1. Know Your Syllabus and Assessment Structure | 吃透考纲与评分结构

Start with the official CIE 9702 syllabus. Print it and turn it into a checklist. Every learning outcome can become a question. Familiarise yourself with the A2 paper structure: Paper 4 (structured questions, 100 marks, 2 hours) and Paper 5 (Planning, Analysis and Evaluation, 30 marks, 1 hour 15 minutes). Know the weightings: A2 topics make up about half of your total A-Level grade, and Paper 5 tests practical skills through written answers, not bench work.

从 CIE 9702 官方考纲入手。打印出来，把它当作一份清单。每一条学习目标都有可能成为考题。熟悉 A2 的试卷结构：Paper 4（结构化问题，满分 100，时间 2 小时）和 Paper 5（实验规划、分析与评估，满分 30，时间 1 小时 15 分钟）。清楚各卷权重：A2 内容约占 A-Level 总成绩的一半，Paper 5 是以笔试形式考查实验技能，而非动手操作。

Mark topics that are frequently combined in questions, such as circular motion with gravitational fields, or capacitors with exponential decay. When you revise, always refer back to the syllabus to check if you have truly met each requirement.

标记出常被综合考查的知识点，比如圆周运动与引力场结合、电容器与指数衰减结合。复习时一定要不断回看考纲，确认自己是否真的满足了每一条要求。

2. Build Deep Conceptual Understanding | 构建深层概念理解

Don’t just memorise equations. CIE rewards students who can explain physics clearly and apply ideas to unfamiliar situations. For every topic, drill down to the ‘why’. Why does a satellite in a circular orbit accelerate even at constant speed? Because velocity is a vector; direction changes, so velocity changes, hence acceleration exists.

不要只背公式。CIE 考试青睐那些能清晰解释物理现象、并能将概念应用到新颖情境中的考生。对每一个知识点，都要追问“为什么”。为什么绕圆轨道运行的卫星即使速率不变也有加速度？因为速度是矢量，方向改变，速度就改变，因此存在加速度。

Use analogies to strengthen understanding. Gravitational field and electric field share similar forms: g = GM/r² and E = kQ/r². Compare similarities and differences — both follow inverse-square laws, but gravitational force is always attractive while electrostatic force can be attractive or repulsive. This helps you tackle comparison questions in Paper 4.

善用类比加深理解。引力场和电场方程形式相似：g = GM/r² 和 E = kQ/r²。比较它们的异同——都遵循平方反比律，但引力永远是吸引力，而静电力可以是吸引力或排斥力。这种联系有助于应对 Paper 4 中的比较类问题。

For quantum physics, connect the photoelectric effect equation hf = Φ + KE_max (where hf is photon energy, Φ is work function) to the idea of one-to-one photon-electron interaction. Understanding the particle model prevents you from common mistakes like assuming brighter light increases kinetic energy.

在量子物理部分，要把光电效应方程 hf = Φ + KE_max（hf 为光子能量，Φ 为逸出功）与光子-电子一对一相互作用的图像联系起来。理解了粒子模型，就不会犯诸如“光强越大、光电子动能越大”的常见错误。

3. Master the Mathematical Toolkit | 精通数学工具

An A* physicist must be fluent in algebra, trigonometry, logs, and basic calculus ideas. You’ll need to manipulate equations quickly and accurately. For example, rearranging T = 2π√(l/g) for g, or taking natural logs of both sides of N = N₀ e⁻λᵗ to produce ln N = ln N₀ – λt.

物理 A* 学生必须熟练运用代数、三角、对数和基础微积分思想。你需要快速准确地变形公式，例如从 T = 2π√(l/g) 解出 g，或者对 N = N₀ e⁻λᵗ 两边取自然对数得到 ln N = ln N₀ – λt。

Know your way around units and significant figures. CIE marks are allocated for correct units in final answers and for quoting results to an appropriate number of significant figures (usually 2 or 3 based on given data). Practise converting between eV and J, or between N C⁻¹ and V m⁻¹ for electric field strength.

