Where to find past papers (and how to use them)
Past papers under timed conditions are the single highest-value thing you can do. Here are the official sources for every board — always go to the exam board for the definitive paper and mark scheme.
Official sources (mark schemes included)
AQA

External links open in a new tab. Exam-board sites are the definitive source; third-party sites are for convenience.
How to actually use them
- Do it to time. An untimed past paper trains the wrong thing. Use the real duration.
- Mark it honestly against the mark scheme — and learn the command words so you answer what's actually asked.
- Log your weak topics and drill them — then re-test. That loop is where the marks come from.
