Cambridge IGCSE
International 🌍FoundationsCambridge IGCSE — tiered Core and Extended practice for eleven subjects, from Mathematics 0580 to Computer Science 0478.
📏 IGCSE subjects are tiered: Core candidates sit the shorter objective and structured papers for grades C to G, Extended candidates sit the same papers at a harder tier plus the Supplement, for A* to E. Typical weightings are 30-40% for the objective paper, 50-60% for the structured/theory paper and 20% for the practical or alternative-to-practical paper; syllabus codes and windows are printed on the question papers.
