CHEMISTRY

The following information shows the topics covered as part of the Separates (Triple) GCSE Chemistry course. Take extra care to note that there is extra content in this course that is not covered in the Trilogy (Combined) GCSE for Science. I have highlighted content that is for Chemistry only in red. The table of information has been taken from the official AQA GCSE Chemistry Course Specifications.
