2. Content Additions: AI, Cybersecurity & Law | 新增内容：人工智能、网络安全与法律
New content areas have been introduced to keep pace with the digital landscape. Students will now study the fundamentals of AI, including simple expert systems, supervised vs unsupervised learning concepts, and the societal impact of automation. Cybersecurity takes centre stage with deeper coverage of encryption, public-key infrastructure, penetration testing, and case studies on data breaches.
为紧跟数字时代，大纲引入了新的内容领域。学生将学习人工智能的基础知识，包括简单的专家系统、有监督与无监督学习概念，以及自动化对社会的影响。网络安全成为重点，深度涉及加密、公钥基础设施、渗透测试以及数据泄露案例分析。
Additionally, the legal and ethical framework surrounding computing has been expanded. Topics like the General Data Protection Regulation (GDPR), Computer Misuse Act amendments, and ethical considerations in algorithm design now feature more prominently, encouraging students to evaluate real-world scenarios critically.
此外，围绕计算的道德法律框架得到扩展。《通用数据保护条例》（GDPR）、《计算机滥用法》修正案以及算法设计中的伦理考量等内容更加突出，鼓励学生批判性地评估现实场景。
3. Topics Reduced or Removed | 删减或弱化的主题
To make room for new content, some legacy topics have been trimmed. Detailed assembly language programming for specific processors has been reduced, replaced by a broader understanding of machine-code principles and the fetch-decode-execute cycle. Older software development methodologies like the waterfall model are now covered more concisely, while agile and DevOps approaches receive greater emphasis.
为了给新内容腾出空间，一些旧主题被压缩。针对特定处理器的详细汇编语言编程被弱化，取而代之的是对机器码原理和取指-解码-执行周期的更广泛理解。像瀑布模型这类较老的软件开发方法现在被更简略地处理，而敏捷和DevOps方法则更受重视。
The study of legacy storage devices and outdated networking standards has also been minimised. Students will instead focus on modern storage technologies (flash, SSDs, cloud) and contemporary protocols such as Wi-Fi 6 and 5G.
对旧式存储设备和过时网络标准的学习也被降至最低。学生将转而关注现代存储技术（闪存、固态硬盘、云）和当代协议，如Wi-Fi 6与5G。
4. Assessment Structure Overhaul | 评估结构改革
The assessment model has been redesigned to enhance fairness and reduce reliance on centre-assessed coursework. The previous non-exam assessment (NEA) programming project has been replaced by a new Component 2: Programming and Algorithms, which is a timed on-screen examination. This change aims to standardise the evaluation of coding skills across all candidates.
评估模型经过重新设计，以提高公平性并减少对中心评估课程作业的依赖。此前的非考试评估（NEA）编程项目已被新的“组件2：编程与算法”取代，这是一个限时的上机考试。这一变化旨在标准化对所有考生编程技能的评估。
Component 1 remains a written paper focusing on computer systems, architecture, data, and theoretical concepts. Component 2 now requires students to write, debug, and test programs in a regulated environment, often using a specified high-level language such as Python. The weighting between components has been adjusted to 50% each for the two exam papers, making practical coding just as important as theory.
组件1仍为笔试，侧重计算机系统、体系结构、数据和理论概念。组件2现在要求学生在受控环境中编写、调试和测试程序，通常使用Python等指定高级语言。两个试卷之间的权重调整为各占50%，使实践编程与理论同等重要。
5. The On-Screen Programming Exam | 上机编程考试
Component 2 will be conducted entirely on a computer with lockdown browser software to prevent unauthorised access to external resources. The paper includes both pre-release material and unseen challenges. Students must demonstrate algorithmic problem solving, file handling, object-oriented design, and the use of appropriate data structures such as arrays, lists, stacks, queues, and trees.
组件2将完全在计算机上进行，使用锁定浏览器软件以防止未经授权访问外部资源。试卷包含预先发放的材料和未知挑战。学生必须展示算法问题解决能力、文件处理、面向对象设计，以及使用数组、列表、栈、队列和树等合适的数据结构。
Mark schemes will reward efficient solutions, correct syntax, and clear comments. Execution time and memory usage may be tested indirectly through questions on algorithm complexity. For instance, you might be asked to compare the time complexity of a linear search versus a binary search using Big O notation, such as O(n) vs O(log n).
