Section 1 by Topic and Year

Section 1：专题 × 年份

261 Round 1 Section 1 questions, 2011–2025, placed in 21 topics.

2011–2025 年 Round 1 Section 1 共 261 道题，归入 21 个专题。

Each cell counts the questions from that year filed under that topic in our category question book. Read across a row to see how steadily a topic recurs; read down a column to see how a year’s paper was spread. A question is referred to by year and item letter, so 2023 Q1(m) is item (m) of the 2023 Section 1 paper. 2023 Q1(g) is filed under two topics, which is why the rows add up to 262 while the paper count is 261. Question text is not reproduced here: read the papers on the official site, or in the books below.

每一格是该年份归入该专题的题目数，依据本站的分类题集统计。横着读，看一个专题出现得有多稳定；竖着读，看一年的试卷怎样分布。题目按年份加小题字母称呼，例如 2023 Q1(m) 即 2023 年 Section 1 的第 (m) 小题。2023 Q1(g) 同时归入两个专题，所以各行合计为 262，而实际题数是 261。本页不转载题目原文：请到官网或下方的题解书里阅读原题。

To check your answer to any of these questions, open the Section 1 question bank (answers only). Items marked with a module code have a full walkthrough in the interactive lab.
