1. Overview of CIE GCSE Physics | 考试概述
CIE GCSE Physics (0625) is an internationally recognised qualification designed for students aged 14–16. It develops a solid understanding of physical principles through a blend of theoretical knowledge and practical investigation. The course places emphasis on applying concepts to everyday situations and on the development of scientific inquiry skills.
CIE GCSE 物理（课程代码 0625）是为 14 至 16 岁学生设计的国际公认资格证书。课程通过理论知识与实验探究相结合的方式，培养学生的物理基础素养，注重将概念应用于日常生活情景，并发展科学探究能力。
The syllabus is examined at the end of the two-year course, and students can be entered for either the Core tier or the Extended tier, giving flexibility according to ability. All candidates must complete practical work throughout the course, as experimental skills are assessed in the written papers.
该课程在两年学习结束后进行统考，学生可根据自身能力选择核心或拓展层级报考，具有灵活性。所有考生都必须在课程学习中完成实验活动，因为实验技能会在笔试中直接考查。
2. Assessment Objectives | 评估目标
The examination papers are designed around three main Assessment Objectives (AOs). AO1 targets knowledge and understanding of scientific phenomena, facts, laws, definitions, and theories. You will need to recall and apply physical principles accurately.
考试卷围绕三大评估目标设计。AO1 考查对科学现象、事实、定律、定义和理论的认知与理解。你需要准确回忆并应用物理原理。
AO2 focuses on handling information and problem-solving. This involves interpreting data from graphs, tables, and diagrams, as well as carrying out calculations and drawing conclusions. Finally, AO3 evaluates experimental skills and investigation techniques, such as planning an experiment, identifying variables, and assessing safety precautions. Around 20% of the marks are linked to practical skills.
AO2 侧重于信息处理与问题解决能力，包括解读图表、表格和示意图中的数据，进行计算并得出结论。AO3 则评估实验技能与探究方法，例如设计实验、识别变量、评估安全措施等。约 20% 的分数与实验技能相关。
3. Core and Extended Tiers | 核心与拓展层级
CIE IGCSE Physics offers two tiers of entry: Core and Extended. The Core tier targets grades C to G and covers the basic material in each topic. It is suitable for students who find the subject challenging or who do not require higher grades.
CIE IGCSE 物理提供两种报考层级：核心层与拓展层。核心层目标成绩为 C 至 G，涵盖每个主题的基础内容，适合学习有困难或不需要更高等级的学生。
The Extended tier encompasses the Core content plus additional, more challenging concepts, allowing access to grades A* to C. Top-performing candidates aiming for A* must be thoroughly familiar with the Extended supplement topics, such as the transformer equation, advanced momentum problems, and more detailed radiation physics. Your teacher will decide which tier best suits your progress.
拓展层包含核心内容以及更深、更具挑战性的补充概念，成绩可达 A* 至 C。目标是 A* 的高分考生必须熟练掌握拓展补充主题，如变压器公式、较复杂的动量问题以及更深入的辐射物理。你的老师会根据你的学习进度决定报考层级。
4. Examination Paper Structure | 试卷结构
All candidates sit three papers. For the Core tier, you will take Paper 1 (Multiple Choice, 40 questions, 45 minutes), Paper 3 (Theory, short-answer and structured questions, 1 hour 15 minutes), and either Paper 5 (Practical Test) or Paper 6 (Alternative to Practical). For the Extended tier, the combination is Paper 2 (Multiple Choice, 40 questions, 45 minutes), Paper 4 (Theory, structured questions, 1 hour 15 minutes), and a practical paper.
所有考生需参加三份试卷。核心层考生需参加 Paper 1（选择题，40 题，45 分钟）、Paper 3（简答与结构化理论题，1 小时 15 分钟）以及 Paper 5（实验操作考试）或 Paper 6（实验笔试替代）。拓展层考生则组合为 Paper 2（选择题，40 题，45 分钟）、Paper 4（结构化理论题，1 小时 15 分钟）和一份实验卷。
The weightings are significant: the Multiple Choice paper contributes 30%, the Theory paper 50%, and the Practical paper 20% to the final grade. The Practical Test requires direct experimentation in a lab, while the Alternative to Practical is a written paper assessing experimental design and data analysis. Both assess the same skills.
分值权重很关键：选择题卷占最终成绩的 30%，理论卷占 50%，实验卷占 20%。实验操作考试要求在实验室现场操作，而实验笔试替代卷则以书面形式考查实验设计与数据分析。两种形式评估的是相同的技能。
5. Topic: General Physics | 主题：普通物理
General Physics covers the mechanics of motion and forces. You will study concepts such as speed, velocity, acceleration, mass, weight, density, and the effects of forces. Key equations include v = u + at, s = ut + ½at², and F = ma. Understanding graphs of distance–time and speed–time is essential, and you must be able to calculate gradients and areas under curves.

