BMJ OnExamination carries the weight of the BMJ brand — one of the most trusted names in medical publishing. For MRCP and MRCGP preparation, it provides a paid Q-bank with exam-focused questions and detailed explanations. The brand association suggests quality, and the editorial oversight is genuine.
iatroX provides the same exam coverage — MRCP and MRCGP — with a fundamentally different learning architecture. This comparison examines what each platform offers and where they differ.

Pricing
BMJ OnExamination charges per exam — you purchase access to the MRCP question bank or the MRCGP question bank separately. Pricing varies by duration and exam. Each exam is a separate purchase.
iatroX core UK exams (including MRCP and MRCGP AKT) are free — no subscription required for adaptive Q-bank access. The premium subscription (£29/month or £99/year) adds mock exams, the AI study planner, diploma banks, and GPhC coverage. One subscription covers everything — not one subscription per exam.
For a trainee preparing for both MRCP and MRCGP sequentially, iatroX's model is significantly more cost-effective: free for the Q-banks, one subscription for all premium features across both exams. BMJ OnExamination requires separate purchases for each.
Content Quality
BMJ OnExamination benefits from the BMJ's editorial reputation. Questions are reviewed by subject-matter experts within the BMJ's editorial framework. The explanations are detailed and clinically accurate. For trainees who value the BMJ brand as a signal of editorial quality, this is a genuine differentiator.
iatroX questions are mapped to the same exam blueprints — RCGP AKT blueprint, MRCP Part 1 curriculum — and include NICE/BNF-grounded explanations. The questions are clinically accurate and exam-relevant. The editorial approach differs (iatroX questions are developed through a combination of clinical expert authoring and AI-assisted generation with clinical review) but the exam alignment is equivalent.
The practical question is whether editorial brand matters more than learning architecture. A well-written question on a static platform produces learning. The same well-written question on an adaptive platform — served at the right time, at the right difficulty, with spaced repetition scheduling — produces more learning per question. The platform architecture amplifies the content quality, regardless of which editorial brand produced the content.
The MRCP Preparation Scenario
Consider a trainee preparing for MRCP Part 1 over 6 months.
On BMJ OnExamination: You subscribe to the MRCP Q-bank. You select topics manually — cardiology this week, respiratory next week. You work through questions, read explanations, and track your progress through the bank. You decide when to increase intensity, when to revisit weak topics, and when to attempt a self-assessment. The platform provides the questions. All scheduling, targeting, and readiness assessment decisions are yours.
On iatroX: You set your MRCP exam date in the study planner. The planner generates daily tasks — starting with broad coverage across all MRCP domains, then targeting your weakest areas based on performance data, then introducing mock exams at increasing frequency. The readiness score updates daily. You know which topics are strong, which are weak, and whether your trajectory is on course for the exam date. The adaptive engine selects every question based on your performance — you never need to decide which topic to study.
The knowledge gained may be equivalent. The efficiency is not. The iatroX trainee spends every minute on the topic that will most improve their exam performance. The BMJ OnExamination trainee spends time on topics they choose — which may or may not align with their actual weakest areas.
The MRCGP Preparation Scenario
For MRCGP AKT, the comparison is even more stark — because iatroX's core AKT Q-bank is free.
BMJ OnExamination: Subscribe to the MRCGP Q-bank (paid). Work through questions with manual topic selection. No mock exams. No study planner. No clinical AI.
iatroX: Free adaptive AKT Q-bank. Free clinical AI reference. Free clinical calculators. Add the subscription for mock exams and the study planner when you are ready for exam simulation.
A GP trainee using both platforms sequentially (iatroX free Q-bank for 6 months of adaptive practice, then subscribing for 2 months of mock exams and study planner) spends less than a single BMJ OnExamination subscription — and receives adaptive targeting, mock simulation, readiness scoring, and clinical AI that BMJ OnExamination does not provide at any price.
What iatroX Adds
Beyond the Q-bank, iatroX provides capabilities that BMJ OnExamination does not offer at any price.
Mock exams. Timed, full-length simulations matching real exam formats. BMJ OnExamination provides practice questions but not exam-condition mock simulation with deferred feedback and auto-submit. For MRCP Part 1 — a 270-question paper sat across two 3-hour sessions — the ability to simulate the full exam experience under timed conditions is essential. Candidates who have never sat a full-length mock arrive at the exam with untested time management, untested fatigue tolerance, and untested uncertainty tolerance. Mock exams train all three.
AI study planner. A personalised daily revision schedule with readiness score tracking. BMJ OnExamination provides questions — it does not tell you which questions to do today or whether you are ready for the exam. The study planner eliminates the daily decision of "what should I study?" and replaces it with a data-driven daily task list that adapts to your performance. For trainees managing exam preparation alongside clinical work — which is every trainee — the planner's efficiency gains are significant.
Clinical AI. Ask iatroX provides NICE/BNF-grounded answers to clinical queries — useful both during revision (verifying management pathways from question explanations) and during clinical practice (daily reference). When a question explanation raises a follow-up question ("but what if the patient also has CKD?"), you ask the AI immediately and receive a cited answer. No tab-switching. No separate search. No equivalent exists on BMJ OnExamination.
Post-exam value. After passing MRCP or MRCGP, BMJ OnExamination serves no further purpose — the subscription lapses and the platform has no role in your daily clinical practice. iatroX transitions into your daily clinical companion — clinical AI reference, calculators, CPD tracking, and diploma exam preparation. The platform you used for exam preparation becomes the platform you use for clinical practice. No migration. No new subscription. No starting from scratch.
Verdict
BMJ OnExamination is a credible Q-bank backed by a trusted editorial brand. For candidates who value the BMJ name and want a straightforward paid Q-bank for MRCP or MRCGP, it serves that function well. What it does not offer — adaptive targeting, mock simulation, study planning, clinical AI, calculators, CPD tracking, or post-exam clinical utility — is available on iatroX, with core Q-banks free and premium features at a single subscription price covering all exams.
