Edexcel IGCSE Chemistry (4CH1) — 2024 Past Papers

Edexcel IGCSE Chemistry (4CH1) is mainly examined in the June series each year, with some subjects also offered in January. The 2024 papers on this page cover the one session that ran in 2024: June 2024. Pearson Edexcel publishes question papers and mark schemes after each session.

These are two distinct UK-origin qualifications run by separate awarding bodies. Edexcel IGCSE (subject codes start with 4 or similar) is awarded by Pearson; Cambridge IGCSE (subject codes are 4-digit numbers like 0610, 0625) is awarded by Cambridge International. Both are accepted by UK universities and most international institutions, and both are graded on the 9-1 scale for newer specifications. The syllabuses, paper structures and exam dates differ subject by subject — neither is universally "harder" than the other; choose based on what your school offers and which specification you've prepared for. Mark schemes and examiner feedback look quite different in style.

Yes — and LumiExams makes them easy to find. Pearson Edexcel publishes 4CH1 question papers, mark schemes (and examiner reports where released) as free educational materials after each session. The PDFs are © Pearson Education Ltd; LumiExams does not own these documents, we organise the official Edexcel PDFs by year and session so you can study with the same materials your teachers reference, and link directly to each file. For official syllabuses, registration and assessment policy, refer to qualifications.pearson.com.

Work through one full paper under timed exam conditions, mark it against the official mark scheme, then read the examiner report for that session (where Pearson has published one). The examiner report calls out where students lost the most marks and why — that's the highest-leverage revision target. Pearson updates the Edexcel specification roughly every 3-5 years, so the 2024 papers reflect the specification that was active in 2024. Before relying on these for the year you're sitting, check the current 4CH1 specification on the Pearson Edexcel website.

Pearson Edexcel releases past papers a few months after each exam session, so 2025 papers appear gradually rather than all at once. Expected timeline: June 2025 papers around late August or early September 2025, after the results release; January 2025 papers (for subjects with a January series) around March-April 2025. 2024 (shown above) currently has the most recent 4CH1 papers on LumiExams — new 2025 question papers and mark schemes will appear here as soon as Pearson publishes them.
