AQA GCSE · Biology, Chemistry & Physics
Required practicals, step by step.
At least 15% of the marks in your science exams come from practical work. Here are all 28 AQA required practicals, each with a diagram, the method, the variables and a worked example. The 7 marked Triple only are on the separate science GCSEs, not Combined Science.

Practise the exam questions too.
Every practical has a set of exam-style questions in the app, on the method, the variables, the maths and what the results mean. It opens to students soon: join the waitlist and we’ll email you once, when it does.