评分方案将奖励高效的解决方案、正确的语法和清晰的注释。通过算法复杂度的问题，可能间接测试执行时间和内存使用。例如，你可能需要比较线性搜索和二分查找的时间复杂度，使用大O表示法，如O(n) 对比 O(log n)。
6. Embracing Computational Thinking | 拥抱计算思维
Computational thinking—the ability to break down problems, recognise patterns, abstract details, and design algorithms—is now the backbone of the entire course. Both examination components are designed to assess these skills explicitly. Questions will require you to write pseudocode, trace algorithms, and apply decomposition to unfamiliar contexts.
计算思维——分解问题、识别模式、抽象细节和设计算法的能力——现已成为整个课程的基石。两个考试组件都旨在明确评估这些技能。题目将要求你编写伪代码、跟踪算法，并将分解法应用于陌生情境。
A typical example could involve a pathfinding algorithm on a grid. You might be given a scenario where a robot needs to navigate a 2D array, and you must develop a solution using breadth-first search. Understanding space and time trade-offs is crucial, often expressed as O(n²) for nested iterations or O(n) for a linear scan.
一个典型示例可能涉及网格上的寻路算法。你可能得到一个场景，机器人需要在二维数组上导航，你必须使用广度优先搜索开发解决方案。理解空间与时间的权衡至关重要，通常表示为嵌套迭代的 O(n²) 或线性扫描的 O(n)。
7. Data Representation and Big Data | 数据表示与大数据
The data representation topic has been expanded to include Unicode encodings, floating-point normalisation, and binary operations such as two’s complement for negative numbers. Students must be able to convert between denary, binary, and hexadecimal fluently. For instance, normalising the binary number 101.1₂ to scientific form 1.011₂ × 2² is a skill frequently tested.
数据表示主题已扩展，包括Unicode编码、浮点数规范化以及二进制运算，如负数的二进制补码。学生必须能够熟练地在十进制、二进制和十六进制之间转换。例如，将二进制数 101.1₂ 规范化为科学形式 1.011₂ × 2² 是一项经常被测试的技能。
Big data concepts now appear in the database and ethics sections. You are expected to discuss volume, velocity, variety, and veracity (the four V’s), as well as the use of MapReduce and distributed storage systems like Hadoop. These topics connect directly to practical investigations in the programming exam.
大数据概念现在出现在数据库和伦理部分。你需要讨论数据的容量、速度、多样性和真实性（4V），以及MapReduce和像Hadoop这样的分布式存储系统的使用。这些主题直接与编程考试中的实践探究相关联。
8. Trends in Question Style and Difficulty | 试题风格与难度趋势
Exam questions are shifting towards extended responses and scenario-based application rather than simple recall. You can expect more 6–12 mark questions that require you to analyse a case study, propose a solution, and justify your choices using technical vocabulary. Diagrams such as flowcharts, entity-relationship diagrams, and network topologies must be drawn and interpreted.
考试题目正在转向扩展回答和基于场景的应用，而非简单的记忆。你可以预期更多6-12分的题目，要求你分析案例研究、提出解决方案并运用技术词汇来论证你的选择。必须绘制并解释流程图、实体关系图和网络拓扑等图表。
Trend analysis of past papers suggests a growing emphasis on comparisons: e.g., compare circuit switching and packet switching, or contrast symmetric and asymmetric encryption. The depth of understanding required is higher, meaning rote learning alone will not suffice.
对历年试卷的趋势分析表明，越来越重视比较：例如，比较电路交换与分组交换，或对比对称加密与非对称加密。所需的深度理解程度更高，意味着仅靠死记硬背是不够的。
9. How to Prepare for the 2026 Exams | 如何为2026年考试做好准备
Start by obtaining the new specification and specimen assessment materials from the WJEC website. Familiarise yourself with the on-screen exam environment by using official practice platforms if available. Focus on building a strong foundation in Python or the language specified by your centre, ensuring you can implement linked lists, binary search trees, and sorting algorithms without external libraries.
首先从WJEC网站获取新大纲和样题评估材料。如果有官方练习平台，请熟悉上机考试环境。集中精力为Python或你中心指定的语言打下坚实基础，确保你能够在不依赖外部库的情况下实现链表、二叉搜索树和排序算法。
Regularly practise writing pseudocode and tracing algorithms by hand—these skills are essential for the written paper as well. Create a revision timetable that dedicates equal time to theory topics (system architecture, networking, ethical issues) and practical coding challenges. Join study groups to discuss complex concepts and peer-review each other’s code.
定期练习手写伪代码和跟踪算法——这些技能对笔试同样至关重要。制定复习时间表，为理论主题（系统架构、网络、伦理问题）和实际编程挑战分配同等时间。加入学习小组，讨论复杂概念并相互审查代码。
10. Moving Forward with Confidence | 自信迎接未来
