Frequently Asked Questions

How is Edexcel GCSE Chemistry (1CH0) assessed?
Edexcel GCSE (9-1) Chemistry (1CH0) offers Foundation and Higher tiers, each assessed through two written papers covering all topics. Both tiers are externally assessed through written examinations sat at the end of the course; there is no coursework component. Balance chemical equations carefully and memorize key reaction types. Higher tier includes more complex stoichiometry.
Should I sit Foundation or Higher tier for Chemistry?
Your school decides which tier you sit, usually based on mock results and ongoing coursework. Foundation tier targets grades 1-5 and is the right choice if grade 5 would be a strong outcome; Higher tier targets grades 4-9 and is right when grade 6+ is realistic. If you sit Higher and underperform you can drop below grade 3 to "unclassified", so borderline candidates often play it safe with Foundation. Practise past papers from both tiers if you're undecided, then discuss with your teacher.
When are exam results and grade boundaries released?
Pearson Edexcel releases GCSE results in late August each year — typically on the third Thursday of August. Grade thresholds (the raw-mark cut-offs for each grade band) are published on the same day on the Pearson Edexcel website; they vary year to year and tier to tier to keep grades comparable across sessions. The 1CH0 grade boundaries archive on the Pearson site lets you check what raw mark scored what grade in each historical session.
Are these Edexcel 1CH0 past papers free and complete?
Yes — every Edexcel-published question paper, mark scheme and examiner report from 2022-2024 is included here as a direct link to the official Pearson PDF. The papers are © Pearson Education Ltd; LumiExams organises and links to them as free educational material, but does not own the documents. For the very latest exam-officer guidance, grade-boundary tables and specification updates, refer to the Pearson Edexcel website.
Edexcel GCSE vs Edexcel IGCSE Chemistry — what's the difference?
Edexcel GCSE (subject codes starting with "1", e.g. 1CH0) is the UK domestic GCSE used by schools in England and Wales. Edexcel International GCSE (IGCSE, codes starting with "4", e.g. 4CH0) is the international version used worldwide. Both are Pearson qualifications and both can be tiered or untiered depending on the subject, but the specifications, exam dates and grade-boundary calibration differ. UK universities accept either.
