International physics competitions offer a remarkable opportunity to test your understanding beyond the classroom, sharpen problem-solving skills, and stand out on university applications. For Year 10 students following the CAIE curriculum, this is the perfect moment to build a strategic preparation plan that turns core IGCSE knowledge into competition-winning thinking. This guide will walk you through the key steps, from solidifying foundational concepts to mastering advanced problem‑solving techniques, and introduce the most suitable competitions for your level.
国际物理竞赛为你提供了在课堂之外检验理解、锻炼解题能力并在大学申请中脱颖而出的绝佳机会。对于正在学习 CAIE 课程的 Year 10 学生来说，现在正是构建战略性备考计划、将核心 IGCSE 知识转化为竞赛致胜思维的最佳时机。本攻略将带你走过关键步骤，从夯实基础概念到掌握高级解题技巧，并介绍最适合你当下水平的竞赛。
1. Understanding the Competition Landscape | 了解竞赛格局
Before diving into preparation, it is essential to know which competitions you are targeting. For Year 10 students, popular options include the British Physics Olympiad (BPhO) Junior Physics Challenge (online and written), the Canadian Association of Physicists’ High School Prize Exam, and regional Olympiads like the Singapore Physics Olympiad junior categories. Many of these require knowledge that closely aligns with the CAIE IGCSE Physics syllabus, but with a greater emphasis on applying concepts to unfamiliar scenarios and multi-step reasoning.
在投入备考之前，必须清楚你的目标竞赛有哪些。对 Year 10 学生而言，热门选择包括英国物理奥林匹克初级挑战（线上和笔试）、加拿大物理学家协会高中物理奖赛，以及新加坡物理奥赛初级组等区域性赛事。这些竞赛大多要求与 CAIE IGCSE 物理大纲紧密相关的知识，但更加强调将概念应用于陌生情境和多步推理。
These competitions vary in format: some are entirely multiple‑choice focusing on speed and accuracy, while others include structured questions that demand clear, logical written solutions. Understanding the format early helps you train the right skills. For example, the BPhO Junior Online Challenge consists of two 25‑minute papers of 25 multiple‑choice questions each, testing quick thinking under time pressure. The written Junior Physics Challenge includes longer, more descriptive problems that require diagram drawing and experimental design.
这些竞赛形式各异：有些是完全的选择题竞赛，侧重速度和准确性；有些则包含结构化问题，要求写出清晰、逻辑严密的解答过程。尽早了解形式有助于你针对性地训练技能。例如，BPhO 初级在线挑战赛由两份各 25 分钟、25 道选择题的试卷组成，考验时间压力下的快速思考。而初级物理挑战的笔试则包含更长、更具描述性的问题，需要画图和设计实验。
You should also note that many competitions award certificates at Gold, Silver, and Bronze levels, with top performers invited to further rounds. Even a Bronze award in a reputable competition is a valuable addition to your academic portfolio. Start by picking one or two competitions that suit your current level and build from there.
你还应注意，许多竞赛会颁发金、银、铜奖证书，顶尖选手会被邀请参加后续轮次。即使是在知名竞赛中获得铜奖，也是你学术履历上极具价值的补充。从选择一两个适合你当前水平的竞赛起步，然后逐步扩展。
2. Solidifying CAIE IGCSE Physics Foundations | 夯实 CAIE IGCSE 物理基础
Your textbook and past paper practice form the bedrock of competition success. The CAIE IGCSE Physics syllabus (0625) covers mechanics, thermal physics, waves, electricity, magnetism, and nuclear physics. You must be completely comfortable defining key quantities, recalling essential formulas, and performing unit conversions without hesitation. For example, you should be able to instantly state that pressure = force / area, that the moment of a force = force × perpendicular distance from pivot, and that electric current I = Q / t.
你的课本和历年真题练习是竞赛成功的基石。CAIE IGCSE 物理大纲 (0625) 涵盖力学、热物理、波动、电学、磁学和核物理。你必须能够毫不迟疑地定义关键物理量、回忆基本公式并进行单位换算。例如，你应该能立刻说出压强 = 力 / 面积，力矩 = 力 × 到支点的垂直距离，以及电流 I = Q / t。
Competition problems often take a core IGCSE principle and twist it slightly: instead of giving you a number, they might ask for a ratio; instead of a straightforward calculation, they might require you to explain why something happens. Therefore, deep conceptual understanding is crucial. Use the syllabus as a checklist. Go through each learning outcome and explain it aloud as if teaching a peer. Can you explain the difference between mass and weight clearly? Can you describe how a potential divider works without looking at notes?
竞赛题常常将一个核心 IGCSE 原理稍作变形：不是给你数字，而是让你求比值；不是直接计算，而是要求解释现象发生的原因。因此，深刻的概念理解至关重要。把大纲当作检查清单，逐条过每一个学习目标，像教同学那样大声解释出来。你能清楚地说明质量和重量的区别吗？能不看书就描述分压器的工作原理吗？
Past CAIE paper 2 (multiple choice) and paper 4 (structured questions) are excellent training tools. Aim for consistent scores above 85% before moving on to harder competition material. Time yourself strictly and review every mistake not as a slip, but as a symptom of a conceptual weakness that needs repair.
CAIE 的 past paper 2（选择题）和 paper 4（结构化问题）是极好的训练工具。在转向更难的竞赛材料之前，力争稳定获得 85% 以上的分数。严格计时，把每一个错误都看作是概念弱点需要修补的信号，而不是粗心失误。
3. Expanding Knowledge Beyond the Syllabus | 扩展大纲之外的知识
While IGCSE provides the framework, competitions often assume a slightly broader knowledge base. You do not need to master A‑level physics completely, but selectively learning key topics will give you an edge. For instance, simple harmonic motion (SHM) appears in many junior competitions; understand the relationship between displacement, velocity, and acceleration in a mass‑spring system. Another topic is Newton’s law of gravitation in vector form, which can help solve problems involving two masses and a test particle.
尽管 IGCSE 提供了框架，竞赛却常常假定学生拥有稍广的知识面。你无需完全掌握 A‑level 物理，但有选择地学习一些关键主题会带来优势。例如，简谐运动 (SHM) 出现在许多初级竞赛中；要理解弹簧振子系统中位移、速度和加速度之间的关系。另一个主题是矢量形式的万有引力定律，这有助于解决涉及两个质量和检验粒子的题目。
Use trusted resources such as the AQA A‑level Physics textbook or the MIT OpenCourseWare introductory physics notes. Focus on concepts, not derivations. For example, you might study the Doppler effect equation for sound and light:
f’ = f (v ± vₒ)/(v ∓ vₛ)
where f’ is the observed frequency, v is the wave speed, vₒ is the observer velocity, and vₛ is the source velocity. Such a formula can be grasped without full calculus if you approach it as a set of sign rules.
使用可靠的资源，如 AQA A‑level 物理教材或 MIT 开放课程中的基础物理笔记。专注于概念而非推导。例如，你可以学习声波和光波的多普勒效应方程：
f’ = f (v ± vₒ)/(v ∓ vₛ)
其中 f’ 是观察到的频率，v 是波速，vₒ 是观察者速度，vₛ 是波源速度。把该公式当作一套符号规则来理解，无需微积分也能掌握。
Other useful advanced topics include Kirchhoff’s circuit laws applied to multiple loops, centre of mass calculations for simple shapes, and the kinetic theory of gases linking pressure, volume, and molecular speed. Keep a dedicated notebook for these “extra” topics and link them back to your IGCSE knowledge.
