A Level Chemistry 9701 topical past papers

Every question on 23 Cambridge 9701 Paper 1 papers from 2023 to 2025 — 920 questions — filed under the syllabus topic it tests. The biggest is Group 2 metals: properties and trends, with 53 questions on 23 of the 23 papers; next is Isomerism. Topics run biggest first, so reading down the page is also a revision order.

This is an index, not a copy. Cambridge publishes the papers and mark schemes; this page tells you where each topic’s questions are — paper code, question number and marks — and every paper links to a page where you can sit it online and have it marked.

How the questions were sorted

Each question was read against its published mark scheme and filed under the one syllabus topic it mainly tests, using the topic list in Cambridge’s own syllabus. A question that also draws on a second topic is listed once, under the first. Every question is worth one mark. The 9701 syllabus, topic by topic → The same topics ranked by share of the marks →

Common questions

Where can I find 9701 topical past papers?

This page is a free topical index: every question on 23 9701 Paper 1 papers, sorted by syllabus topic, with the paper code and question number to find it. Each paper links to a Quanta page where you can answer it online and have it marked against the published scheme.

Are these Cambridge's official topics?

The topics are Cambridge’s — the numbered topics of the 9701 syllabus. Which question tests which topic is Quanta’s reading of each question and its mark scheme; Cambridge does not publish that.

Which 9701 topic has the most questions?

Group 2 metals: properties and trends: 53 questions on 23 of 23 papers, 5.8% of the questions. Isomerism is next.
