The GPhC Common Registration Assessment (CRA) is the national registration exam for pharmacists in the UK — a two-part assessment sat in a single sitting with no compensation between parts and a maximum of three lifetime attempts.
Part 1 contains 40 numerical free-entry calculation questions in 120 minutes — covering concentrations, dilutions, displacement volumes, dose regimens, infusion rates, pharmacokinetics, pharmacoeconomics, and quantities to supply. The November 2024 pass mark was 28/40 (70%), with nearly 30% of candidates failing on calculations alone.
Part 2 contains 120 MCQs in 150 minutes — 90 SBAs and 30 EMQs — covering clinical therapeutics, law and governance, regulation, and person-centred care. Questions test applied pharmaceutical judgement in realistic UK practice scenarios.
What Makes a Good GPhC CRA Revision App?
Dual-format coverage. Part 1 requires free-entry numerical calculations. Part 2 requires SBA and EMQ reasoning. Both formats need specific practice — a Q-bank covering only SBAs is inadequate.
Calculation depth. Nearly 30% failure rate on Part 1 makes calculations the highest-risk component. The Q-bank must cover the full calculation taxonomy with timed, free-entry practice — not multiple choice.
Applied scenario questions. Part 2 tests applied pharmacy care — prescribing decisions, monitoring, counselling, contraindications, interactions, law, and professional standards in realistic clinical contexts.
UK law and governance. Medicines Act, Misuse of Drugs Act, GPhC Standards, responsible pharmacist regulations, controlled drug requirements, and emergency supply provisions all feature in Part 2.
Mock exam mode. Both parts in a single sitting — reproducing the endurance and format of the real exam.
Where iatroX Fits
The iatroX premium pharmacist Q-bank covers both CRA parts — adaptive calculation drills for Part 1 (free-entry, difficulty-scaled) and SBA/EMQ clinical scenarios for Part 2, mapped to the 2026 CRA framework. Mock exam mode reproduces the full assessment format. Spaced repetition resurfaces missed concepts. Semantic adaptive learning identifies related weaknesses across therapeutic areas.
Ask iatroX provides SmPC/eMC-grounded medicines information alongside clinical clarification — when a Q-bank question reveals a knowledge gap, the pharmacist can check the medicines answer immediately.

GPhC CRA Exam Format and Key Facts
The GPhC CRA consists of Part 1: 40 free-entry calculations/120min. Part 2: 120 MCQs (90 SBA + 30 EMQ)/150min. Must pass BOTH in same sitting. The exam fee is ~£350. Candidates have 3 lifetime attempts. From 2026: LO37 (independent prescribing) excluded.
The dual-paper requirement with no compensation is the defining feature. A candidate scoring 95% on Part 2 but failing Part 1 must resit both papers. This creates a bimodal preparation challenge.
Part 1: Calculations
Part 1 tests pharmaceutical calculations: dilutions, concentrations, dosing by weight and BSA, infusion rates, moles/millimoles conversions, displacement values, and reconstitution. Questions are free-entry — no options, meaning calculation errors produce definitively wrong answers. Common failure patterns: unit conversion errors, failure to account for salt forms vs base forms, and arithmetic errors under time pressure. November sittings historically show lower pass rates (~62% vs ~77% in June).
Part 2: Clinical and Pharmacy Practice
Part 2 combines 90 SBAs and 30 EMQs covering medicines optimisation, clinical therapeutics, pharmaceutical science, and pharmacy practice. EMQs test pattern recognition across extended option lists. SBAs test single-best-answer discrimination in clinical and regulatory scenarios.
GPhC CRA Competitor Landscape
PharmaPro, Pharmacy Prep, and Pre-Reg Shortcuts offer dedicated GPhC revision. University materials provide foundation-level preparation. iatroX provides GPhC-specific coverage with separate SBA, EMQ, and Calculation question types — matching the actual exam format. Adaptive learning identifies whether weak areas are in calculations, clinical knowledge, or pharmacy practice, enabling targeted preparation for the specific component at risk.
Building an Effective GPhC CRA Study Strategy
Effective GPhC CRA preparation follows a structured progression from broad coverage to targeted consolidation.
Phase 1 — Foundation building (weeks 1-4 of a 12-16-week plan). Work through questions by topic area in untimed mode. The goal is broad coverage, not speed. Read every explanation thoroughly, including why incorrect options are wrong. Flag topics where understanding feels superficial rather than confident. Use iatroX's topic filters to ensure systematic coverage rather than gravitating toward comfortable subjects.
