All three separate subjects taken together at Key Stage 4 represent a balanced science course, and this is the best foundation for the further study of these subjects at Advanced Level.
The syllabus is laid out in terms of units - The nature of Science, Diversity of Organisms, Biotechnology, Life Processes, Genetics and Environment.
If pupils think they may wish to continue into 'A' level Biology, they are strongly recomended to study GCSE Chemistry along with GCSE Biology.
