OCR A Level
OCR A Level Chemistry A past papers
27 OCR A Level Chemistry A (H432) papers from 9 series, June 2017 to June 2025, with mark schemes and examiner reports. Each series opens OCR’s past papers page for H432, where you pick the paper.
What is free: OCR first gives each series to schools for mock exams. About 14 months after the exam, it goes on OCR’s public site and stays there for at least five years, and longer for maths and science.
What is held back: Until then, the most recent series are for teachers only, on OCR’s Teach Cambridge site.
