Create a simple checklist for each sub-topic such as ‘stress-strain calculations’, ‘Boolean algebra’, ‘CNC programming’ and ‘engineering materials testing’. Tick off items as you review them. This visual progress tracker boosts motivation and reveals areas that need more depth.
把每个子主题（如应力-应变计算、布尔代数、数控编程、工程材料测试）做成一份清单，复习完一项就勾掉一项。这种可视化的进度追踪既能增强成就感，也能暴露还需要深挖的薄弱环节。
2. Build a Realistic Revision Timetable | 制定切实可行的复习时间表
Divide the winter break into three blocks: Days 1–5 for content refresh, Days 6–10 for deep-dive problem solving, and Days 11–14 for timed past papers. Allocate two 90-minute sessions each morning and one lighter review session in the afternoon. Incorporate breaks for exercise and relaxation to sustain mental energy.
把寒假划分为三个阶段：前五天进行内容重温，中间五天集中攻克难题，最后四天限时刷真题。每天上午安排两个 90 分钟的学习段，下午安排一个较为轻松的回顾段。务必穿插运动与休息，维持大脑的良好运转。
| Block | Focus | Activities |
|---|---|---|
| Days 1–5 | Content refresh | Summarise notes, create flashcards, watch WJEC-specific videos |
| Days 6–10 | Deep-dive practice | Work through past-paper questions, design scenarios, calculation drills |
| Days 11–14 | Exam simulation | Full timed papers under exam conditions, review mark schemes |
每日计划建议如上表，第一天先明确每个阶段的核心任务，再细化到每小时的安排。
3. Reinforce Engineering Mathematics | 巩固工程数学基础
WJEC Engineering requires confident handling of algebra, trigonometry, calculus and statistical process control. Dedicate time to solving simultaneous equations, manipulating vectors and differentiating or integrating simple functions that model velocity, acceleration and displacement. Equations for tensile stress σ = F/A and strain ε = ΔL/L₀ must become second nature.
WJEC 工程数学部分要求熟练运用代数、三角学、微积分和统计过程控制。重点练习联立方程求解、矢量运算，以及对速度和位移建模时的简单微分与积分。拉应力公式 σ = F/A 和应变公式 ε = ΔL/L₀ 必须烂熟于心。
Practise converting units and using standard form, because WJEC mark schemes penalise sloppy arithmetic. Work through problems involving Young’s modulus E = σ/ε and factor of safety calculations. Use flashcards to memorise electrical equations such as P = IV, V = IR and R = ρL/A.

Use real-world examples like aircraft wing composites or bridge cables to connect theory to application.
复习退火、淬火和回火等热处理工艺，并理解它们如何改变晶粒结构。解释合金元素对钢的影响，例如铬赋予不锈钢耐蚀性。用飞机机翼复合材料或桥梁缆索等实例，将理论与实际应用挂钩，更容易在考试中写出高分答案。
5. Solidify Mechanics and Structural Analysis | 夯实力学与结构分析
Be able to resolve forces, draw free-body diagrams and apply conditions for equilibrium: ΣF = 0 and ΣM = 0. Practise calculating reactions, shear forces and bending moments in simply supported beams. WJEC often includes problems with uniformly distributed loads and point loads — sketch diagrams before solving.
务必能分解力、画受力图并运用平衡条件 ΣF = 0 和 ΣM = 0。反复练习简支梁的反力、剪力和弯矩计算。WJEC 常考均布荷载与集中荷载组合，动笔前先画出受力示意图能大幅减少失误。
Link concepts to real structures, such as analysing trusses using method of joints or sections. Understand the terms strut, tie and pin-jointed frame. Revise the principle of moments, centre of gravity and stability, especially for tipping and sliding problems that appear in Unit 3.
把抽象概念与实际结构联系起来，如用节点法或截面法分析桁架。明确撑杆、拉杆和铰接框架的定义。复习力矩原理、重心与稳定性，尤其要掌握 Unit 3 中常见的倾覆与滑动问题。
6. Tackle Electrical and Electronic Systems | 攻克电气与电子系统
Revise DC circuit analysis thoroughly: series and parallel resistors, Kirchhoff’s voltage and current laws, and the superposition theorem. Practise calculating power dissipated in components and the efficiency of motors or transformers. Understand how to use a multimeter and oscilloscope to measure voltage, current and frequency.
彻底重温直流电路分析：串并联电阻、基尔霍夫电压与电流定律以及叠加定理。练习元件功耗计算和电机或变压器的效率。掌握万用表和示波器的使用方法，能测量电压、电流与频率。
Study logic gates, Boolean expression simplification and truth tables. WJEC often asks you to design a simple control circuit using AND, OR, NAND or NOR gates. Practise converting between Boolean algebra, ladder logic and block diagrams. Apply Karnaugh maps where appropriate to minimise logic expressions.
学习逻辑门、布尔表达式化简和真值表。WJEC 经常要求用 AND、OR、NAND 或 NOR 门设计简单的控制电路。练习在布尔代数、梯形图和方框图之间转换。适当运用卡诺图来化简逻辑表达式，这是解答系统设计题的关键技能。
7. Review Manufacturing Processes and CNC | 复习制造工艺与数控技术
Focus on machining (turning, milling, drilling), forming (casting, forging, extrusion) and joining (welding, brazing, adhesive bonding). For each process, be able to describe the equipment, tooling, advantages, limitations and typical tolerances. WJEC values precise technical vocabulary — use terms like ‘feed rate’, ‘depth of cut’ and ‘surface finish’.

