Learners who opt to take Biology, Chemistry or Physics at A Level follow the AQA specifications.

All three sciences have a substantial practical component - learners have to complete a number of assessed practicals as well as practicals in normal lessons.

Biology

https://www.aqa.org.uk/subjects/science/as-and-a-level/biology-7401-7402 

The core content of A Level Biology consists of eight modules:

1 Biological molecules

2 Cells

3 Organisms exchange substances with their environment

4 Genetic information, variation and relationships between organisms

5 Energy transfers in and between organisms

6 Organisms respond to changes in their internal and external environments

7 Genetics, populations, evolution and ecosystems

8 The control of gene expression

Assessment is by three written papers each 2 hours long.
