You can build a serious CRA preparation foundation at zero cost.
iatroX GPhC Q-bank (free). Adaptive, spaced repetition, mobile app, explanations grounded in NICE guidance, with medicines information from SmPCs via eMC. The only free adaptive GPhC revision tool.
Official CRA preparation sources. Start with the GPhC registration-assessment framework, sample questions and candidate guidance, and practise navigating the medicines resources supplied in the assessment. Use relevant SmPCs on eMC and applicable guidance for follow-up learning outside the exam.
GPhC official example questions (free). Authoritative calibration — shows exactly what the exam looks like.
Pharmaceutical Journal preparation series (free/verify). Three-part framework-based revision guide from RPS.
CPPE modules (free). NHSE-funded CPD covering clinical therapeutics and professional development.
NICE CKS (free). Clinical management pathways — directly relevant to Part 2 therapeutics.
Gaps in the free stack: Mock exams (most require paid access), structured courses (paid), peer benchmarking (Passmedicine). The free stack covers 70-80% of what you need. The remaining 20-30% is where low-cost tools (Pharm Educate, PharmRev) or course platforms (Pre-Reg Shortcuts) fill in.
