SpecialityMCQs vs iatroX: what free covers, and what it doesn't

quiz iatroX, per iatroX's own site (2 September 2026), is entirely free with no question limit for MRCP Part 1 and 2, MRCGP AKT, MSRA, PLAB 1, UKMLA AKT, MRCEM, PSA and PANE, and describes itself as adaptive exam preparation. For MSRA and MRCEM specifically — the two exam families SpecialityMCQs and iatroX both cover — there is no cost reason to look elsewhere before trying it first.

SpecialityMCQs covers seven exam families: MRCS Part A, MRCOG Part 1 and 2, MRCPCH FOP and TAS, MRCPsych Paper A and B, MRCEM Primary and SBA, Final FRCR Part A, and MSRA. Of those, MRCOG, MRCPsych, Final FRCR Part A, MRCS Part A and MRCPCH do not appear on quiz iatroX's published free-exam list. For those five, the question of free versus paid doesn't really arise, because the free option isn't on the table for them. MSRA and MRCEM are the two families where both are genuinely live options.

For MSRA specifically, SpecialityMCQs's Professional Dilemmas practice is marked on how close a ranking or select-three answer is to the reference answer — the same closeness-based marking NHS England itself uses — rather than a flat right-or-wrong. Sessions across both MSRA and MRCEM are weighted to each exam's published blueprint and tilted toward whichever subject is currently costing the most marks, with anything missed returning on a spacing schedule. Every answer, on every exam, names the guideline or reference it rests on.

None of that is free: a SpecialityMCQs plan covers every exam family in one login, for one price, including the five that quiz iatroX's free list doesn't reach. Content is written and fact-checked with AI assistance against named sources, not individually signed off by a physician.
