OCR A-level Chemistry A H432 past papers
Where OCR publishes its own H432 question papers and mark schemes, and what each of the three papers is: read off the specification, Version 3.1, May 2026.
Where to get them
OCR publishes them itself, on OCR’s assessment page for Chemistry A H032/H432. Checked against OCR’s own listing on 29 October 2026. The link opens at the A Level series list; the same page carries the AS H032 list below it, and the component code beside each file is what tells the two apart.
