Check the exam duration and mark allocation. If a design-and-make task is part of the assessment, understand how much time is given for planning versus execution. Knowing the weighting will allow you to devote more revision time to heavily weighted topics.
检查考试时长和分值分配。如果评估中包含设计与制作任务，要了解计划与执行分别给予多长时间。了解权重后，你就可以将更多复习时间分配给占分比重大的主题。
2. Building a Weekly Study Timetable | 制定每周学习时间表
Start by mapping out the weeks before your exam. Dedicate specific days to distinct topics – for example, Monday for materials, Wednesday for electronics, and Friday for safety. Even short, focused sessions of 20–30 minutes can be highly effective if you stay consistent. Avoid last-minute cramming by spreading your revision over several weeks.
先从考前几周开始规划。为不同主题安排固定的学习日——例如周一复习材料，周三复习电子学，周五复习安全。即使每次只有20–30分钟的专注学习，只要坚持就能取得很好效果。避免临时抱佛脚，将复习分散到数周内。
Use a simple table or planner to track your progress. Mark each completed session with a tick – this visual progress motivates you to keep going. Remember to include break days to prevent burnout and allow your brain to process the information.
用简单的表格或计划本来记录进度。每完成一次复习就打勾——这种可视化的进步能激励你继续前进。记得安排休息日，避免过度疲劳，也让大脑有时间消化信息。
3. Prioritising Core Topics: Materials and Their Properties | 优先核心主题：材料及其性能
A significant portion of the WJEC engineering exam focuses on materials. You need to recognise common materials such as mild steel, aluminium, pine, and acrylic, and understand their properties – strength, hardness, flexibility, and conductivity. Create flashcards with the material name on one side and its properties and uses on the other.
WJEC工程考试中相当大一部分内容集中在材料上。你需要认识普通材料，如低碳钢、铝、松木和亚克力，并了解它们的性能——强度、硬度、柔韧性和导电性。制作闪卡，一面写材料名称，另一面写性能与用途。
Be able to classify materials into groups: metals (ferrous and non-ferrous), woods (hardwoods and softwoods), plastics (thermoplastics and thermosets), and composites. Practice linking materials to real-world products – for example, explain why a saucepan is made of metal with a plastic handle. This analytical thinking is often tested.
要能够将材料分类：金属（铁与非铁金属）、木材（硬木与软木）、塑料（热塑性塑料与热固性塑料）和复合材料。练习将材料与现实产品联系起来——例如，解释为什么平底锅用金属制成而把手是塑料的。这种分析思维常常被考查。
4. Mastering Workshop Safety and Risk Assessment | 掌握车间安全与风险评估
Safety is non-negotiable in engineering. Exam questions often ask you to identify hazards, suggest appropriate personal protective equipment (PPE), or describe safe procedures when using tools such as saws, drills, and soldering irons. Memorise the key safety rules and be prepared to write clear, step-by-step safety precautions.
安全在工程中不容忽视。考试题目经常要求你识别危险、建议合适的个人防护装备（PPE），或描述使用锯、钻和焊烙铁等工具时的安全步骤。熟记关键的安全规则，并准备好写下清晰、分步的安全预防措施。
Understand the common hazard symbols and what they indicate – for example, flammable, toxic, corrosive. Practice completing a simple risk assessment for a given workshop task. A useful structure is: identify the hazard, assess the risk, and state the control measures. Always link your answer to specific examples.
理解常见的危险符号及其含义——例如易燃、有毒、腐蚀。练习完成一个给定车间任务的简单风险评估。一个有用的结构是：识别危险、评估风险、陈述控制措施。务必将你的答案与具体例子联系起来。
5. Tools, Measuring and Manufacturing Techniques | 工具、测量与制造技术
You should know the names and uses of basic workshop tools: ruler, tri-square, coping saw, file, pillar drill, and hot glue gun. Be able to select the correct tool for a given job and justify your choice. Measuring accurately and marking out are fundamental engineering skills – practice reading a ruler in millimetres and centimetres.
你应该知道基本车间工具的名称和用途：直尺、直角尺、钢丝锯、锉刀、台钻和热熔胶枪。能够为给定任务选择合适的工具并说明理由。精确测量和划线是基本工程技能——练习以毫米和厘米为单位读取直尺。
Manufacturing processes like cutting, shaping, joining, and finishing are also examined. For each material, you may need to suggest an appropriate manufacturing method. Revise techniques such as using a template for plastics, sanding wood, or crimping wires. Diagrams can help you explain these processes more clearly.
制造工艺，如切割、塑形、连接和表面处理，也会考查。针对每种材料，你可能需要提出合适的制造方法。复习各种技术，比如使用塑料模板、打磨木头或压接电线。简图能帮助你更清晰地解释这些过程。
6. Basic Electronics: Circuits and Components | 基础电子学：电路与元器件
Year 7 WJEC Engineering introduces simple circuits. You need to identify components such as batteries, bulbs, switches, resistors, and LEDs. Understand how to draw and interpret circuit diagrams using standard symbols. Learn the difference between series and parallel circuits and how current flows in each.
