This directory is the starting point for every Cambridge IGCSE subject on the site. Each subject has a learning guide, topic lessons that explain one skill at a time, practice sets with worked answers, and pages for the difficulties students meet most.
Subjects are grouped into families below, so you can move between related subjects such as the sciences or the languages.
If you are not sure which syllabus code or exam year applies to you, start with the syllabus and exam-year navigator. It gives you a checklist for confirming the right code with your school or exam centre, so you do not study material meant for a different year.
How to use a subject section
- Read the learning guide to see how the subject is structured and how to study it.
- Choose a topic area and work through its lessons in the order suggested.
- Attempt the practice set before reading the answers. Use the routing notes to find which lesson to revisit.
- Move to tuition if a topic still does not settle. Every subject has a one-to-one tuition page explaining how the paid one-hour trial works for it.