Thermal expansion is covered in everyday contexts, such as thermometers and bimetallic strips. The topic then develops into heat transfer: conduction, convection, and radiation. You need to describe experiments demonstrating these processes and apply them to real-world examples, including vacuum flasks. The concept of specific heat capacity (E = mcΔθ) and latent heat (E = mL) is vital for calculations and is part of the Extended tier.

Magnetism and electromagnetism are linked through the magnetic effect of a current. You will learn about solenoids, electromagnets, and the motor effect. The left-hand rule for forces on a current-carrying conductor is essential. Electromagnetic induction, generators, transformers, and the transformer equation (Vₚ/Vₛ = Nₚ/Nₛ) appear in the Extended tier, often in the context of power transmission. Logic gates and their truth tables are also part of the specification, with basic digital electronics knowledge assessed.

For the Extended tier, you will study nuclear fission, fusion, and the mass–energy equivalence, with an understanding of the conditions needed for both processes.
该主题还包括背景辐射、探测方法（盖革-米勒管、云室）、半衰期计算以及放射性同位素在工业和医学中的应用。涉及放射源的安全防护措施会被强调。拓展层要求学习核裂变、核聚变以及质能等价关系，并理解这两种过程所需的条件。
10. Practical Skills and Investigations | 实验技能与探究
Practical work is not a separate topic but an integrated skill assessed across all written papers. You are expected to know common laboratory apparatus, techniques for measuring length, time, temperature, current, and volume, and methods for reducing errors and improving accuracy. Tables of results and graphs must be plotted with appropriate scales, axes labels, and units.
实验操作并非独立主题，而是贯穿所有笔试卷的综合技能。你需要认识常用实验器材，掌握测量长度、时间、温度、电流和体积的技术，以及减少误差、提高精度的方法。记录表格和图表绘制时，必须选用合适标度、轴标签和单位。
Questions often ask you to identify independent, dependent, and control variables, to suggest how to conduct a fair test, or to describe a complete experimental setup for a given investigation. You should be able to handle anomalous data and draw a best-fit line. Planning a simple investigation, including a risk assessment, is a frequently examined skill. Revising required practicals from the syllabus will significantly boost your confidence.
考题常要求你识别自变量、因变量和控制变量，建议如何进行公平测试，或针对给定探究描述完整的实验设置。你需要能处理异常数据并画出最佳拟合线。设计简单探究方案，包括风险评估，是常考技能。复习大纲列出的必做实验将极大提升你的应试信心。
11. Key Formulas and Data | 重要公式与数据
Throughout the exam, you will receive a formula sheet, but being familiar with the symbols and how to apply each equation is crucial. The core formulas you must be able to use include:
考试中你会得到公式表，但熟悉符号含义并会应用每个方程至关重要。你必须会使用的核心公式包括：
| Quantity | Equation |
|---|---|
| Speed | v = s / t |
| Acceleration | a = (v – u) / t |
| Force | F = ma |
| Weight | W = mg |
| Density | ρ = m / V |
| Work done | W = Fd |
| Kinetic energy | KE = ½mv² |
| GPE | PE = mgh |
| Power | P = W / t |
| Pressure | p = F / A |
Additionally, you must recall constants such as the speed of light in a vacuum (3.0 × 10⁸ m/s) and the acceleration of free fall, g ≈ 9.8 m/s². The data sheet also provides electrical symbols and the periodic table for some atomic physics questions.
此外，你需要记住一些常量，如真空中光速（3.0 × 10⁸ m/s）和重力加速度 g ≈ 9.8 m/s²。数据表还提供电路符号，并在部分原子物理题中提供元素周期表。
12. Tips for Success | 成功备考建议
Start your revision by printing a copy of the syllabus and ticking off topics as you review them. Focus on the command words in questions—such as ‘state’, ‘describe’, ‘explain’, and ‘calculate’—and give answers at the appropriate level of detail. Practice past papers under timed conditions and mark them using the official scheme, noting where marks are awarded.
开始复习时，打印一份大纲，每复习完一个主题就打勾标记。重点关注题干中的指令词，如“陈述”、“描述”、“解释”和“计算”，并根据要求给出合适详略的回答。在限时条件下练习历年真题，并对照官方评分方案批改，注意给分点在哪里。
Make summary notes that link concepts together, and draw clearly labelled diagrams. In practical-based questions, always mention safety and reliability of results. Revision that interleaves topics, instead of cramming them one by one, is proven to improve retention. Finally, ensure you understand unit conversions and significant figures, as these are commonly penalised in calculations.
制作连接概念的总结笔记，并绘制标注清晰的示意图。在实验类题目中，始终提及安全和结果的可靠性。交替穿插式复习比逐章节突击记忆更能提高知识留存率。最后，务必掌握单位换算和有效数字的使用，因为计算题中常在这一点上扣分。