WJEC七年级工程会介绍简单电路。你需要识别电池、灯泡、开关、电阻和发光二极管（LED）等元器件。懂得如何用标准符号绘制和解读电路图。了解串联与并联电路的区别，以及电流在每种电路中的流动方式。
Ohm's Law: V = I x R
A key relationship you may encounter is Ohm's Law, where V is voltage, I is current, and R is resistance. Even at Year 7, you might be asked to perform simple calculations. Practice rearranging the formula. Remember to use correct units – volts (V), amperes (A), and ohms (Ω).
你可能会遇到的一个关键关系是欧姆定律，其中V为电压，I为电流，R为电阻。即使在七年级，你也可能会被要求进行简单计算。练习变换公式。记得使用正确的单位——伏特（V）、安培（A）和欧姆（Ω）。
7. Mechanisms: Levers, Gears and Motion | 机构：杠杆、齿轮与运动
Mechanisms allow us to change the type or direction of motion. You should understand the basic lever types (first, second, and third class), and be able to identify the effort, load, and fulcrum. Simple gear trains demonstrate how rotational speed and torque can be modified – a small gear driving a large gear increases torque but reduces speed.
机构使我们能够改变运动类型或方向。你应该了解基本的杠杆类型（第一、第二和第三类），并能够识别用力点、负载点和支点。简单的齿轮传动系显示了如何改变转速和扭矩——小齿轮带动大齿轮会增加扭矩，但降低转速。
Revise common linkages and the types of motion: linear, rotary, reciprocating, and oscillating. Recognise everyday applications, such as a bicycle crank converting rotary motion to linear motion via a chain. Practice sketching simple mechanism diagrams and annotating them with arrows and labels.
复习常见连杆机构及运动类型：直线运动、旋转运动、往复运动和摆动。识别日常应用，例如自行车曲柄通过链条将旋转运动转化为直线运动。练习绘制简单机构简图，并用箭头和标签进行注释。
8. Design Process and Communication | 设计过程与沟通表达
Engineering is about solving problems. You may need to describe the design process: research, brainstorming, developing ideas, modelling, testing, and evaluating. Be ready to sketch a quick product idea and annotate it with materials, dimensions, and key features. Use clear, neat lettering and correct drawing conventions.
工程学就是要解决问题。你可能需要描述设计过程：调研、头脑风暴、发展思路、建模、测试和评估。准备好快速勾勒产品构思，并标注材料、尺寸和关键特征。使用清晰、整洁的字体和正确的绘图规范。
Communication also includes writing a specification and evaluating a product against the specification. Learn to use technical vocabulary: function, aesthetics, ergonomics, sustainability. When practicing, compare two similar products and explain which one meets the design brief better.
沟通表达还包括撰写产品规格说明，以及根据规格对产品进行评估。学会使用技术词汇：功能、美学、人机工程学、可持续性。练习时，比较两种相似的产品，并解释哪一个更符合设计需求。
9. Active Revision Techniques for Engineering | 工程学科主动复习技巧
Passively reading notes is often ineffective. Instead, use active methods: teach a concept to a friend or family member, create mind maps linking topics, and complete quick-quizzes. For engineering, hands-on practice is ideal – if you have access to a simple electronics kit or modelling materials, use them to reinforce theory.
被动地阅读笔记常常效果不佳。相反，采用主动方法：把概念讲给朋友或家人听，绘制联系各个主题的思维导图，并完成快速小测验。对于工程学，动手实践最为理想——如果手头有简单的电子套件或模型材料，就用它们来巩固理论知识。
Try the 'Feynman Technique': explain a topic in simple language as if to a complete beginner. If you struggle, review that area until you can simplify it. Another strategy is to create a revision poster with diagrams and key facts for each topic and display it where you will see it regularly.
尝试“费曼技巧”：用简单的语言向一个完全不懂的人解释一个主题。如遇困难，就回头复习，直到你能简化它。另一个策略是为每个主题制作一张含有简图和关键知识点的复习海报，贴在经常能看到的地方。
10. Practice with Past Papers and Sample Questions | 通过历年真题与样题练习
Once you have covered the core topics, start working through past papers or example questions. Time yourself so you get used to the pace of the exam. After completing a section, mark your answers carefully using the mark scheme – this shows you what examiners are looking for and how to structure high-scoring answers.
完成核心主题的复习后，开始做历年真题或样题。计时做题，让自己适应考试节奏。完成一个部分后，仔细对照评分标准批改——这能让你了解考官想要什么样的答案，以及如何构建高分答案。
Pay attention to command words such as 'state', 'describe', 'explain', and 'evaluate' – each requires a different depth of response. Practice writing full sentences that include technical terminology. If a question asks you to 'explain why stainless steel is used for a kitchen sink', answer with both the material property (corrosion resistance) and the practical reason (easy to clean).
注意指令词，如“陈述”、“描述
