As our name implies, PrepDone aims to get you prepared by:

Know exactly where your gaps are

Practise exam-style questions, get your answers marked and see exactly what you missed. Weak areas are refreshed and re-tested until they stick.

Everything you need in one place

Biology, Chemistry and Physics together in one structured AQA Combined Science course.

Exam Mode when the time is right

Build knowledge first, then move into personalised exam practice when it matters most, so there’s no early burnout.

Revise at your pace, not the class average

Follow a structured path around what you need, with more time where it matters, while leaving headroom for your other GCSE subjects.

We don’t promise the earth.

You do the learning. We keep refreshing it.
