Knowing the format of each paper will help you focus your study efforts effectively.
IGCSE 计算机科学 0478 资格证书通过两份必考卷进行考核。两份试卷通常在课程结束时（Year 11）参加，但全部大纲内容一般分布在 Year 10 和 Year 11 完成。了解每份试卷的形式有助于你高效地集中学习精力。
| Paper (试卷) | Duration (时长) | Marks (分数) | Weighting (权重) | Content (内容) |
|---|---|---|---|---|
| Paper 1: Theory of Computer Science (计算机科学理论) | 1 hour 45 minutes | 60 | 50% | All theory topics (全部理论主题) |
| Paper 2: Problem-solving and Programming (问题解决与编程) | 1 hour 45 minutes | 50 | 50% | Practical problem-solving, algorithms, programming (实际问题解决、算法、编程) |
Paper 1 consists of short-answer and structured questions that test your theoretical understanding. Paper 2 requires you to apply programming concepts, interpret pseudocode, and design solutions. There is no practical programming exam on a computer, but deep familiarity with a programming language such as Python is essential for Paper 2 success.
试卷一包含简答题和结构化问题，考查你的理论知识。试卷二要求你应用编程概念、解读伪代码并设计解决方案。虽然没有上机实操考试，但熟练掌握 Python 等编程语言对取得 Paper 2 的好成绩至关重要。
3. Paper 1: Theory of Computer Science in Depth | 深入 Paper 1：计算机科学理论
Paper 1 is the theory component and carries half of the final mark. It covers all the core theory topics specified by the syllabus, including data representation, hardware, software, networks, security, and ethics. Questions are varied in style – multiple choice, data entry, labeling diagrams, and extended writing. You need to demonstrate both recall of facts and the ability to explain concepts clearly.
试卷一是理论部分，占总成绩的一半。它涵盖大纲规定的所有核心理论主题，包括数据表示、硬件、软件、网络、安全和伦理。题目形式多样——有选择题、数据填写、图示标注和扩展写作。你既需要准确记忆事实，也需要清晰地解释概念。
Topics in Paper 1 are often interlinked. For example, a question might ask you to convert a binary number to denary, then explain how the binary number relates to an ASCII character, and finally discuss how the data could be compressed for transmission. This integrated approach rewards students who understand the connections between topics.
试卷一中的主题常常相互关联。例如，一道题可能要求你将一个二进制数转换为十进制，接着解释该二进制数如何与 ASCII 字符相关，最后讨论如何对数据进行压缩以便传输。这种综合性考查方式对理解主题间联系的学生更为有利。
Exam technique is crucial. Use precise technical vocabulary, annotate diagrams where required, and always relate your answers to the context given in the question. Time management is also important since the paper contains multiple sections requiring different amounts of writing.

10. Topic 6: Algorithm Design and Programming | 主题六：算法设计与编程
Algorithm design and programming ties together the practical aspects of the course. You will learn to express solutions using structured pseudocode and flowcharts, using standard symbols. The building blocks of any algorithm – sequence, selection, and iteration – must be grasped firmly. You will also handle variables, data types (integer, real, char, string, boolean), arrays (one- and two-dimensional), and file operations.
算法设计与编程将课程的实践方面串联起来。你将学习使用结构化伪代码和标准符号的流程图来表达解决方案。必须牢牢掌握任何算法的基本构建块——顺序、选择和循环。你还将处理变量、数据类型（整型、实型、字符、字符串、布尔型）、数组（一维和二维）以及文件操作。
Standard algorithms are a pivotal part of the examination: linear search, binary search, bubble sort, and possibly simple validation checks. You need to be able to trace an algorithm, identify errors, and suggest improvements. The concept of testing (normal, abnormal, boundary data) and maintainability (comments, indentation, meaningful identifiers) is also assessed in both papers.
标准算法是考试的关键部分：线性搜索、二分搜索、冒泡排序以及可能简单的验证检查。你需要能够追踪算法、识别错误并提出改进建议。测试（正常、异常、边界数据）和可维护性（注释、缩进、有意义的标识符）的概念在两张试卷中都会进行评估。
11. Assessment Objectives and Grade Boundaries | 评估目标与分数界限
The CAIE syllabus defines three assessment objectives (AOs) that underpin all examination questions. AO1 focuses on Knowledge and Understanding (recalling facts, concepts, and terminology). AO2 is about Application (using knowledge to solve problems in specific contexts), and AO3 is Analysis, Evaluation, and Problem-solving (analysing systems, drawing conclusions, refining solutions).
CAIE 大纲定义了三个评估目标 (AOs)，它们支撑着所有考试题目。AO1 侧重于知识与理解（回忆事实、概念和术语）。AO2 涉及应用（在特定情境中运用知识解决问题），AO3 则是分析、评估与问题解决（分析系统、得出结论、完善解决方案）。
Paper 1 typically has a higher proportion of AO1 and AO2 marks, while Paper 2 strongly tests AO2 and AO3 through algorithm design and debugging. Understanding this weighting helps you approach revision: ensure you can not only recall facts but also apply them and evaluate solutions critically. Grade boundaries vary from session to session, but aiming for a thorough understanding across all AOs is the most reliable path to an A*.
试卷一通常有更大比重的 AO1 和 AO2 分数，而试卷二通过算法设计和调试，重点考查 AO2 和 AO3。理解这一权重有助于你规划复习：确保你不仅能回忆事实，还能应用它们并批判性地评价解决方案。等级分数线每次考试略有波动，但全面掌握所有评估目标是通往 A* 的最可靠途径。
