3. Paper 1: Computer Systems – Key Changes | 试卷1：计算机系统 – 主要变化
Paper 1 (1 hour 45 minutes, 75 marks) covers the theoretical foundations of computer science. With the revised syllabus, there is a noticeable shift towards applied scenarios rather than simple recall. Topics such as data transmission now include deeper questions on encryption and network security protocols, while 'Automated and emerging technologies' introduces AI, robotics, and expert systems, requiring analysis of their benefits and ethical dilemmas. Furthermore, Boolean logic questions are now integrated with circuit design more explicitly.
试卷1（1小时45分钟，75分）涵盖计算机科学的理论基础。随着大纲的修订，明显从简单记忆转向应用场景。数据传输等主题现在包括关于加密和网络安全协议的更深层次问题，而“自动化与新兴技术”引入了人工智能、机器人和专家系统，要求分析它们的优势和伦理困境。此外，布尔逻辑题目现在更明确地与电路设计结合在一起。
4. Paper 2: Problem-solving and Programming – Enhanced Focus | 试卷2：问题解决与编程 – 重点加强
Paper 2 (1 hour 45 minutes, 50 marks) now demands hands-on programming proficiency in one of the three recommended high-level languages: Python, Java, or C#. A crucial departure from older formats is the removal of pre-release material; students must read and interpret a problem statement during the exam and construct algorithms and code from scratch. The emphasis is on writing efficient, well-structured programs that include sequence, selection, iteration, arrays, and file handling, with error-free logic under time pressure.
试卷2（1小时45分钟，50分）现在要求熟练掌握三种推荐高级编程语言之一：Python、Java或C#。与旧格式的一个重要不同是取消了预发布材料；学生必须在考试中阅读并理解问题陈述，从零开始构建算法和代码。重点在于编写高效、结构良好的程序，包括顺序、选择、迭代、数组和文件处理，并在时间压力下保证逻辑无误。
5. Removal of Pre-release Material: A Defining Change | 取消预发布材料：一个决定性变化
One of the most significant structural changes for 2026 candidates is the permanent elimination of the pre-release scenario booklet that previously accompanied Paper 2. In past years, students could analyse a complex task weeks in advance. Now, all problem material is unseen, testing genuine computational thinking and the ability to decompose a problem on the spot. This raises the demand for regular coding practice throughout Year 11, including timed exercises that simulate exam pressure.
对2026年考生来说，最重要的结构性变化之一是永久取消了以往与试卷2配套的预发布情境手册。过去，学生可以提前数周分析一项复杂任务。现在，所有问题材料都是未公开的，测试真正的计算思维和现场分解问题的能力。这提高了在整个Year 11进行定期编码练习的要求，包括模拟考试压力的限时练习。
6. Newly Strengthened Topics: AI, Cybersecurity, and Data Ethics | 新加强的主题：人工智能、网络安全与数据伦理
While artificial intelligence has been lightly touched on in earlier syllabuses, the current framework dedicates a full section to automated and emerging technologies. Candidates must describe how AI and expert systems function, discuss the social and ethical risks of automated decision-making, and evaluate cybersecurity measures such as malware protection and digital signatures. These areas often appear in high-mark essay-style questions on Paper 1, rewarding clear argumentation supported by concrete examples.
尽管早期大纲轻微涉及人工智能，但当前框架将自动化与新兴技术作为一个完整章节。考生必须描述人工智能和专家系统如何工作，讨论自动化决策的社会和伦理风险，并评估恶意软件防护和数字签名等网络安全措施。这些领域经常出现在试卷1的高分论述题中，奖励有具体实例支持的清晰论证。
7. Programming Language Choice: Python, Java, or C#? | 编程语言选择：Python、Java还是C#？
Schools can freely choose the language for teaching and examination, but Python has emerged as the dominant choice due to its readability and simpler syntax, which reduces the risk of trivial syntax errors. However, questions are designed to be language-neutral. What matters is not the language but the soundness of the algorithm. Students are advised to stick to one language and master its standard libraries for string handling, list operations, and file I/O, rather than switching between languages.
