Chemistry GCSE

IGCSE Edexcel specification

Why Study Chemistry? 

The Edexcel International GCSE course offers pupils the opportunity to gain an exciting insight into the chemical processes that underpin modern life: from the manufacture of fertilizers to the design of new biodegradable plastics. Combating global warming could partly depend upon the design of new carbon-neutral materials and chemical processes. There is a strong emphasis on practical work and the learning of key laboratory skills and techniques.

The course provides a strong basis for further study in Advanced Level Chemistry, which is a vital qualification for careers in pharmacy, medicine, chemical engineering, and climate change.