其他有用的进阶主题包括基尔霍夫电路定律在多回路中的应用、简单形状的质心计算，以及将压强、体积和分子速率联系起来的分子动理论。为这些“额外”主题准备一个专用笔记本，并始终与你的 IGCSE 知识建立联系。
4. Sharpening Mathematical Skills | 强化数学技能
Physics competitions are often a test of applied mathematics as much as of physics. You will encounter problems requiring algebraic manipulation, ratio reasoning, trigonometry, and basic graph analysis. Start by ensuring you are fluent with standard form, prefixes (nano, micro, milli, kilo, mega), and significant figures. Then, practice rearranging multi‑variable equations without plugging in numbers until the final step. This skill reduces rounding errors and reveals symmetries.
物理竞赛往往既是对物理的考察，也是对应用数学的测试。你会遇到需要代数运算、比例推理、三角学和基础图像分析的问题。首先要确保熟练使用科学记数法、词头（纳、微、毫、千、兆）和有效数字。然后练习不代入数字、直到最后一步才对多变量方程进行变形。这个技能能减少舍入误差，并揭示对称性。
Trigonometry is especially important in resolving vectors. Be comfortable with sin, cos, tan and the sine and cosine rules for non‑right‑angled triangles. A typical competition problem might ask for the tension in two ropes at angles 30° and 45° supporting a weight; you must be able to set up equilibrium equations quickly: ΣFₓ = 0, ΣFᵧ = 0.
三角学在分解矢量时尤其重要。要熟练掌握正弦、余弦、正切，以及非直角三角形的正弦定理和余弦定理。一道典型的竞赛题可能会问：两绳夹角 30° 和 45° 悬挂一重物，求两绳张力；你必须能迅速建立平衡方程：ΣFₓ = 0，ΣFᵧ = 0。
Graph skills also need upgrading. Competitions love giving graphs of motion, force‑extension, or voltage‑current, and asking for gradients, areas, or intercept interpretations. Practice calculating the gradient of a best‑fit line, determining the equation of a straight line in physics form (like V = ε – Ir for a battery), and converting non‑linear graphs to linear form using substitution (e.g., T² against L for a pendulum).
图像技能也需要升级。竞赛喜欢给出运动、力-伸长或电压-电流图像，并要求解释斜率、面积或截距。练习计算最佳拟合线的斜率，确定物理中的直线方程（如电池的 V = ε – Ir），以及通过代换将非线性图像转化为线性形式（例如单摆的 T² 对 L 图像）。
5. Mastering Experimental and Data Analysis Skills | 掌握实验与数据分析技能
Many junior competitions include a section on experimental design or data analysis. Even in theory papers, questions about reading instruments, calculating uncertainties, and evaluating systematic vs. random errors are common. You must know the difference between precision and accuracy, how to reduce parallax errors, and when to repeat measurements. For example, measuring the period of a pendulum accurately requires measuring the time for 10 oscillations, not just one.
许多初级竞赛包含实验设计或数据分析部分。即使在理论卷中，关于读数、计算不确定度以及评估系统误差与随机误差的问题也很常见。你必须清楚精确度与准确度的区别，如何减小视差，以及何时应重复测量。例如，准确测量单摆周期，需要测量 10 次振荡的时间，而非单次。
Learn to express an uncertainty in a measurement, for instance 5.6 ± 0.1 cm, and to combine uncertainties for addition and subtraction (add absolute uncertainties) and for multiplication and division (add percentage uncertainties). A simple rule: if Q = a × b, then %ΔQ = %Δa + %Δb. Being able to efficiently calculate and present uncertainties will earn you marks that others leave on the table.
学会表示测量不确定度，例如 5.6 ± 0.1 cm，并掌握加减运算时的不确定度合成（绝对不确定度相加）以及乘除运算时的合成（百分比不确定度相加）。一个简单法则：若 Q = a × b，则 %ΔQ = %Δa + %Δb。能够高效计算并呈现不确定度，将使你拿到别人丢掉的分。
Also, practise interpreting data in tables and spotting trends or anomalies. A common competition question shows a table with one value that does not fit the trend; you are expected to identify it, suggest a possible reason, and state what should be done with that reading in calculations (usually ignore it). Develop the habit of quickly plotting a rough graph in your mind to see if your conclusions make sense.
