The GPhC question bank market is crowded. At least six paid platforms and one major free option all claim comprehensive coverage and high pass rates. They all have questions. They all cover the CRA framework. On the surface, they look interchangeable.
They are not. The platforms are built on fundamentally different models — static versus adaptive, volume versus targeting, text-based versus BNF-integrated. The one you choose has a direct impact on how efficiently you prepare and, ultimately, whether you pass.
This review compares each platform honestly across the dimensions that matter: question quality, adaptive learning, BNF/NICE integration, calculations coverage, mobile access, and value. iatroX is one of the platforms reviewed — we are transparent about that — but the facts are presented for you to judge.

PassMedicine Pharmacy — The Free Option
PassMedicine extends its established medical revision platform into pharmacy with a free question bank covering GPhC framework topics. The interface is familiar to trainees who used PassMedicine during their MPharm years.
Strengths: Free — the only major free option. Familiar interface. Covers core therapeutic topics.
Limitations: Static bank — questions appear in rotation regardless of your performance profile. Not updated to the 2026 CRA framework changes. No adaptive engine. Web-only (no native mobile app). No BNF integration. Explanations can be brief.
Who it suits: Trainees on a tight budget who need baseline question practice and are comfortable self-directing their revision without performance analytics.
Who should look elsewhere: Trainees who want personalised targeting, BNF-anchored explanations, or mobile-first revision.
PreRegExamPrep.com — The Volume Option
PreRegExamPrep is a dedicated GPhC revision platform with over 2,000 questions across SBA, EMQ, and calculation formats. It has the largest static question bank in the market, with detailed explanations and performance analytics.
Strengths: Largest static question bank. Good explanation quality. Covers all three question formats. Performance analytics.
Limitations: Static rotation — no adaptive engine. Questions not linked to live BNF/NICE guidance. Web-only — no mobile app. From £30/month.
Who it suits: Trainees who want maximum question volume and are comfortable self-directing their revision across topics.
Who should look elsewhere: Trainees who need personalised targeting, mobile access, or guideline-grounded explanations.
ONtrack Pharmacy — The UK Specialist
ONtrack provides thousands of questions in authentic GPhC exam style — SBAs, EMQs, and calculations. The platform has a UK pharmacy community feel with pharmacy news integration.
Strengths: UK-focused. Question format closely matches the real exam. Active user community.
Limitations: Static bank. No adaptive engine. No BNF integration. Web-only. Analytics are basic.
Who it suits: Trainees who want platform-authentic question practice and value a UK pharmacy community.
Who should look elsewhere: Trainees who want adaptive personalisation or mobile access.
Coditioning — The Strategy-Focused Option
Coditioning provides over 1,000 questions alongside strong exam strategy content. The accompanying guidance on the CRA framework, exam technique, and calculation approaches is genuinely useful.
Strengths: Strong exam strategy and technique content. Good calculation drills. Clear framework guidance.
Limitations: Moderate question volume. Static bank. No adaptive engine. No BNF integration.
Who it suits: Trainees who benefit from exam technique coaching alongside question practice — particularly those who are unsure how to approach the CRA strategically.
Who should look elsewhere: Trainees already confident on exam technique who need raw adaptive question practice.
iatroX — The Adaptive Option (iatrox.com/boards)
What makes iatroX fundamentally different is the adaptive engine — built on cognitive science principles (spaced repetition, retrieval practice, mastery learning) rather than static question rotation.
How the adaptive engine works for GPhC: After each question, the engine updates your proficiency profile across all CRA content areas. It selects the next question to maximally challenge your weakest area. Difficulty scales as you improve — you never waste time on topics you have already mastered. The result: the same revision time produces more targeted improvement than a static bank.
BNF and NICE integration. Every Part 2 explanation references the relevant BNF section or NICE guideline. You are revising from the same sources the exam tests against. When guidance updates, explanations update. This is not static authored text — it is guideline-grounded, citation-linked content.
Part 1 calculations adaptive. Calculation types are tracked separately. If you are strong on IV rates but weak on displacement values, the engine concentrates there. Difficulty scales within each calculation type as your accuracy and speed improve.
Performance dashboard. Topic-level proficiency map across all CRA therapeutic areas and content domains. Shows you exactly where exam risk lies — before exam day, not after.
Mobile app. iOS and Android — the only GPhC revision platform with a native mobile app. Revise in the dispensary, on the bus, between consultations during your foundation year placements.
MHRA-registered platform. Clinical governance standard applied to content — unique in the pharmacy revision market.
Who it suits: Trainees who want personalised, adaptive revision targeting their actual gaps. Trainees who revise on mobile. Trainees who want BNF-grounded explanations. Trainees who want a performance dashboard showing exactly which therapeutic areas or calculation types need work.
Who should combine it with something else: Trainees who want maximum raw question volume can pair iatroX (adaptive targeting) with PassMedicine (free supplementary volume) or PreRegExamPrep (largest static bank) — the combination covers both precision and breadth.

The Recommended Combination Strategy
For most candidates: iatroX (adaptive targeting + BNF integration) + PassMedicine (free supplementary volume) = the highest-value revision stack. You get personalised precision from iatroX and additional question exposure from PassMedicine, at minimal combined cost.
For candidates who want maximum coverage: iatroX + PreRegExamPrep covers both adaptive intelligence and raw question volume.
The logic: No single static platform knows what YOU do not know. iatroX does. That is the fundamental difference.
The GPhC's Own Free Resources — Do Not Overlook These
Regardless of which Q-bank you choose, use these: official example questions on the Surpass platform (essential for format familiarity), the CRA framework document with indicative assessment topics (your revision blueprint), and the Board of Assessors feedback documents published after each sitting (shows what candidates got wrong — use these to shape your revision priorities).
None of the paid platforms replicate these. Use them alongside whichever Q-bank you choose.
Every platform reviewed here gives you question practice. What distinguishes iatroX is personalisation — it makes your revision efficient, not just voluminous. Start the iatroX GPhC adaptive bank today.
