The international school qualification Nigerian families choose when they want a curriculum that travels: eleven subjects with published syllabus codes, most sat at Core (grades C-G) or Extended (A*-E) with the sciences adding a practical or alternative-to-practical paper. Computer Science 0478 is not tiered: it has a theory paper and a design-and-development paper, and Geography and History follow the same Core and Extended rule as the sciences. SabiMastery follows Cambridge's syllabus windows (Mathematics 0580 for 2025-2027, most other subjects 2026-2028) and keeps the two tiers apart, so a Core candidate never practises a Supplement question. Past papers are Cambridge's copyright: every question here is generated from the syllabus, not copied from a paper.
