AS/A-level Biology Revision

Biology is a natural science studying life and living organisms. This discipline provides a basis for many science-related degrees and is therefore essential for most budding scientists as well as prospective medical and dental students. A-level students explore the science of genetics, DNA structure and cells, learn about various body systems and familiarise themselves with biology and disease.

Below is a table of topics students are expected to cover according to their specific exam board:
