OCR A-level Chemistry past papers and mark schemes
27 papers · June 2017 – June 2024
27 files sit on this page for OCR A-level Chemistry A (H432), and each one has a mark scheme alongside it. They are grouped under Component 01 (Periodic table, elements and physical chemistry), Component 02 (Synthesis and analytical techniques) and Component 03 (Unified chemistry), with 9 papers under each heading. The exam series run from June 2017 to June 2024, giving 24 papers from real sittings, and 3 specimen papers are listed as well.
One approach is to pick a component, sit its oldest paper in timed conditions and mark it honestly with the mark scheme before moving on to the next series. Keeping the June 2023 and June 2024 papers back until nearer the exam gives you unseen practice when you need it. The files open on Physics & Maths Tutor.
Reschedule, an independent revision planner, turns your exam dates into a day-by-day plan. Because each paper has its own date, every subtopic is scheduled before the paper that examines it, and the past papers for that paper are slotted in with their mark schemes. If a day goes wrong, unfinished tasks move to your next study days and still land before each paper's date.

Common questions
- Where can I find OCR Chemistry mark schemes?
- Every paper on this page has its mark scheme linked in the same row. Each link opens the PDF where it is hosted.
- Which years of OCR Chemistry past papers are here?
- The page lists 24 papers from 8 exam series, June 2017 to June 2024, and 3 specimen or sample papers.
- How are OCR Chemistry past papers organised on this page?
- Papers are grouped by exam paper, then by series with the newest first: Component 01 (Periodic table, elements and physical chemistry), Component 02 (Synthesis and analytical techniques) and Component 03 (Unified chemistry).
- Are these the official OCR papers?
- They are the papers set by OCR. Links open the PDF where it is hosted: 27 on Physics & Maths Tutor. Reschedule is independent and not affiliated with any exam board.
- How do I fit past papers into my revision plan?
- Add Chemistry and OCR in Reschedule with the date of each paper. It builds a daily revision plan that schedules each subtopic before the paper that examines it and adds past papers for each paper, then re-fits the plan if you miss a day.
