AQA GCSE Science: CAU

ISA | PSA | 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 sections: ISA and PSA.

ISA: Investigative Skills Assignments

This is by far the most important aspect of the CAU. It is worth 34 marks in total and consists of two parts: a practical investigation and a written paper.

PSA: Practical Skills Assessment

The PSA is worth 6 marks. Your teacher will assess your practical ability over the whole course.
