Pearson Edexcel UK GCSE (9–1) Chemistry 1CH0 revision checklist FAQ

Quick answers about this free revision checklist, how to use it for exam prep, and how it relates to the official syllabus.

What does the 2026 Pearson Edexcel UK GCSE (9–1) Chemistry 1CH0 syllabus cover?

This revision checklist mirrors the official Pearson Edexcel UK GCSE (9–1) Chemistry 1CH0 syllabus for the 2026 examination series. Every topic and sub-topic on the page is taken from the published syllabus document, so working through the list in order gives you full coverage of what your exam can assess. For the authoritative version, always cross-check with the latest syllabus PDF on your exam board's website before your final revision push.

How many topics are on the Pearson Edexcel UK GCSE (9–1) Chemistry 1CH0 exam?

The number of top-level topic groups varies by subject, but you can see the exact count on this page — each major heading in the checklist corresponds to one syllabus topic group, and each row below it is a syllabus-level sub-topic. Use the confidence column (1–5) to flag which sub-topics need more work, and re-score yourself weekly to track real progress instead of guessing.

How long should I spend revising for Pearson Edexcel UK GCSE (9–1) Chemistry 1CH0?

8–12 weeks of focused revision, covering 1–2 topic groups per week with weekly past-paper practice, is realistic for most GCSE / IGCSE students. Use this checklist to plan your weeks: filter by topics you have rated 1–3 and spend your first revision block there. Subjects with heavy practical or extended-writing components (e.g. sciences, English) need more past-paper time in the final block than the topic-by-topic phase.

What's the best order to revise Chemistry topics?

Revise in roughly the order the syllabus lists the topics — exam boards build later topics on earlier ones, so taking them in syllabus order avoids gaps. Once you have rated every topic, switch to weakest-first: filter the checklist by confidence ≤ 2 and prioritise those topics in your next study block. This is more effective than re-revising topics you already score 4–5 on.

Where can I find Pearson Edexcel UK GCSE (9–1) Chemistry 1CH0 past papers and mark schemes?

You can find past papers and mark schemes via Tutopiya's Past Paper Finder and on your exam board's official site. Once you have rated each sub-topic on this checklist, attempt past-paper questions on your weakest topics first — practising under timed conditions is the single best predictor of exam performance, more so than re-reading notes.

How do I download this revision checklist as a PDF or CSV?

Use the Download CSV or Print PDF button at the bottom of the checklist. CSV opens in Excel, Numbers or Google Sheets so you can sort by confidence and re-arrange revision order. The PDF is print-ready for offline use. A free Tutopiya account is required for download — this also unlocks the matching topic resources, notes and worked examples on the Learning Portal.

Is this Chemistry revision checklist free to use?

Yes, the checklist itself is free — you can view, score and re-score every topic on this page without an account. The CSV / PDF downloads and access to matching Tutopiya Learning Portal resources require a free account. There is no payment required at any point; teachers and parents can also use this checklist freely with their students.

Does this checklist match the latest Pearson Edexcel UK GCSE (9–1) Chemistry 1CH0 specification?

Yes. The topics and sub-topics on this page are drawn from the current 2026 Pearson Edexcel UK GCSE (9–1) Chemistry 1CH0 specification published by Pearson Edexcel. Exam boards occasionally tweak weighting or assessment structure mid-cycle, so do a quick sanity-check against the official syllabus PDF when you start your revision and again 4 weeks before the exam.
