About this part of the site
This part of Chemguide provides support for the Edexcel Chemistry for International GCSE books of which I am either the author or joint author.
It is important that you are using the correct book, because the second one reflects syllabus changes for exams taken from June 2019 onwards.
Edexcel International GCSE Chemistry
This is the book to use if you are doing your exam before June 2019. Some books will also carry the title Edexcel Certificate in Chemistry. It is exactly the same book.
Edexcel International GCSE (9 - 1) Chemistry
This book exactly matches the syllabus that will be examined for the first time in June 2019.
This will take you to the main (advanced) part of Chemguide.