学校可以自由选择教学和考试用的语言，但Python因其可读性强和语法简单已成为主要选择，这降低了繁琐语法错误的风险。然而，题目的设计是语言中立的。关键在于算法的合理性而非语言本身。建议学生坚持使用一种语言，并掌握其字符串处理、列表操作和文件输入输出的标准库，而不是在不同语言之间切换。
8. Question Styles and Command Words in 2026 | 2026年的题型和指令词
Examiners are increasingly using higher-order command words such as 'evaluate', 'discuss', and 'justify' even in Paper 2. For example, a programming question may ask you to explain why a particular data structure is more efficient, combining coding with theoretical justification. On Paper 1, compare-type questions are frequently paired with scenarios, requiring explanations of trade-offs between cloud storage and local storage, or between ethical and commercial drivers of technology.
考官越来越多地使用“评估”、“讨论”和“证明合理性”等高阶指令词，甚至在试卷2中也是如此。例如，一道编程题可能要求你解释为什么某种数据结构更高效，将编码与理论论证相结合。在试卷1中，比较型题目经常与情景配对，要求解释云存储与本地存储之间的权衡，或技术的伦理驱动因素与商业驱动因素之间的取舍。
9. Grade Threshold Trends and What They Signal | 分数线趋势及其预示
After the pandemic grading adjustments, Cambridge has returned to typical grade thresholds, but for Computer Science, the raw marks required for top grades remain relatively high compared to other IGCSEs. In 2023 and 2024, an A* typically required around 80% of the total uniform mark, with small variations. With the syllabus now stable, grade boundaries in 2026 are expected to reflect sustained high performance, so every mark in the structured programming questions and the last parts of Paper 1 matters.
在疫情评分调整之后，剑桥已回归典型的分数线，但对于计算机科学来说，与其他IGCSE科目相比，取得高分所需的原始分数仍然相对较高。在2023和2024年，A*通常需要统一分的大约80%，略有波动。随着大纲现已稳定，预计2026年的等级分数线将反映持续的高分表现，因此结构化编程题和试卷1最后几部分的每一分都很重要。
10. Preparing Strategically for the 2026 Exam | 为2026年考试进行策略性备考
A consistent study pattern blending theory and practice yields the best results. Start by creating concise revision notes for each syllabus section, using mind maps for topics like data transmission and logic circuits. Allocate at least two sessions per week to write full Python programs under timed conditions, focusing on past Paper 2 questions without the pre-release. Additionally, practise explaining algorithms using pseudocode and flowcharts, as these are still assessed in the problem-solving section.
将理论与实践融为一体的持续学习模式会取得最好的效果。首先为大纲的每个部分创建简洁的复习笔记，对数据传输和逻辑电路等主题使用思维导图。每周至少安排两次在限时条件下编写完整的Python程序，专注于没有预发布材料的历年试卷2题目。此外，练习使用伪代码和流程图解释算法，因为问题解决部分仍会考核这些内容。
11. The Shift Towards Computational Thinking and Independent Coding | 向计算思维与独立编码的转变
The 2026 exam continues the philosophy that computer science is not merely about memorising facts but about thinking logically and abstractly. Tasks on Paper 2 require decomposition, pattern recognition, and generalisation. Teachers and examiners expect students to debug their code mentally and trace variable values. This shift means that simply learning syntax is insufficient; candidates must cultivate a mindset that breaks down large problems into manageable functions and uses thorough testing.
2026年考试延续了这样一种理念：计算机科学不仅仅关乎记忆事实，更关乎逻辑与抽象思维。试卷2的任务要求进行问题分解、模式识别和泛化。教师和考官期望学生能在脑内调试代码并追踪变量值。这一转变意味着仅仅学习语法是不够的；考生必须培养一种思维模式，将大问题分解为可管理的函数，并进行彻底的测试。
12. Future Trends: Digital Assessment and Evolving Content | 未来趋势：数字化评估与内容演变
Although 2026 remains a traditional pen-and-paper examination, Cambridge has signalled an interest in on-screen assessments for programming papers in the long term. Pilots for on-screen coding are ongoing, and future syllabuses may incorporate automated code testing. Meanwhile, topics such as quantum computing fundamentals and the social impact of large language models are likely to appear in revised specifications. Staying curious about developments beyond the current syllabus can give students an edge in high-band questions that require wider technological awareness.
虽然2026年仍为传统的纸笔考试，但剑桥已表明有意在长远推行编程考试的上机评估。屏幕编程的试点正在进行中，未来的大纲可能会加入自动代码测试。与此同时，量子计算基础和大语言模型的社会影响等主题很可能会出现在修订版规范中。对现有大纲之外的发展保持好奇心，可以在需要更广泛技术意识的高分段题目中为学生带来优势。
