That equals 27.8% of the 36 topic questions and 14.9% of the 101 marks tagged to Proof. Only parts tagged to this subtopic are counted, so a four-part question can contribute one item and one part's marks. The table lists every matching question, its tagged parts and marks, with a link back to the paper page. Sessions are newest first, so the statement can be traced back through the full paper history. ## Topic questions by session Newest sessions first. Parts and marks count only the parts tagged to this subtopic; “x of y parts” shows how much of the question is tagged elsewhere.

[1.2 Proof by exhaustion](https://www.examsci.com/topics/edexcel-ial/mathematics/pure-mathematics-2-wma12/proof/1-2-proof-by-exhaustion/) — 10 question items · 10 papers — 34 marks · 2021–2025 ## Topic question rules and edge cases **How many topic questions cover this syllabus point?** 10 question stems cover this subtopic across 10 papers, but only 10 tagged parts and 15 marks belong to it. Other parts of the same questions are assessed under different statements and are excluded from this page. **Which papers include this subtopic?** The table lists every matching session from 2019–2025. Each row links to the question anchor on the paper page, where the full paper context and practice entry point are available. **Why can one question appear under several subtopics?** The parts of one question can assess different syllabus statements. Each part is counted under its own subtopics, so the same question stem can appear on several subtopic pages while each page lists only the parts and marks tagged to that statement. **Can I practise these questions with AI marking?** Yes. Open a paper from the table and use the Interactive Practice Hub entry point. The page itself is static HTML so search engines and retrieval agents can read the full question list without executing JavaScript. --- Full page with native tables, bar charts and Practice Hub links: https://www.examsci.com/topics/edexcel-ial/mathematics/pure-mathematics-2-wma12/proof/1-3-disproof-by-counter-example/
