Chemistry International GCSE

What are the properties of atoms? How do substances interact through chemical reactions? Chemistry deals with topics like these. You'll be introduced to principles of chemistry and do experiments at home using everyday materials.

This course is one of our new Gold Star IGCSEs. Find out more about them here.



Course requirements

There are no formal entry requirements for this course, but you need to be able to read and write in English. This is an online course you will also need access to the internet.