Phase 2 — Gap identification and targeted revision (weeks 5-8). Review analytics to identify persistent weak areas. Shift from broad coverage to targeted work on the topics where performance lags. iatroX's adaptive algorithm prioritises questions from areas where the candidate has demonstrated uncertainty, ensuring revision time is spent where it will have the greatest impact. Spaced repetition scheduling resurfaces previously answered questions at intervals optimised for long-term retention.
Phase 3 — Exam simulation and consolidation (final 4+ weeks). Transition to timed practice and full mock exams. Mock exams should replicate exam conditions as closely as possible — full-length, timed, with no interruptions. Review mock performance not just for content gaps but for pacing, question interpretation, and decision-making under time pressure. iatroX's mock exam mode generates exam-length papers that mirror the real assessment format.
Active recall vs passive reading. The evidence for active recall in medical education is robust. Answering questions, retrieving information from memory, and testing oneself are consistently more effective than re-reading notes or textbooks. A well-structured Q-bank provides the scaffolding for active recall — each question is a retrieval opportunity, each explanation is a learning event. Combined with spaced repetition, this produces durable knowledge that persists to exam day and beyond.
Analytics-driven adjustment. Static study plans assume every candidate starts from the same baseline and progresses at the same rate. Analytics-driven preparation — where study allocation adjusts based on actual performance data — is significantly more efficient. iatroX's dashboard shows per-topic accuracy, trend data, and comparison between areas, enabling candidates to make evidence-based decisions about where to spend their limited revision time.
Common GPhC CRA Preparation Mistakes
Over-relying on a single resource. No single Q-bank, textbook, or course covers everything. Candidates who use only one resource risk developing blind spots in areas that resource under-represents. The strongest preparation combines a primary Q-bank with supplementary reading and, where possible, a second source of practice questions for cross-referencing.
Studying topics rather than weaknesses. Candidates naturally gravitate toward topics they find interesting or already know well. Effective preparation requires the opposite — disproportionate time on the areas where performance is weakest. Analytics tools that track per-topic accuracy and flag persistent weak areas are essential for overcoming this tendency. Without data, candidates spend revision time reinforcing strengths rather than closing gaps.
Neglecting exam technique. Knowledge alone is insufficient. Candidates who never practise under timed conditions often find that exam-day time pressure degrades their performance by 10-15% compared to untimed practice. Regular timed practice and full-length mock exams build the pacing, endurance, and decision-making stamina that the real exam demands. This is a trainable skill, not an innate one.
Starting too late. Cramming produces short-term recall but poor long-term retention. Spaced repetition — revisiting material at increasing intervals — builds durable knowledge. Starting preparation early enough to allow multiple revision cycles produces significantly better outcomes than last-minute intensive cramming. A 16-week plan with moderate daily study consistently outperforms a 4-week plan with intensive daily study.
Ignoring incorrect answers. Many candidates check whether they got a question right and move on. The learning value is primarily in the explanation — understanding why the correct answer is correct, why each distractor is wrong, and what clinical reasoning links them. Candidates who spend time on explanations learn more per question than those who rush through high volumes without reflection.
How iatroX Supports GPhC CRA Preparation
iatroX provides several features specifically relevant to GPhC CRA candidates:
Adaptive question selection. Rather than presenting questions randomly, iatroX's adaptive algorithm analyses performance patterns and selects questions that target demonstrated weak areas. Revision time is spent where it will have the greatest impact on exam readiness, not reinforcing already-strong topics.
Spaced repetition scheduling. Previously answered questions are re-presented at intervals calibrated to the spacing effect. Incorrectly answered questions return sooner; correctly answered questions are spaced further apart. This produces durable long-term retention rather than fragile short-term recall.
Mock exam mode. Full-length, timed mock exams replicate the structure and time constraints of the real assessment. Mock analytics show per-topic performance, pacing data, and score trends across multiple attempts — enabling candidates to track improvement and identify persistent gaps.
Study planning. Personalised study plans based on exam date, available study time, and current performance level. Plans adapt as the candidate progresses, shifting emphasis toward areas where improvement is most needed.
Multi-platform access. Available on web, iOS, and Android — enabling revision during commutes, placements, and breaks without losing progress or analytics data. Progress syncs across all devices automatically.
Clinical AI integration. Ask iatroX provides guideline-grounded clinical queries powered by RAG over NICE, CKS, BNF, EMC, and NHS content — enabling candidates to verify management approaches against current UK guidelines during revision. Over 80 clinical calculators cover scoring systems and decision tools used in daily practice. CPD tracking with FourteenFish integration means the platform serves beyond exam preparation into ongoing professional development.
