Questions teachers ask
- Is this official Cambridge marking?
- No. Cambridge International Education marks the real exam. This is examiner-style marking of mocks and homework for 0478, and you approve every mark before a student sees it.
- Do you reproduce past-paper questions?
- No. Every 0478 paper here is original and written to the syllabus for examination in 2026, 2027 and 2028, in the same structure as the real papers shown above.
- Which papers are marked?
- None yet are marked question by question. Practical exams sat at the centre are not marked here.
- How is the next paper chosen?
- From the marks a student lost: the concepts behind them are ranked by marks dropped, and the new paper weights those topics. It is the same syllabus and structure, with new questions.
- When are the exams?
- June and November series. Grades A*–G.
