GCSE Additional Science

What is GCSE Additional Science?

GCSE Additional Science builds on the foundation of scientific theory covered during the GCSE Science course studied in Year 10. The three disciplines of Biology, Chemistry and Physics are still taught as integrated subjects to maximise the sharing of interrelated topics. The newly developed course combines the learning of scientific theory with an understanding of how science works. The course also acts as a preparation to go on to study Biology, Chemistry and Physics at A-Level.
