Chemistry Resources by Examination Board
Chemistry is set and marked differently depending on the board, so this site organises its resources by examination board and qualification rather than as one generic version of the subject. Cambridge, Edexcel, AQA, OCR and IB each structure their Chemistry qualifications differently — in syllabus order, command words and question style — and the worksheets, topical questions, MCQs and mark schemes here are grouped to match whichever one a student is actually sitting.
Cambridge Chemistry
Cambridge is the only board on this site offering the full pathway in one place — O Level, IGCSE, AS and A Level — rather than a single qualification on its own. Resources are kept separate by level for exactly that reason: what counts as revision for an IGCSE student would be entirely new material for someone just starting O Level.

Edexcel's International GCSE and International A Level Chemistry follow their own specification and question style, distinct from Cambridge's equivalent qualifications. Resources are organised separately for each, rather than treated as interchangeable with another board's version of the same subject.

AQA Chemistry covers GCSE and A Level, with its own specification points, command words and exam format. Resources here follow AQA's own structure rather than a generic UK Chemistry syllabus.
View AQA Chemistry resources →OCR Chemistry
OCR Chemistry, like AQA, covers GCSE and A Level, with a specification and question style of its own. Resources are organised to match OCR's version of each qualification specifically, rather than assuming it's identical to another board's.
View OCR Chemistry resources →IB Chemistry
IB Chemistry follows its own current syllabus — first taught from August 2023 and first examined in May 2025 — organised around two themes, Structure and Reactivity, rather than the traditional numbered-topic structure other boards use. Resources here follow that same structure, at both Standard Level (SL) and Higher Level (HL).
