Pearson Edexcel International A Level Chemistry (WCH11–WCH16): examiner-style marking and a new paper for every student
Mechanisms, calculations and extended answers marked for the specific marking points, with the lost mark tied to the concept behind it.
Specification first teaching 2018. A redeveloped IAL Chemistry is announced for first teaching Sept 2027 · January and June and October series · grades A*–E

Questions teachers ask
- Is this official Pearson Edexcel marking?
- No. Pearson Edexcel International marks the real exam. This is examiner-style marking of mocks and homework for IAL Chemistry, and you approve every mark before a student sees it.
- Do you reproduce past-paper questions?
- No. Every WCH11–WCH16 paper here is original and written to the specification first teaching 2018. a redeveloped ial chemistry is announced for first teaching sept 2027, 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?
- January and June and October series. Grades A*–E.
