Knowing these details allows you to allocate revision time proportionally. For instance, Unit 1 and Unit 3 carry the most weight, so they deserve more weekly hours.
了解这些细节后，你可以按比例分配复习时间。例如，单元 1 和单元 3 权重最高，值得安排更多周学时。
2. Creating a Long-Term Revision Timetable | 制定长期复习时间表
Begin your structured revision at least 4-6 months before the first written exam. Draw a weekly template and block out sessions of 45-60 minutes each, targeting different units across the week. Aim for 12-15 hours of focused study per week, adjusting as the exam approaches.
至少在首次笔试前 4-6 个月开始有序复习。绘制一个每周模板，每次安排 45-60 分钟的学习时段，在一周内轮换不同单元。目标是每周 12-15 小时的专注学习，随考试临近灵活调整。
Map the entire calendar, marking exam dates, school holidays, and deadlines for Unit 5 coursework. Plan to finish the first pass of all content 8 weeks before exams, leaving the remaining time for intensive practice.
在日历上标出全部日期，注明考试日、学校假期和单元 5 课程项目截止日期。计划在考前 8 周完成所有内容的第一轮复习，余下时间用于密集训练。
3. Phase-Based Revision Strategy | 分阶段复习策略
Phase 1 – Foundation (Weeks 1-8): Go through each specification point systematically. Create concise notes, flash cards, and mind maps for theory-heavy units 1 and 4. For programming, revise syntax, common algorithms, and trace tables.
第一阶段——基础（第 1-8 周）：系统梳理每个大纲要点。为理论密集的单元 1 和单元 4 制作简洁笔记、闪卡和思维导图。编程方面，复习语法、常见算法和追踪表。
Phase 2 – Application (Weeks 9-14): Start attempting topical past paper questions and on-screen coding challenges. Use WJEC mark schemes to understand what examiners expect. Integrate coursework writing and testing for Unit 5 with your daily plan.
第二阶段——应用（第 9-14 周）：开始尝试按主题分类的历年真题和上机编程挑战。利用 WJEC 评分标准了解考官期望。将单元 5 的项目文档编写与测试整合到每日计划中。
Phase 3 – Simulation (Weeks 15-20): Complete full past papers under timed conditions. Mimic the real exam environment, then review every mistake. Gradually reduce new content revision and focus on consolidation and speed.
第三阶段——模拟（第 15-20 周）：在限时条件下完成全套历年试卷。模拟真实考试环境，然后分析每个错误。逐步减少新内容复习，专注于巩固和提升速度。
4. Mastering Theory Units (Unit 1 & Unit 4) | 掌握理论单元（单元 1 与单元 4）
Unit 1 and Unit 4 are content-rich papers demanding precise technical knowledge. Key topics in Unit 1 include data structures, algorithms, logic gates, Boolean algebra, and system software. Unit 4 spans processor architecture, networking, database design, and ethical issues.
单元 1 和单元 4 是内容丰富的笔试，要求精确的技术知识。单元 1 的关键主题包括数据结构、算法、逻辑门、布尔代数和系统软件。单元 4 涵盖处理器体系结构、网络、数据库设计和伦理问题。
Use active recall by covering your notes and writing down everything you remember about a topic. Then check against the specification. Create comparison tables, e.g., sorting algorithm complexities, to see patterns. For networking, draw and label diagrams repeatedly until they become second nature.
使用主动回忆法，盖住笔记，写下你记得的关于某个主题的所有内容，然后对照大纲检查。制作对比表，如排序算法复杂度，以发现规律。对于网络，反复绘制并标注图表，直到成为本能。
5. Programming and Problem-Solving (Unit 2 & Unit 3) | 编程与问题解决（单元 2 与单元 3）
Unit 2 is a practical on-screen exam where you write, test, and debug code in a high-level language (typically Python). Practise with past on-screen assessments and time yourself strictly. Focus on reading problem statements carefully and breaking them into sub-problems.
单元 2 是上机实践考试，要求使用高级语言（通常为 Python）编写、测试和调试代码。用历年上机评估练习，并严格计时。重点在于仔细阅读问题描述并将其分解为子问题。
Unit 3 extends programming with object-oriented concepts, recursion, linked lists, stacks, queues, and advanced algorithms. Implement these data structures from scratch to understand how they work internally. Write code that handles edge cases and passes your own test data.
单元 3 扩展了编程知识，涵盖面向对象概念、递归、链表、栈、队列和高级算法。从零实现这些数据结构以理解其内部工作原理。编写能处理边界情况并通过自建测试数据的代码。
Allocate at least 30% of your weekly revision time to hands-on coding. Even short daily sessions of 20-30 minutes help maintain fluency.
每周至少分配 30% 的复习时间用于动手编码。即使每天 20-30 分钟的短时练习也有助于保持熟练度。
6. Tackling the Non-Exam Assessment (Unit 5) | 攻破非考试评估（单元 5）
The Unit 5 coursework is a substantial project requiring analysis, design, implementation, testing, and evaluation of a programmed solution. Start early: choose a feasible problem and have your teacher approve it well in advance. Create a Gantt chart with milestones for each documentation section.
