📚 AQA A-Level Chemistry Entries and Codes | AQA A-Level 化学报名与代码
Understanding AQA entry codes is essential for centres, private candidates, and exam officers. This guide explains how AS and A-level Chemistry entries are structured, what the qualification and component codes mean, and how they link to assessment.
理解 AQA 报名代码对考点、独立考生和考务人员都很重要。本指南解释 AS 和 A-level 化学考试的报名结构、资格证书与试卷代码的含义，以及它们如何与测评关联。
1. Qualification Codes at a Glance | 资格证书代码一览
AQA AS Chemistry uses entry code 7404, while AQA A-level Chemistry uses entry code 7405. These codes identify the qualification, not a single exam paper. Centres enter candidates for the qualification, and AQA then timetables the relevant written components automatically.
AQA AS 化学的报名代码为 7404，AQA A-level 化学的报名代码为 7405。这些代码标识的是资格证书，而不是某一份试卷。考点为考生报名资格证书后，AQA 会自动安排相应的笔试组成部分。
| Qualification | 资格证书 | Entry code | 报名代码 | Written papers | 笔试 | Structure | 结构 |
|---|---|---|---|
| AS Chemistry | 7404 | 2 | Standalone qualification |
| A-level Chemistry | 7405 | 3 | Linear qualification |
2. AS Paper Codes and Structure | AS 试卷代码与结构
AS Chemistry consists of two written papers. Paper 1 (7404/1) covers inorganic and physical chemistry, and Paper 2 (7404/2) covers organic and physical chemistry. Each paper is 1 hour 30 minutes, carries 80 marks, and contributes 50% of the AS qualification.
AS 化学由两份笔试组成。试卷一（7404/1）涵盖无机和物理化学，试卷二（7404/2）涵盖有机和物理化学。每份试卷时长为 1 小时 30 分钟，满分 80 分，各占 AS 资格证书总成绩的 50%。
Although practical skills are not a separate AS paper, questions testing apparatus, measurement, variables, and safety can appear in both papers.
虽然实验技能不是一份单独的 AS 试卷，但考查仪器、测量、变量和安全知识的题目可能会出现在两份试卷中。
3. A-level Paper Codes and Structure | A-level 试卷代码与结构
A-level Chemistry is assessed by three written papers. Paper 1 (7405/1) covers inorganic and physical chemistry; Paper 2 (7405/2) covers organic and physical chemistry; Paper 3 (7405/3) focuses on practical skills, data handling, and synoptic content. Papers 1 and 2 are 2 hours long and carry 105 marks each, while Paper 3 is 2 hours long and carries 90 marks.
A-level 化学通过三份笔试进行考核。试卷一（7405/1）涵盖无机和物理化学；试卷二（7405/2）涵盖有机和物理化学；试卷三（7405/3）侧重实验技能、数据处理和综合内容。试卷一和试卷二时长为 2 小时，满分各为 105 分；试卷三时长为 2 小时，满分为 90 分。
The weightings are: Paper 1 35%, Paper 2 35%, and Paper 3 30%.
权重为：试卷一占 35%，试卷二占 35%，试卷三占 30%。
4. How Entry Codes Map to Components | 报名代码如何对应组成部分
In AQA's linear A-level Chemistry, candidates do not enter each written paper separately. A single A-level entry using 7405 automatically enters the candidate for 7405/1,
