve a clean, unseen set to measure. With 2027 format changes coming, confirm the current structure before you commit a diet.
FAQ
Is BMJ OnExamination enough for Final FRCA on its own? No, and not because it is weak. It is a single-best-answer bank, so it prepares you for the MCQ paper but not for the CRQ paper's constructed responses or the Structured Oral Examination, each of which needs its own targeted practice. As a spine for the SBA component, combined with the College's own materials and dedicated CRQ and SOE work, it is a strong option; as a complete Final FRCA solution, it is not.
Which Final FRCA component does BMJ OnExamination not reproduce well? The CRQ paper and the SOE. Recognising the best of five options is a different skill from generating a structured, marked-out-of-twenty written answer under time, or from defending a management plan aloud to examiners. Use the bank to consolidate the underlying knowledge, then rehearse CRQ structure against past papers and practise the oral separately.
How many BMJ OnExamination questions should I complete per day for Final FRCA? There is no official number; sustainable pace beats heroics. Many trainees revising around clinical work manage roughly 30–50 questions a day with full review, which matters far more than volume — an unreviewed block teaches little. Prioritise clearing domain floors and error-tagging over a daily total, and protect at least one timed mixed block each week.
When should I stop using BMJ OnExamination and move to mixed mocks? Once every blueprint domain has cleared its coverage floor and your per-domain first-attempt accuracy is stable and near target, filtered single-topic practice yields little. In the final two to three weeks the binding constraints are pacing and stamina across ninety questions in three hours, so shift to full-length, timed, mixed, unseen blocks and official-material calibration.
How should I combine BMJ OnExamination with iatroX without duplicating practice? Give each bank one job. Learn and drill on BMJ OnExamination; reserve iatroX for fresh, unseen, timed blocks that measure whether the learning transferred — and never re-enter a BMJ item into iatroX or vice versa. That separation, set out in the iatroX two-Q-bank rule, keeps calibration honest: one bank to build on, one clean bank to measure on.
