Pearson Edexcel A-level Chemistry past papers and mark schemes
30 papers · June 2017 – June 2025
Paper 1: Advanced Inorganic and Physical Chemistry and Paper 2: Advanced Organic and Physical Chemistry are each worth 90 marks over 1 hour 45 minutes, while Paper 3: General and Practical Principles in Chemistry runs to 120 marks over 2 hours 30 minutes. This page collects past papers for the Pearson Edexcel A-level Chemistry specification, 9CH0, under those headings.
There are 30 papers in all, each with a mark scheme: 27 from exam series between June 2017 and June 2025, and 3 specimen papers. The series include October 2020 and November 2021 as well as the June sittings, sorted newest first under each paper. None of the Chemistry papers on this page has a separate insert. If you are early in the year, start with the older series and keep the most recent ones for the final weeks, so you still have unseen papers to sit close to the exam.
To fit those papers around your other subjects, try Reschedule, an A-level revision planner. Enter your subjects, board and the date of each paper, plus the days and hours you are free, and it builds a daily plan from the specification. Every subtopic is placed before the paper that examines it, and subtopics link to study material such as textbook chapters, Physics & Maths Tutor and Save My Exams.

Common questions
- Where can I find Edexcel 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 Edexcel Chemistry past papers are here?
- The page lists 27 papers from 9 exam series, June 2017 to June 2025, and 3 specimen or sample papers.
- How are Edexcel Chemistry past papers organised on this page?
- Papers are grouped by exam paper, then by series with the newest first: Paper 1: Advanced Inorganic and Physical Chemistry (1 hour 45 minutes, 90 marks), Paper 2: Advanced Organic and Physical Chemistry (1 hour 45 minutes, 90 marks) and Paper 3: General and Practical Principles in Chemistry (2 hours 30 minutes, 120 marks). Durations and marks are the most common values across the series listed.
- Are these the official Edexcel papers?
- They are the papers set by Edexcel. Links open the PDF where it is hosted: 30 on the Pearson website. Reschedule is independent and not affiliated with any exam board.
- How do I fit past papers into my revision plan?
- Add Chemistry and Edexcel 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.