单元 5 课程项目是一个大型项目，需要对编程解决方案进行分析、设计、实现、测试和评估。尽早开始：选择一个可行的问题，并提前让老师批准。创建甘特图，为每个文档部分设定里程碑。
Integrate project work into your weekly schedule from the very beginning. For example, dedicate Saturday mornings to coding the solution and weekday evenings to writing up design or evaluation. Seek iterative feedback on your written report to ensure it meets WJEC marking criteria.
从复习一开始就将项目工作融入每周计划。例如，周六上午用于编写解决方案代码，工作日晚上用于撰写设计或评估文档。就书面报告寻求迭代反馈，确保符合 WJEC 评分标准。
7. Past Papers and Mark Schemes | 历年真题与评分标准
Past papers are your most powerful revision resource. Download all available papers from the WJEC website, going back to at least 2018. For each paper, simulate exam conditions: no notes, strict timing, and a quiet environment.
历年真题是你最强大的复习资源。从 WJEC 网站下载所有可获得的试卷，至少追溯到 2018 年。对于每份试卷，模拟考试条件：不参考笔记、严格计时、在安静环境中完成。
After finishing, self-mark using the official mark scheme. Pay close attention to how marks are divided among points – often a single mark demands a precise term or a correct line of code. Highlight command words: ‘state’ requires a brief answer, while ‘explain’ needs a cause-and-effect chain.
完成后，使用官方评分标准自评。密切关注分数如何分配——通常一个分数要求一个准确的术语或一行正确代码。圈出指令词：“state” 要求简要回答，而 “explain” 需要因果链。
8. Self-Assessment and Targeted Improvement | 自我评估与针对性提高
After marking several papers, create a personal error log. Categorise mistakes by topic (e.g., binary subtraction, SQL joins, algorithm efficiency) and by type (knowledge gap, misreading question, time pressure). This data-driven approach reveals patterns and prevents plateauing.
批改几份试卷后，建立一个个人错题日志。按主题（例如二进制减法、SQL 连接、算法效率）和错误类型（知识漏洞、误读题目、时间压力）分类。这种数据驱动的方法能揭示规律，避免成绩停滞。
For each weak area, allocate a focused revision block. If you consistently lose marks on trace tables, practise writing out variable states for loops and recursive calls. If SQL questions trip you up, write dozens of queries based on sample schemas until you feel confident.
针对每个薄弱领域，安排一个专注复习时段。如果你在追踪表上反复丢分，就练习写出循环和递归调用的变量状态。如果 SQL 问题难住你，就基于示例模式写几十条查询，直到信心十足。
9. Exam Technique and Time Management | 考试技巧与时间管理
In written papers, always check the marks per question and plan your time accordingly. A 6-mark question should not get the same time as a 1-mark definition. For long-answer questions, spend a minute outlining key points before writing neatly structured paragraphs.
在笔试中，始终检查每题分值并相应规划时间。6 分的问答题不应与 1 分的定义题用时相同。对于长答题，花一分钟列出要点，然后再写出结构清晰的段落。
For the on-screen programming exam, read the entire brief first. Identify the inputs, outputs, and any constraints. Write pseudo-code or comments as a skeleton before coding. Leave at least 10 minutes at the end for testing with a range of data, including boundary cases.
对于上机编程考试，先通读整个题目概要。识别输入、输出和任何约束条件。在编码前，用伪代码或注释搭建骨架。最后至少留出 10 分钟用一系列数据（包括边界情况）进行测试。
10. Final Month Countdown and Well-Being | 最后一个月倒计时与身心健康
During the final four weeks, shift your focus to full-length timed mocks and light review of summary sheets. Resist the urge to learn entirely new topics; reinforce what you already know. Schedule mocks for the exact time of day your real exam will take place.
在最后四周，将重点转移到全程计时的模拟考和摘要笔记的轻量复习上。抵制学习全新内容的冲动；巩固已知知识。将模拟考安排在真实考试的同一时间段进行。
Your physical and mental state significantly affects performance. Maintain a consistent sleep schedule, eat nutritious meals, and incorporate short walks or stretching between study blocks. A calm, well-rested mind retrieves information faster than an exhausted one.
你的身心状态对表现影响很大。保持规律睡眠、营养饮食，并在学习间隙进行短暂散步或拉伸。平静而休息充分的大脑比疲惫的大脑能更快地提取信息。
Keep a revision journal to record daily accomplishments and any anxieties. This helps you stay positive and track progress. Remember, thorough preparation builds confidence, and confidence reduces exam stress.
坚持写复习日志，记录每日成就和任何焦虑。这有助于保持积极心态并追踪进展。请记住，充分准备能建立信心，而信心能减少考试压力。
