In-Depth Analysis

Overview

BMJ OnExamination has been a fixture in UK postgraduate exam prep for over two decades. Its editorial authority (questions written under BMJ governance) and coverage of major Royal College exams (MRCP, MRCGP AKT, MRCEM) make it a trusted brand.

iatroX is a newer, AI-integrated platform that offers free access to major UK exam Q-banks and affordable specialist diploma coverage (£29/month or £99/year for all niche diplomas). Its differentiator is the integrated learning loop: Quiz → Ask iatroX (guideline Q&A) → Brainstorm (case simulation) → CPD logging.

When To Use Each

  • Use BMJ OnExamination when: You specifically value BMJ editorial authority, want peer benchmarking data, and are preparing for a single high-stakes exam (e.g., MRCP Part 1) where you want a long-established, trusted bank.
  • Use iatroX when: You want to prepare for multiple exams without multiple subscriptions, need access to underserved niche diploma banks (DGM, DipIMC, DTM&H, DFSRH), or want to understand the guidelines behind your mistakes through AI-powered Q&A.

Key Differences

Pricing Model

BMJ OnExamination charges per exam module. If you are preparing for MRCP Part 1 and MRCGP AKT and DRCOG, that is three separate subscriptions. iatroX offers free access to the major exams and bundles all specialist diplomas into a single subscription.

Niche Diploma Coverage

This is where the gap is widest. BMJ OnExamination does not offer dedicated banks for DGM, DipIMC, DTM&H, or DFSRH. Its FFICM content has been reported by candidates to overlap significantly with FRCA material. iatroX has purpose-built banks for all six specialist diplomas, each mapped to the relevant exam blueprint.

Learning Approach

BMJ OnExamination is a traditional Q-bank: answer questions, read explanations, track performance. iatroX adds an AI layer: when you get a question wrong, you can immediately ask "Why is this the guideline?" and receive a cited answer from NICE/CKS/BNF, then practise a simulated case on the same topic.
