Topic Questions: 3 assess the uncertainty in a derived quantity by simple addition of absolute or percentage uncertainties — 9702 P1 Errors and uncertainties
10 9702 P1 Errors and uncertainties topic questions are tagged to this syllabus point across 10 papers (2025–2026). Only the parts whose knowledge graph matches this syllabus statement are counted, and the table shows which parts of each question are involved.
Core finding
This Errors and uncertainties syllabus point appears in 10 9702 P1 papers across 2025–2026, contributing 10 topic questions and 10 marks. The most recent appearance is 9702/11 May/June 2026. That equals 62.5% of the 16 topic questions and 62.5% of the 16 marks tagged to Errors and uncertainties. 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.

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 10 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 2025–2026. 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.