MHRA-registered platform. iatroX holds UKCA marking and MHRA Class I registration — a regulatory standard that most revision platforms do not hold, reflecting the platform's clinical decision support capabilities alongside exam preparation.
2026 Revision Strategy and Resource Checklist
Candidates should treat every revision resource as an exam-performance tool, not simply as a content library. The strongest platforms make the candidate practise the same cognitive task the real exam demands: reading a vignette, identifying the discriminating clinical clue, choosing the safest answer, and learning from the distractors. For this reason, the most useful comparison is not "which app has the most questions?" but "which app produces the most improvement per hour of revision?"
The key capability is pharmacy calculations, safe and effective pharmacy care, law, ethics and patient counselling. That means a revision app should provide more than topic filters. It should let candidates build a representative exam mix, practise in timed mode, revisit missed concepts, and see whether performance is improving across the domains that actually matter. The GPhC Common Registration Assessment information confirms the two-part structure: calculations in Part 1 and safe/effective pharmacy care in Part 2.
A practical way to evaluate a question bank is to inspect ten explanations before committing. Strong explanations usually do four things: they identify the diagnosis or principle being tested, explain why the correct answer is safer or more appropriate than the alternatives, show why the distractors are tempting but wrong, and link the point back to a repeatable exam rule. Weak explanations simply restate the answer. In high-stakes medical exams, that difference matters because candidates lose marks at the margin: two options may look plausible, but only one is most appropriate in that clinical context.
A Practical 16-20 weeks Study Workflow
A sensible GPhC CRA plan should begin with a mixed diagnostic block rather than a favourite topic. The purpose is not to score highly on day one; it is to expose the initial pattern of weakness. Once the baseline is clear, the first phase should focus on broad curriculum coverage. Candidates should work in untimed mode, read explanations carefully, and convert recurrent errors into a small number of revision rules: "what did I miss?", "what clue should have changed my answer?", and "what will I do next time I see this pattern?"
The second phase should become more selective. This is where iatroX's adaptive learning and semantic similarity approach become useful. Instead of merely showing that a candidate is weak in a large topic such as cardiology, respiratory medicine, paediatrics or prescribing, the platform can identify clusters of related errors across apparently separate labels. A candidate who repeatedly misses questions involving breathlessness, anticoagulation, heart failure and renal dosing may not have four unrelated weaknesses; they may have one underlying weakness in integrated cardiorenal decision-making. Targeting that root gap is more efficient than simply serving another random block from the same broad category.
The final phase should be dominated by timed work and mocks. Untimed practice builds knowledge, but timed practice builds the exam behaviour: reading stems efficiently, resisting overthinking, managing uncertainty and recovering after difficult questions. Candidates should deliberately practise dose calculation, renal adjustment, contraindications, monitoring, counselling and legal/professional safeguards. These are the areas where a good app should force active recall rather than passive recognition.
What iatroX Adds Beyond a Traditional Q-Bank
iatroX is positioned as a revision layer and a clinical reasoning layer. The question bank provides curriculum-mapped practice, mocks, spaced repetition and adaptive recommendations. Ask iatroX, calculators and CPD logging then connect that revision to clinical practice. This matters because most candidates are not revising in isolation; they are revising while working, on placement, preparing for another exam, or moving between health systems.
The practical advantage is continuity. A candidate can use iatroX for focused practice, switch to a mock, clarify a guideline-linked point, return to missed concepts through spaced repetition, and then use the same broader platform in clinical work. For candidates preparing for more than one assessment, multi-exam access also reduces duplication. Knowledge built for one exam often supports another, but only if the platform is organised around reusable clinical concepts rather than isolated exam silos.
Candidate Checklist Before Subscribing
Before choosing a revision resource, candidates should check:
Does it match the exam format? SBA, MCQ, EMQ, calculation, written response and case-simulation exams require different practice behaviours.
Does it map to the curriculum or blueprint? Large question volume is less useful if the distribution does not reflect the real assessment.
Does it support timed mocks? Exam performance depends on pacing and endurance, not knowledge alone.
Does it resurface missed concepts? Without spaced repetition, early revision decays while later topics are being covered.
Does it show actionable analytics? Topic percentages are useful, but the best systems identify the clinical reasoning pattern behind repeated errors.
Does it fit real working life? Mobile access, short practice blocks and continuity across devices are not luxuries for clinicians; they are what make consistent revision possible.
