Marlbridge's summary of the course

Our A Level Chemistry A qualification is a content-led course designed to develop theoretical and practical chemistry skills, knowledge and understanding.

The board's own description is on the official OCR syllabus page.

Qualification number 601/5255/2. Sibling AS Level Chemistry A is H032, qualification number 601/5256/4 — not recorded as a separate matrix row (this repo records A Level codes, not AS siblings, for other boards too).

Specifications change between examination series. Always confirm the current syllabus and assessment structure on the OCR syllabus page for your examination year.

Assessment components for OCR Chemistry H432
Component Duration Marks Weighting Type
H432/01: Paper 1: Periodic table, elements and physical chemistry 2h 15m 100 37% Written exam
H432/02: Paper 2: Synthesis and analytical techniques 2h 15m 100 37% Written exam
H432/03: Paper 3: Unified chemistry 1h 30m 70 26% Written exam

Source: official OCR specification, verified 2026-08-28. Directly confirmed against OCR's own official A Level Chemistry A (H432) "Assessment story: exploring our question papers" guide (2026-08-28). Three examined components: Paper 1 "Periodic table, elements and physical chemistry" and Paper 2 "Synthesis and analytical techniques" are each 100 marks/2h15/37%; Paper 3 "Unified chemistry" (all modules, synoptic) is 70 marks/1h30/26%. Total 270 marks across the three papers determines the overall A*-E grade. A separate Practical Endorsement (non-exam assessment, minimum 12 practical activities, internally assessed) is reported separately as Pass/Not Classified and does not contribute marks to the 270-mark grade; it is not listed as a component in the table because it carries no marks towards the 270-mark total.
