About this part of the site
This part of Chemguide provides support for the first edition of my Chemistry for International GCSE book written for the Edexcel syllabus.
It is only suitable if you are going to be taking your exam before June 2019.
If you are taking your exam in June 2019 or later, you should go to this page.
This will take you to the main (advanced) part of Chemguide.
