The Cambridge IGCSE Physics 0625 syllabus (2026 to 2028) is available free from the Cambridge International website. This is the definitive reference for what can be examined. Every revision decision should start here.
Past papers and mark schemes
Cambridge publishes past papers, mark schemes and examiner reports for the 3 most recent exam sessions. These are available from the Cambridge International website or through your school/exam centre.
How to use them: work through papers under timed conditions, then mark against the mark scheme. The examiner report tells you what candidates typically got wrong.

General advice on using online resources
- Start with the syllabus. Use it as a checklist. Only study material that is on the syllabus.
- Verify the exam board. IGCSE Physics (Cambridge 0625) is different from Edexcel IGCSE Physics or AQA GCSE Physics. Make sure the resource matches your exam board.
- Past papers beat everything. No video, app or website replaces the practice of attempting real exam questions under timed conditions.
- Limit passive consumption. Watching videos and reading notes feels productive but does not build the problem-solving skills tested in the exam. Active recall and practice questions are what move your grade.
