This plan is for renal medicine trainees — typically ST4 and above — sitting the European Specialty Examination in Nephrology (ESENeph) who use BMJ OnExamination and want a structured first-pass, review and exit sequence that never spends its whole question pool. It addresses the written, two-paper knowledge exam only. The principal limitation to name up front: BMJ OnExamination does not advertise a proprietary adaptive-difficulty algorithm, so "adaptive" here means you reading your own domain data and reallocating time — and it means deliberately keeping some questions unseen so your final calibration is real.

Figures are vendor-reported and captured on 20 July 2026; confirm the current count and price on the product page. Note the honest distinction: "Personalised Daily Question" and revision prompts are delivery features, not evidence of an algorithm that raises or lowers item difficulty to your ability. That is fine — you do not need one — but it means the adaptation in this workflow is deliberate and manual, and it is the reason preserving an unseen pool matters so much.
The ESENeph exam you are actually preparing for
ESENeph is the SCE for renal medicine, delivered jointly by the Federation of the Royal Colleges of Physicians of the UK, the European Renal Association (ERA), the European Section and Board of Nephrology (UEMS Renal) and the UK Kidney Association. Format: two papers of 100 best-of-five questions each (200 total), three hours per paper, one mark per correct answer, no negative marking, computer-based via Surpass at a test centre. UK trainees map to the JRCPTB Specialty Training Curriculum for Renal Medicine, and items are selected against the published SCE in Nephrology blueprint.
Two facts shape the plan. No negative marking means you answer every item without exception. And the blueprint runs from the high-frequency core — acute kidney injury and electrolytes, chronic kidney disease, glomerulonephritis, transplantation and dialysis — out to lower-volume territory that revision routinely under-serves: inherited and rarer diseases, renal bone–mineral disease, the kidney in pregnancy, peritoneal dialysis prescription and its complications, and pharmacology in renal impairment. The official blueprint and any released example questions are your calibration standard; vendor item counts are third-party claims.
Baseline week: measure before you personalise
Before you accept any "daily question" rhythm or difficulty filter, run a small, blueprint-stratified unseen sample under timed conditions — roughly 60 to 80 questions spread across every domain, including the low-volume ones. Record first-attempt accuracy per domain outside the platform. This baseline is the map you will audit against, and it stops a comfortable overall number from concealing a thin patch in, say, inherited disease or PD-related peritonitis. The nephrology curriculum is unusually front-loaded with high-volume topics, which makes the overall percentage especially good at hiding the tail.
First pass: set domain floors the overall score cannot hide
Commit to a minimum attempted-and-reviewed count per blueprint domain before any topic is allowed to count as covered. Weight the floors so the naturally under-served areas are protected:
| Blueprint area (illustrative) | First-pass floor | Why it slips |
|---|---|---|
| AKI and electrolyte disorders | High volume anyway | Over-served naturally |
| CKD, haematuria, proteinuria | High volume anyway | Familiar, comfortable |
| Glomerulonephritis / TIN | Moderate | Feels "done" quickly |
| Transplantation | Floor it | Immunosuppression detail gets skimmed |
| Dialysis — haemo and peritoneal | Floor it | PD prescription and complications neglected |
| Renal bone–mineral disease, anaemia | Floor it | Low interest, real marks |
| Inherited and rarer diseases | Floor it | Alport, Fabry, atypical HUS slip through |
| Pregnancy and the kidney | Floor it | Small domain, high skip rate |
Tick each domain against its floor and never let the global percentage stand in for coverage — this is a blueprint-coverage matrix in miniature.
An error taxonomy that tells you what to do next
Tag every miss with one of six codes, because each demands a different response:
| Code | Meaning | Fix |
|---|---|---|
| K | Knowledge gap | Short source read, then a fresh transfer item |
| M | Misread stem | Slow the read; no re-study |
| P | Premature closure | Build the differential before answering |
| G | Guideline error | Read the current standard |
| C | Calculation error — e.g. clearance, correction, transplant dosing | Drill the sum |
| T | Time-pressure error | Fix in timed mixed blocks |
Nephrology carries more calculation and interpretation items than most specialties — acid–base, sodium correction rates, clearance and dosing in impairment — so the C code earns its own drills rather than topic re-reading.
Review interval: what to repeat, space, or read
Do not reflexively re-answer a missed item; that trains recognition. A knowledge gap (K) earns a short read now and a new item on the same principle in a few days. A guideline error (G) earns a read of the current standard and a spaced re-test. Misreads (M) and premature closure (P) are process faults — flag and move on. Only calculation errors (C) justify an immediate, repeated drill, because there the mechanic itself is the learning target.
The mixed-block switch: objective criteria
Topic-filtered blocks cue you — an all-transplant block half-answers itself. Switch towards timed, random, mixed blocks when every domain floor is ticked, your unseen first-attempt accuracy has stopped rising, and you are within about four weeks of the exam. From then, most practice should be mixed and timed at roughly 1.8 minutes per item, because that is the condition the two real papers impose.
