The best free IGCSE revision sites are Dr Dabour Hub for science lessons and quizzes, Physics & Maths Tutor for past papers by topic, ZNotes for short notes, and Cambridge International itself for the official syllabus and specimen papers. Using two of them together (notes plus past-paper practice) covers most of what a paid site offers.
- Dr Dabour Hub: free IGCSE Biology, Chemistry and Physics, split by syllabus point, with notes, key terms and a marked quiz after each topic (5,467 IGCSE quiz questions).
- Physics & Maths Tutor: free past papers, topic questions and notes for IGCSE maths and sciences.
- ZNotes: free, concise IGCSE notes written by students across many subjects.
- Cambridge International: the official syllabus for each subject and specimen papers; always check the syllabus code and year.
- Save My Exams: some free IGCSE notes, with most questions and mocks on a paid plan.
- Khan Academy: free videos for the underlying concepts, not organised by IGCSE syllabus.

Cambridge International publishes specimen papers and syllabuses, and Physics & Maths Tutor sorts past-paper questions by topic. Practise with past papers once you have finished the notes for a topic.
How should I use free IGCSE revision sites?
