Here is what happens to almost every foundation trainee pharmacist between September and April. You ask the WhatsApp group what to use. Someone says PharmX. Someone says Coditioning. Someone says Focus Pre-Reg. Someone says just use PassMedicine, it is free. By December you have subscriptions to two platforms, a set of downloaded slides you have not opened, and the creeping feeling that you are preparing for the wrong exam with the wrong tools.
The problem is not a lack of resources. The problem is that nobody has explained what each resource actually does well, what each one does poorly, and how they fit together. Every platform's own marketing says it is the complete solution. None of them is. The candidates who score highest figure this out by about week six of revision. This post saves you those six weeks.
Five criteria. Four platforms. One honest assessment.
The Five Criteria That Actually Matter
1. Question volume and format match. The CRA has a specific format: Part 1 is 40 numerical free-entry calculations. Part 2 is 90 SBAs and 15 EMQ sets. A resource that gives you MCQs but not EMQs is only preparing you for part of the paper. A resource with 500 questions and one with 2,000 questions serve different needs at different revision stages.
2. Adaptive vs static. A static bank serves questions in a fixed order or random rotation. An adaptive engine analyses your performance and serves the next question to target your weakest area. The difference sounds marginal. It is not. A candidate who is strong in cardiovascular but weak in endocrine needs more endocrine questions — a static bank cannot provide this.
3. Content currency. NICE guidance, SmPCs and assessment requirements change on different schedules. Ask whether explanations cite a dated source, how updates are detected, and whether clinical content is reviewed continuously or only during periodic editorial releases.
4. App availability. You revise on the bus, in the dispensary during quiet moments, and on your phone at 10pm. A platform that only works on desktop is a platform you will not use consistently. A native mobile app with offline capability changes when and where you can revise.
5. Value. Not just price — what you get per pound. A £200 lifetime licence that covers 70% of what you need is different value from a £99/year subscription that covers 100% of what you need.
PharmX
PharmX has built a large UK trainee-pharmacist community. Its structured slides cover clinical therapeutics, pharmacy law and calculations topic by topic. The systematic teaching and community layer — live sessions, peer support and discussion groups — may be especially valuable to trainees who feel isolated in community placements.
The slides are well-structured. They cover the CRA framework comprehensively. The pricing model (lifetime access) is genuinely good value compared to monthly subscriptions — you pay once and retain access through retakes if needed.
Where PharmX is strong: Knowledge building. If you do not understand the pharmacology of ACE inhibitors or the CD schedule structure, PharmX's slides explain it clearly. The community layer provides motivation and peer accountability. The lifetime pricing model is financially accessible.
Where PharmX has limitations: The slides are a teaching resource, not a testing resource. Reading well-structured slides builds knowledge. It does not build the retrieval fluency that the exam tests under time pressure. PharmX does not have an adaptive question engine that responds to your individual performance. The platform does not tell you which of the 40+ therapeutic areas you are weakest in — you have to guess, and most candidates guess wrong. There is no native mobile app for on-the-go question practice.
Best for: The knowledge-building phase of revision — weeks 1-5, when you are learning the content before you start drilling it.
Coditioning
Coditioning occupies a distinctive position: it is as much an exam strategy platform as a question bank. The calculation strategy content is strong — worked examples, method frameworks, and the kind of exam technique coaching that helps candidates who know the content but lose marks through poor question technique. Over 1,000 questions covering SBA, EMQ, and calculation formats.
Where Coditioning is strong: Exam technique. If you understand the pharmacology but still get questions wrong because you misread stems, fall for distractors, or run out of time, Coditioning's strategy content addresses that directly. The calculation drilling is systematic, with worked examples that show the method before you attempt the practice. The CRA framework analysis is helpful for understanding what the exam is actually testing versus what you think it is testing.
Where Coditioning has limitations: The question bank is static rather than adaptive, so candidates must route themselves to weak topics. Explanations do not provide a live source-citation and update layer, and the platform is web-based without a native mobile app.
Best for: Candidates who need exam technique coaching — particularly those who have sat before and scored near the pass mark, where technique refinement rather than content knowledge is the marginal gain.
Focus Pre-Reg Revision
Focus Pre-Reg combines a question bank with live Zoom sessions, recorded therapeutics and medicines-reference teaching, and structured revision plans. Its main differentiator is taught interaction: a tutor explains the material, answers questions in real time and gives learners a schedule.
