GCSE Chemistry Revision Notes

These detailed GCSE Chemistry notes (over 150 pages) cover the entire syllabus for the Edexcel iGCSE Chemistry (9 – 1) specification. However, the contents of these notes are universal for all exam boards, because the topics are vastly similar.

The notes have been used by Grade 9 students, and have been compiled to be specific with the most important information required to learn the content.

Each specification point is written as a heading and has explanations, diagrams and tables beneath it. There are also many Past paper questions throughout the document which have been added to the appropriate section, as students have found these difficult in the past and they are important to learn. All required definitions are highlighted in green in the document and outlined at the top of each of the specification point headings. These revision notes contain ALL required Practicals in full detail, with methods diagrams and conclusions as appropriate.
