GCSE Chemistry

Main body content

Why study Chemistry?

Chemistry is an engaging science concerned with the composition, structure and properties of matter, as well as the changes it undergoes during chemical reactions. Students acquire deeper knowledge of the world around them, by gaining an understanding of phenomena such as:

  • The different types of chemical reactions
  • The types and properties of materials
  • Why crude oil is such a useful resource
  • The Periodic Table
  • Gases in the atmosphere and what they are used for
  • Industrial chemistry

GCSE Chemistry is a popular subject at Chelsea Independent College, attracting bright students who are keen to obtain a GCSE in an interesting, highly respected and challenging subject. Frequently they progress on to study chemistry at A Level which can, in turn, lead to university courses such as Medicine, Dentistry, Veterinary Science, Pharmacy, Engineering and Material Science. It is a highly respected qualification, the study of which enables students to not only become more knowledgeable of the world, but also to gain important problem-solving skills which can be applied to many areas of life.

How is it examined?

The Edexcel iGCSE (9-1) in Chemistry comprises two externally assessed papers:

  • Chemistry Paper 1
  • Chemistry Paper 2

Paper 1 is a 2-hour examination set and marked by Edexcel.  Total marks = 120 and represents 66.7% of the total qualification marks.  Grades available are A* - G.  Paper code = 4CH1/1C

Paper 2  is a 1-hour examination set and marked by Edexcel.  Total marks = 60 and represents 33.3% of the total qualification marks.  Grades available are A* - G.  Paper code = 4CH2/2C

Practical laboratory work

As part of the course, students must complete a series of core practical investigations, during which time they must develop a set of practical techniques, such as the ability to follow instructions, to understand how to select and use apparatus, how to work safely, and how to gather, analyse and report experimental data.
