Section 1: Short Questions

Section 1：短题

A run of short questions across the whole syllabus, about an hour, up to 50 marks. The same topics come back every year.

覆盖整个大纲的一串短题，约一小时，最多 50 分。同样的专题每年都会回来。

Section 1 is where preparation pays most directly. Each item is short enough to master in one sitting, and our index of every Section 1 question from 2011 to 2025 shows the same handful of types returning in recognisable forms. The four tools below approach it from different sides: check answers in the bank, work the recurring types in the lab, follow the priority order in the Top Gold plan, and find every question on a topic in the index.

Section 1 是备考投入回报最直接的部分：每道题短到一次就能吃透，而我们对 2011–2025 年全部 Section 1 题目的索引显示，同样几类题每年以相近的面目回来。下面四个工具从不同角度切入：在题库里核对答案，在互动练习里把常考题型做一遍，按 Top Gold 方案的先后顺序复习，再用索引找到某个专题的全部题目。
