These topics are shared with the separate sciences. Your course covers a little less in places, so now and then a question may go further than you need. Count those as a bonus.
The topics follow the Cambridge IGCSE Combined Science (0653), syllabus for examination in 2025, 2026 and 2027. The questions are Papermunch’s own, written for revision: none of them are taken from past papers. For the real thing, theCombined Science past papers are on the shelf.