WJEC 工程将制造与质量保证紧密结合。复习统计过程控制图（x̄ 图和 R 图）、工序能力指数 Cp 和 Cpk，以及“公差累积”的含义。要能判读控制图，并在工序失控时提出纠正措施。
For the design project, revisit project life cycle stages: specification, feasibility study, design, prototype, test and evaluation. Learn how Gantt charts, critical path analysis and resource histograms are used for planning. Practise writing concise technical reports that follow WJEC’s format requirements.
针对设计项目，重温项目生命周期：规格说明、可行性研究、设计、样机制造、测试与评估。掌握甘特图、关键路径分析和资源直方图的规划方法。练习按照 WJEC 格式要求撰写精炼的技术报告，这直接影响 Unit 4 的得分。
9. Intensive Past-Paper Practice | 高强度真题演练
Collect WJEC past papers from the last five sessions and work through them in timed conditions. Begin with open-book sessions if needed, but quickly transition to fully closed-book exams. After each paper, use the official mark scheme to self-assess — note where marks are lost for missing units, insufficient justification or sloppy diagrams.
收集过去五年的 WJEC 真题，严格限时完成。初期可以开卷辅助，但必须尽快过渡到完全闭卷的模拟考试。每做完一套，就对着官方评分方案自行批改，特别留意因漏写单位、论证不足或示意图潦草而丢分的地方。
Keep an error log with four columns: topic, mistake, correct approach and a model answer snippet. Review this log every three days. Over the winter break, you should aim to complete at least four full Unit 3 papers and two Unit 4 project-style tasks.
准备一个错题记录表，包含四栏：主题、错误之处、正确解法和标准答案片段，每隔三天复习一次。寒假期间至少完成四套完整的 Unit 3 试卷和两项 Unit 4 项目式任务，才能形成扎实的实战能力。
10. Revisit Your Laboratory Notebooks and Project | 重温实验日志与设计项目
WJEC’s Unit 4 requires you to submit a substantial portfolio. Use the holiday to re-evaluate your experimental data, improve analysis graphs and strengthen the evaluation section. Ensure you have clearly recorded risk assessments, calibration records and raw data tables as required by the mark scheme.
WJEC 的 Unit 4 要求提交一份项目作品集。利用假期重新审视实验数据，优化分析图表并充实评估部分。务必确认风险评价、仪器校准记录和原始数据表格都按评分标准的要求清晰呈现。
For the design project, re-read the client brief and check that your proposed solution meets all specifications. Refine CAD models or circuit simulations. Prepare for the final oral assessment by drafting bullet-point answers to potential questions about your design choices and testing outcomes.
重新阅读设计任务书，检查你提出的方案是否满足所有要求。优化 CAD 模型或电路仿真，并针对最终口头答辩撰写要点式回答，内容涵盖设计决策和测试结果——这将极大增强你临场表达的信心。
11. Form a Peer Study Group and Use Digital Resources | 组建学习小组并善用数字资源
Connect with classmates via video call to explain challenging topics to each other. Teaching a peer is one of the most effective ways to deepen your own understanding. Share flashcards, quiz each other on material properties or circuit analysis, and collaboratively work through difficult past-paper questions.
通过视频通话与同学组建学习小组，互相讲解难题。教别人的过程会显著加深你自己的理解。共享记忆卡片，互相测试材料特性或电路分析，并合作攻克历年真题中的高难度题目。
Supplement revision with high-quality WJEC-specific resources such as revision guides, interactive simulations for logic circuits, and instructional videos on welding or CNC machining. Be selective and avoid passive watching — pause frequently to predict explanations or solve embedded problems.
辅以高质量的 WJEC 专项资源，如复习指南、逻辑电路互动仿真以及焊接或数控加工的教学视频。避免被动观看，经常暂停视频，先尝试预测解释或求解内置习题，这样做才能让视频学习真正有效。
12. Maintain Wellbeing and Exam Readiness | 保持身心健康与应试状态
Sustained revision only works when paired with adequate sleep, regular physical activity and proper nutrition. Set a fixed bedtime and avoid screens 30 minutes before sleep. A 20-minute walk or quick workout between study blocks improves blood flow to the brain and sharpens focus for the next session.
持续高效的复习离不开充足睡眠、规律运动和合理饮食。设定固定的就寝时间，并在睡前 30 分钟远离屏幕。学习段之间安排 20 分钟散步或简短锻炼，能促进大脑供血，让你在下一阶段保持高度专注。
In the final days of the holiday, simulate the real exam morning: wake up early, eat a balanced breakfast and sit a complete paper exactly at the time your WJEC exam will take place. This rehearsal eliminates anxiety and trains your body clock to perform optimally under exam conditions.
假期的最后几天，模拟真实的考试早晨：早起、吃均衡的早餐，并在 WJEC 考试的实际时间段完整地做一套试卷。这种预演能消除临场紧张，让生物钟适应考试节奏，帮助你发挥出最佳水平。