熟练掌握单位和有效数字。CIE 会在最终答案的正确单位和合适有效数字上给分（通常依据题目数据取 2 或 3 位）。练习 eV 与 J 的换算，以及电场强度单位 N C⁻¹ 和 V m⁻¹ 的转换。

Show all your working clearly. Even if you slip in the final arithmetic, a well-structured solution earns the vast majority of method marks. Use standard notation and underline your final answer.

清晰展示全部解题步骤。即便最后计算有小错，结构清晰的解答也能拿到绝大部分步骤分。使用标准符号，并在最终答案下划横线。

4. Past Papers: the Ultimate Weapon | 真题：终极武器

Begin past paper practice early — at least five months before the exam. I tackled every Paper 4 from 2016 to 2023 at least twice: first untimed, then under strict exam conditions. This builds familiarity with the style and the mark schemes.

尽早开始真题训练——至少考前五个月。我把 2016 至 2023 年的所有 Paper 4 都做了至少两遍：第一遍不限时，第二遍严格模拟考试。这能让你熟悉题型和评分标准。

After marking, study the mark scheme thoroughly. You’ll notice that many ‘explain’ questions require precise phrasing. For instance, to explain why a charged particle moving parallel to a magnetic field experiences no force, you must state: ‘F = BQv sin θ; θ = 0° or 180°, so sin θ = 0, therefore F = 0.’ Missing the mention of sin θ loses a mark.

每套题做完后，透彻分析评分标准。你会发现很多“解释”题对用语要求极其精确。例如，解释为什么带电粒子平行于磁场运动不受力，你必须写明：“F = BQv sin θ；θ = 0° 或 180°，故 sin θ = 0，因此 F = 0”。漏提 sin θ 就会丢分。

Keep an error log. For every mistake, note the correct concept or technique. Review this log weekly. Common errors, like forgetting to square the radius in centripetal force calculations, will eventually stick and you’ll stop repeating them.

建立错题日志。每道错题都记下正确的概念或方法，每周复习一次。诸如向心力计算时忘记将半径平方等常见错误，经过反复提醒，最终就会牢记，不再重犯。

5. Ace Paper 5 (Planning, Analysis and Evaluation) | 攻克 Paper 5（实验规划、分析与评估）

Paper 5 is often where top students separate themselves. Question 1 asks you to design an experiment. Use a standard framework: aim, independent/dependent/control variables, apparatus list, labelled diagram, step-by-step procedure, method of data analysis (what graph to plot, how gradient gives the target quantity), and safety precautions.

Paper 5 经常是拉开尖子生差距的地方。第一题要求设计实验。使用标准框架：实验目的，自变量/因变量/控制变量，仪器清单，带标注的示意图，分步操作流程，数据分析方法（画什么图，如何由斜率求得目标量），以及安全措施。

Question 2 provides raw data and asks you to process it, draw a graph, calculate gradient and intercept, and discuss uncertainties. Practise calculating absolute and percentage uncertainty, and learn to propagate errors in sums, products, and powers. Always use a sharp pencil and a ruler for your graph, and ensure the plotted points occupy more than half the grid.

第二题提供原始数据，要求处理数据、绘图、计算斜率和截距，并讨论不确定度。练习计算绝对不确定度与百分比不确定度，学会在加减、乘除和幂运算中传递误差。作图务必用铅笔和直尺，确保数据点占据网格面积的一半以上。

Common weaknesses: forgetting axis labels with units, drawing a line that doesn’t fit the trend, and giving vague evaluations like ‘take more readings’. Instead, suggest specific improvements: ‘use a set square to align the ruler with the bench to reduce parallax error when measuring the height’, or ‘clamp the meter rule vertically to eliminate zero error’.

常见弱点：坐标轴未标单位，画的线不符合趋势，以及评价含糊如“多取几组数据”。应该给出具体改进建议：“用三角板将直尺对准工作台以减少测量高度时的视差”，“竖直夹紧
