Science Separate GCSE This option is aimed at students who enjoy the study of science and wish to study it in more depth. Any student who can demonstrate that they will commit themselves to extra study can opt for Separate Sciences. The course comprises more content but not higher-level work. However, some students do find this extra content challenging. This option will not affect the other option choices although students will need to demonstrate the ability to manage the overall work-load. Students study three extra units, over the two years of the course. At the end of the course students will be awarded separate GCSEs in Biology, Chemistry and Physics.
