📚 CIE AS Information Technology: Exam Preparation Guide & Past Paper Analysis | CIE AS 信息技术备考攻略与真题解析

The Cambridge International AS Level Information Technology (9626) course equips students with both theoretical knowledge and practical skills in the digital world. This guide breaks down the syllabus, reveals high-frequency exam topics, and provides a structured revision plan based on past paper analysis — helping you maximise your score in both Paper 1 (Theory) and Paper 2 (Practical).

剑桥国际AS Level信息技术（9626）课程旨在培养学生在数字世界中的理论知识与实践技能。本指南将深入剖析考纲、揭示高频考点，并基于真题分析提供系统化的复习计划——帮助你在卷1（理论）与卷2（实践）中双双取得最高分数。

1. Understanding the Syllabus & Assessment Structure | 了解考纲与评估结构

Before diving into revision, you must understand how the exam is structured. The AS Level IT qualification comprises two papers, each contributing equally to your final AS grade. Paper 1 is a 1-hour-30-minute theory paper worth 50% of the AS marks, and Paper 2 is a 2-hour practical paper also worth 50%. Both papers test content from the six theory chapters and five practical chapters respectively.

在开始复习之前，你必须了解考试的结构。AS Level信息技术资格由两卷组成，每卷各占AS总成绩的50%。卷1为1小时30分钟的理论考试，占AS成绩50%；卷2为2小时的实践考试，同样占50%。两卷分别考查六个理论章节和五个实践章节的内容。

Past paper analysis shows that Paper 1 rewards precise terminology and structured explanations, while Paper 2 rewards speed and software command. You cannot simply memorise theory — practical fluency is equally important.

真题分析显示，卷1注重精准术语和结构化解释，而卷2则注重速度和软件熟练度。你不能只死记硬背理论——实践操作的熟练程度同样至关重要。

2. Paper 1 Theory: Core Content Breakdown | 卷1理论：核心内容拆解

Paper 1 draws on six chapters: Data and Information; Hardware and Software; Monitoring and Control; Algorithms; E-commerce; and ICT in Society. Among these, Data and Information appears most frequently, accounting for roughly 20% of the theory marks in recent series. Key subtopics include data validation, verification, and the difference between data, information, and knowledge.

卷1涵盖六个章节：数据与信息、硬件与软件、监控与控制、算法、电子商务以及信息技术在社会中的应用。其中，数据与信息章节出现频率最高，近几次考季约占理论分值的20%。核心子主题包括数据验证、校验，以及数据、信息和知识之间的区别。

Hardware and Software is the second most-tested area. You should be able to describe input/output devices, storage media, and the functions of operating systems. Questions often present a scenario — such as a supermarket checkout or a school library — and ask you to recommend suitable devices with justifications.

硬件与软件是第二大高频考查领域。你需要能够描述输入/输出设备、存储介质以及操作系统的功能。题目通常给出一个场景——例如超市收银台或学校图书馆——并要求你推荐合适的设备并说明理由。

• Data: types, validation, verification, encoding | 数据：类型、验证、校验、编码

• Hardware: input, output, storage, processors | 硬件：输入、输出、存储、处理器

• Software: system vs application software | 软件：系统软件与应用软件

• Monitoring and control: sensors, ADC, feedback loops | 监控与控制：传感器、模数转换器、反馈回路

• Algorithms: flowcharts, pseudocode, trace tables | 算法：流程图、伪代码、跟踪表

• E-commerce: B2B, B2C, C2C, advantages and disadvantages | 电子商务：B2B、B2C、C2C、优缺点

• ICT in society: health, environment, education, ethics | 信息技术在社会中的应用：健康、环境、教育、伦理

When answering theory questions, always define key terms first, then explain, then give an example. This “define–explain–example” structure consistently earns top marks in CIE mark schemes.

回答理论题时，务必先定义关键术语，再解释原理，最后给出例子。这种”定义—解释—举例”的结构在CIE评分标准中始终能获得高分。

3. Paper 2 Practical: Skills & Techniques | 卷2实践：技能与技巧

Paper 2 is a computer-based exam covering spreadsheets, databases, word processing, web page design, and sound/video editing. The most heavily weighted practical tasks are spreadsheets and databases, together representing roughly 60% of the practical paper. You will be given a scenario file and must complete a series of tasks using software such as Microsoft Excel, Access, and Word.

卷2为上机考试，涵盖电子表格、数据库、文字处理、网页设计以及音频/视频编辑。权重最高的实践任务是电子表格和数据库，合计约占实践卷的60%。你会拿到一个场景文件，并需要使用Microsoft Excel、Access和Word等软件完成一系列任务。

For spreadsheets, master the following formula families: IF and nested IF, VLOOKUP, COUNTIF/SUMIF, and data validation. In recent past papers, candidates frequently lose marks because they confuse relative and absolute cell referencing. Remember: absolute references use $ signs, such as $B$2, and do not change when copied.

对于电子表格，必须掌握以下公式族：IF与嵌套IF、VLOOKUP、COUNTIF/SUMIF以及数据验证。在近年真题中，考生常因混淆相对引用和绝对引用而失分。记住：绝对引用使用$符号，如$B$2，在复制时不发生变化。

=IF(D2 ≥ 40, “Pass”, “Fail”)

The formula above is a typical Paper 2 task: award “Pass” if the score in cell D2 is 40 or greater, otherwise “Fail”. Notice that text strings in formulas must be enclosed in double quotes.

以上公式是典型的卷2任务：如果D2单元格中的分数大于或等于40，则判定为”Pass”（通过），否则为”Fail”（不及格）。注意公式中的文本字符串必须用双引号括起来。

For databases, you must be comfortable with creating
