1. Start with the Syllabus and Assessment Structure | 从考纲与试卷结构开始

Before planning your revision, download the current CAIE IGCSE Engineering syllabus and list every topic, including materials, manufacturing, mechanisms, electronics, structures and energy.

在规划复习前，先下载最新的 CAIE IGCSE 工程考纲，列出所有主题，包括材料、制造工艺、机构、电子、结构与能源。

Check the assessment structure: Paper 1 is the main theory paper, while Paper 2 focuses on design and communication; the project is usually completed in school under controlled conditions.

查看试卷结构：Paper 1 是主要理论卷，Paper 2 侧重设计与沟通表达；项目部分通常在校内受控条件下完成。

Use the syllabus tick-list to mark your confidence level as red, amber or green each week.

每周用考纲清单把各主题标记为红、黄、绿三种信心等级。

2. Build a 12-Week Reverse Plan | 制定 12 周倒推计划

An effective plan starts from the exam date and works backwards, dividing the remaining time into three phases: foundation, consolidation and simulation.

有效的计划从考试日期倒推，把剩余时间分为三个阶段：基础、巩固与模拟。

Weeks 1-4: cover all syllabus topics once and make concise notes.

第 1-4 周：通读全部考纲内容并做浓缩笔记。

Weeks 5-8: revise weak areas and practise past questions by topic.

第 5-8 周：专攻薄弱点并分主题训练真题。

Weeks 9-12: complete full timed papers, refine exam technique and make final memory sheets.

第 9-12 周：完整限时刷卷、精练答题技巧并制作最终记忆卡。

Set a weekly target of 4-6 hours for IGCSE Engineering if you have three months left, increasing to 8-10 hours in the final month.

如果还剩三个月，每周设定 4-6 小时用于 IGCSE 工程复习，最后一个月增加到 8-10 小时。

Put fixed slots in your calendar: two shorter sessions on weekdays and one longer past-paper session at the weekend.

在日历上安排固定时间段：工作日两次短时段，周末一次较长的真题训练时段。

3. Prioritise High-Yield Topics | 优先复习高频考点

Analyse recent past papers to identify themes that appear almost every year: material properties and selection, forces and moments, gear and lever calculations, circuit symbols, and manufacturing processes.

分析近年真题，找出几乎每年都考的主题：材料性能与选择、力与力矩、齿轮和杠杆计算、电路符号以及制造工艺。

Give more time to topics that carry high marks in Paper 1, such as mechanical advantage, velocity ratio, efficiency, stress and strain, and electrical rules like Ohm’s law and power calculations.

给 Paper 1 中分值高的主题更多时间，如机械效益、速度比、效率、应力与应变，以及欧姆定律和功率计算等电学规则。

MA = Load ÷ Effort; VR = Distance moved by effort ÷ Distance moved by load; Efficiency = (MA ÷ VR) × 100%

Do not skip safety, quality control and sustainability because they are common in both theory and project evaluation questions.

不要忽略安全、质量控制与可持续性，因为它们在理论题和项目评价题中都很常见。

4. Use Active Recall and Spaced Repetition | 使用主动回忆与间隔重复

Reading notes is passive and gives a false sense of mastery; instead close the book and write definitions, formulas and process steps from memory.

阅读笔记是被动学习，容易造成虚假的掌握感；相反，合上书后凭记忆写出定义、公式和工艺步骤。

Convert key facts into flashcards: one side with a prompt such as Define yield strength, the other with the answer and a simple sketch.

把关键知识点做成抽认卡：正面写“定义屈服强度”，背面写答案和简单草图。

Review cards at increasing intervals – 1 day, 3 days, 7 days, 14 days – so information moves into long-term memory.

按逐渐拉长的间隔复习卡片——1 天、3 天、7 天、14 天——让信息进入长期记忆。

Use past-paper questions as a self-test: attempt the question before checking the mark scheme, then write the missing marking points in a different colour.

用真题进行自测：先作答再看评分标准，然后用不同颜色补上遗漏的得分点。

---

5. Practise Past Papers under Timed Conditions | 限时刷真题训练

Start by doing one untimed past paper to learn the format, then gradually introduce the real time limit.

先不限时做一套真题熟悉题型，然后逐步加入真实时间限制。

For Paper 1, divide the total marks by the available minutes so you know how long to spend on each mark; for example, about one minute per mark in a 100-mark paper of 105 minutes.

对于 Paper 1，用总分除以可用分钟数，就知道每分值该花多少时间；例如 100 分、105 分钟的试卷约每分 1 分钟。

Mark your own answers strictly against the official mark scheme: the difference between a good answer and a full-mark answer often lies in stating units, assumptions and final rounding.

严格按照官方评分标准给自己判分：好答案与满分答案的差距往往在于单位、假设和最终取整。

Keep an error log with three columns: question, mistake type, correct approach; review it 48 hours after each paper.

建立错题本，三栏分别为：题目、错误类型、正确思路；每套卷做完 48 小时后重新查看。

---

6. Master Command Words in Paper 1 | 掌握理论卷指令词

CAIE questions use command words to tell you exactly how much detail is needed: state requires a short answer, describe requires a sequence or characteristics, explain requires reasons, and evaluate requires judgement.

CAIE 题目使用指令词说明所需细节程度：state 要求简短回答，describe