Exit criteria: preserve the unseen pool
The distinctive move in this plan is that you finish with questions left unused. Ring-fence a slice of the bank — the curated Mock Tests plus a reserved tranche you never touch in first-pass study — as your unseen calibration pool. You are ready when: every domain floor is met; your first-attempt accuracy on that untouched pool is stable and adequate; your pacing sits comfortably inside a full 3-hour, 100-question paper with review time; spaced re-tests hold; and your performance matches the Federation blueprint weighting rather than only the vendor's mock. Bank completion is explicitly not on that list.
A seven-day plan for a busy trainee
BMJ OnExamination does the coverage and content job; iatroX supplies unseen transfer questions so measurement stays clean. No proprietary-algorithm claims — this is a manual loop you run yourself.
| Day | BMJ OnExamination (one job) | iatroX (unseen measurement) |
|---|---|---|
| Mon | 25 items across two neglected domains; tag misses | — |
| Tue | Source read on Monday's K/G misses | 10 fresh items on the same principles, timed |
| Wed | 25 items; a calculation-heavy set (Na, clearance) | — |
| Thu | Clear flagged M/P process faults | 10 fresh mixed items, timed |
| Fri | 25 items; update the coverage matrix | — |
| Sat | One curated Mock Test, timed | — |
| Sun | Spaced re-test of the week's misses | 20-item unseen block; log first-attempt % |
If your BMJ accuracy climbs while the Sunday unseen number stays flat, you are learning the bank rather than nephrology — widen coverage and lean into transfer practice at once.
Three mistakes this plan is designed to stop
Spending the entire question pool in first-pass study, leaving nothing clean to calibrate against. Letting a high overall percentage — inflated by the high-volume core — disguise thin low-volume domains. And re-reading topics after every miss when many misses are misreads, process faults or calculation slips that need a different fix entirely.
Decision checklist: continue, supplement, switch or stop
- Continue BMJ OnExamination if floors are filling and unseen accuracy is trending up.
- Supplement with an unseen source if seen-item accuracy is high but unseen accuracy lags by more than about ten points.
- Switch emphasis to timed mixed mocks once floors are met and unseen accuracy plateaus.
- Stop collecting banks out of anxiety; identical blind spots in a second bank do not close a coverage gap.
Where iatroX fits (and where it does not)
Be plain: iatroX is not a nephrology-specific SCE bank. It is a cross-specialty, MRCP-level knowledge and unseen-MCQ measurement layer with spaced retrieval. For ESENeph it does one job well — supplying fresh, unseen questions so you can confirm transfer rather than re-testing memorised items. Let BMJ OnExamination be the content engine and iatroX be the neutral yardstick, which is exactly the split described in the two-Q-bank rule. It does not reproduce the ESENeph blueprint and does not replace a dedicated nephrology bank.
Bottom line: BMJ OnExamination is a workable content and coverage engine for ESENeph, and its personalised-delivery features are a convenience, not an algorithm to lean on. The plan that beats grinding it flat is a manual one: domain floors, an error taxonomy that respects nephrology's calculation load, and a preserved unseen pool that lets your final calibration mean something.
Frequently asked questions
Is BMJ OnExamination enough for ESENeph on its own? A single well-worked bank plus the Federation blueprint can be enough for a well-prepared trainee, but only if you cover the whole blueprint and keep an uncontaminated way to measure yourself. The bank supplies breadth and explanations; it does not guarantee coverage of the low-volume tail or provide an unseen final check. With domain floors and a preserved pool it can suffice; as an item-memorisation run it will not.
Which ESENeph component does BMJ OnExamination not reproduce well? ESENeph has no OSCE or viva — it is entirely written best-of-five — so there is no clinical component for a bank to miss. The real gap is a condition, not a format: once you have reviewed the items, the bank cannot easily give you a large, blueprint-stratified pool of never-seen questions under timed random conditions, which is what the two real papers test and why you ring-fence an unseen pool.
How many BMJ OnExamination questions should I complete per day for ESENeph? There is no official quota. A sustainable 20 to 30 reviewed questions a day around clinical work — each miss tagged, each K/G miss read up, transfer tested — beats an occasional 100 left unreviewed. Because nephrology has heavy calculation content, budget some of that daily time for drills rather than raw item volume, and pace yourself against weeks-to-exam rather than a completion figure.
When should I stop using BMJ OnExamination and move to mixed mocks? Move the emphasis to timed mixed mocks once every domain floor is met, your unseen first-attempt accuracy has plateaued, and you are within roughly four weeks of the exam. Before that, filtered blocks build coverage; after it, they mostly cue you to answers and stop resembling the real, mixed, timed papers.
How should I combine BMJ OnExamination with iatroX without duplicating practice? Give each one job and never test the same item twice. BMJ OnExamination is your nephrology content and coverage engine; iatroX is your unseen-measurement layer, where you answer fresh questions on the same principle to confirm transfer. If you catch yourself re-doing seen items to lift a percentage, you have duplicated practice and lost calibration — the reason your Q-bank percentage is not your exam score.