Where Focus Pre-Reg is strong: The live teaching may suit trainees who learn better through explanation and discussion than through self-directed reading. Recorded sessions can be revisited, while structured plans provide week-by-week direction for learners who struggle with organisation.
Where Focus Pre-Reg has limitations: Scheduling. Live sessions happen at specific times — if you are on shift, you miss them. Recordings are available but lose the interactive element. No adaptive engine. No performance dashboard showing topic-level proficiency. Web-based. The taught format means you progress at the course pace, not your pace — if you already know respiratory pharmacology but need help with endocrine, you still sit through the respiratory session.
Best for: Trainees who learn best from taught instruction and want interactive, live support alongside question practice.
The Format Match Problem Nobody Talks About
Here is something most comparison posts do not address: does the platform actually test you in the format the exam uses?
The CRA Part 2 includes 15 EMQ sets — extended matching questions where you have 8-10 options and 2-4 clinical scenarios sharing that option list. This is a fundamentally different cognitive task from an SBA. EMQs test your ability to discriminate between similar diagnoses or treatments across multiple scenarios simultaneously. Candidates who have only practised SBAs find EMQs harder — not because the clinical content is harder, but because the format requires a different approach (reading the option list first, not the scenario first; avoiding anchoring on early selections; using each option only once in most sets).
If your revision platform does not include EMQ-format questions, you are not practising 12.5% of the Part 2 paper. Check whether the platform you are considering offers EMQs — not all do.
Part 1 is 40 numerical free-entry questions. You type the number. If your calculation practice is multiple-choice (select 125, 150, or 175 mL/hour), you are not replicating the exam format. The free-entry format is harder because there is no option to eliminate, no "closest answer" to select, and no safety net of recognition. Only platforms that use numerical free-entry for Part 1 practice are replicating what you will actually face.
iatroX
iatroX provides questions organised around the CRA framework, performance-based sequencing, source-linked explanations where relevant, and mobile access. Check the live product for current question counts and formats, and use the official CRA framework and candidate resources to define assessment scope.
Where iatroX is strong: The three things the other platforms cannot offer.
First: the adaptive engine. After every question, the system updates your proficiency profile across all CRA content areas and selects the next question to target your weakest area. This is not a rotation. It is not a daily feed. It is a real-time response to your actual knowledge state. If your endocrine therapeutics proficiency is 40% but your cardiovascular is 80%, the engine serves more endocrine questions until the gap closes — then moves to your next weakest area. No other GPhC platform does this.
Second: source-linked explanations. Where relevant, iatroX explanations can cite NICE guidance or a product-specific SmPC on eMC. The citation lets candidates inspect the current source; it should not be taken as a guarantee that every explanation updates automatically whenever a source changes.
Third: the mobile app. iOS and Android. Native, not a wrapped web page. Your commute, your lunch break, your dispensary downtime — all become adaptive revision time. No other GPhC platform has this.
Where iatroX has limitations: It is a self-directed adaptive platform, not a taught course: there is no live Zoom teaching, tutor-led therapeutics walkthrough or live Q&A. Candidates who need concepts explained before testing may need a separate teaching resource. The question bank is growing but may still contain fewer items than some established competitors.
Best for: The testing phase of revision — from week 3 onwards, when you have the foundational knowledge and need to convert it into exam-ready retrieval fluency. And for candidates who revise on mobile, which is most of them.
Pricing: £29/month or £99/year at iatrox.com/quiz-landing?exam=uk-gphc.
The Combination That Works
What most high scorers figure out by week six of revision is that the revision tools serve different phases — and the candidates who use the right tool at the right phase outperform those who use one tool for everything.
Weeks 1-4 (knowledge building): Use PharmX slides, Focus Pre-Reg teaching or another structured resource to cover the domains in the official CRA framework. Build enough conceptual knowledge for applied question practice, then test it under timed conditions.
Weeks 3-8 (knowledge testing): iatroX adaptive Q-bank. Convert passive knowledge into active retrieval fluency. Let the adaptive engine identify your weak areas rather than guessing. Use the performance dashboard to track progress weekly.
Throughout (exam technique): Coditioning strategy content. Particularly valuable for calculations technique and EMQ approach.
Throughout (guideline verification): Ask iatroX. When a question explanation raises a "what exactly does NICE say?" query, get the cited answer in seconds.
The answer is not "one platform wins." The answer is "a structured notes platform plus an adaptive MCQ engine is the combination that works." The structured platform builds knowledge. The adaptive engine converts it into exam performance. The candidates who understand this distinction pass at higher rates than those who do not.
