AQA GCSE Science: CAU

ISA | Glossary

The three GCSE sciences approach coursework in the same way: this section is relevant to all.

Most students do all three sciences as a double award (i.e. Core then Additional) and will do two CAUs: one for each level. You may do more, but only two will be submitted.

If you're doing separate sciences, you will need to submit one CAU for each of Biology, Chemistry and Physics.

Sections

One of the best things about the CAU is that their format is almost identical across the Sciences: once you learn something in one, it applies to the others. There are two written papers known as the ISA.

ISA: Investigative Skills Assignments

This is by far the most important aspect of the CAU. It is worth 50 marks in total and involves researching, planning, carrying out and analysing an experiment. All of this is assessed through two written papers, completed in school time under exam conditions.
