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

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; recorded here as a 0-mark/0-weighting non-exam-assessment component to preserve that it exists without implying it adds to the 270-mark total.
