Why PharmaSi Prep

Built for CRA preparation.

Not a generic question bank — practice designed for the GPhC Common Registration Assessment, written and checked by a practising pharmacist.

Exam-style questions

Single-best-answer and matching questions at real assessment pace — the format and difficulty you will meet on the day.

An explanation on every option

You are told why the right answer is right and why each distractor was written to tempt you — the part where the learning happens.

Two scores, weak topics ranked

An exam-condition score and a final score separate a pace problem from a knowledge gap, and your weakest topics become your revision list.

Full access

Full access for £19.99.

Everything you need to prepare for the GPhC exam. One simple price — one payment, no subscription.