此外，练习解读表格数据，发现趋势或异常点。常见的竞赛题会展示一张表格，其中有一个值不符合趋势；要求你找出它，提出可能的原因，并说明在计算中应如何处理该读数（通常是忽略它）。养成在脑中快速粗略绘图的习惯，以判断你的结论是否合理。
6. Problem‑Solving Strategies and Techniques | 解题策略与技巧
Competition problems rarely yield to a single formula substitution. Instead, adopt a structured approach: read the problem carefully, draw a clear diagram labelling all forces, velocities, and known values, and list the variables and the target quantity. Then, work backwards from what is asked to what is given, identifying the bridges—conservation laws, equations of motion, or circuit rules.
竞赛题极少能靠单一代入公式解决。应采用结构化的方法：仔细读题，画出清晰的示意图并标注所有力、速度和已知值，列出变量和待求量。然后从问题出发倒推至已知条件，找出它们的桥梁——守恒定律、运动方程或电路规则。
Identify the crucial physical principle first. Is it a collision? Think conservation of momentum. Is it a roller‑coaster problem? Think conservation of energy. Is it a circuit with many loops? Think Kirchhoff’s laws. Write down the governing equation in symbol form before you put in numbers. This keeps your thinking clean and allows you to check dimensional consistency.
首先识别关键的物理原理。是碰撞吗？考虑动量守恒。是过山车问题吗？考虑能量守恒。是多回路电路吗？考虑基尔霍夫定律。在代入数字之前，先用符号写出控制方程。这能保持思维清晰，并让你检验量纲的一致性。
A powerful tool is the “limiting case” test: if you let a variable go to zero or infinity, does the expected result make physical sense? For example, if a formula for speed involves mass, check what happens when mass → ∞. If the speed becomes zero, that might be plausible. Also, multiple‑choice questions: often you can eliminate two options by simple unit analysis. If the answer has units of metres per second squared and the question asks for a time, discard it.
一个强大的工具是“极限情况”检验：如果让某个变量趋于零或无穷，预期的结果在物理上是否有意义？例如，如果速度公式中含有质量，检查当质量 → ∞ 时会发生什么。如果速度变为零，那或许是合理的。对于选择题，常常可以通过简单的单位分析排除两个选项。如果答案的单位是米每二次方秒，而题目要求的是时间，就把它排除。
7. Time Management and Mock Exam Practice | 时间管理与模拟练习
Competitions are time‑pressured. You must learn to move quickly without losing accuracy. Start by working through past competition papers under timed conditions. For a 60‑minute paper, allocate 1 minute per mark as a rough guide, but remember that some marks are quicker to earn than others. Never spend 10 minutes on a 1‑mark multiple‑choice question. Flag it and return later.
竞赛中的时间压力很大。你必须学会快速推进而不失准确性。从在计时条件下做历年竞赛真题开始。对于 60 分钟的试卷，大致可按 1 分钟 1 分来分配，但要记住有些分比另一些更易得。绝对不要在一道 1 分的选择题上花费 10 分钟。先做标记，稍后再回看。
Create a realistic practice schedule. For example, dedicate one weekday evening to revising a specific topic, and every other Saturday morning to a full‑length mock paper. After each mock, spend at least 30 minutes analysing your performance. Identify not only what you got wrong, but why. Were you stuck on a concept, a mathematical step, or did you simply misread the question? Classify your errors and track them over time.
制定切实可行的练习计划。例如，用平日晚间复习一个特定主题，每隔一周的周六上午进行一次完整的模拟考试。每次模拟后，至少花 30 分钟分析自己的表现。不仅要找出错误内容，还需找出错误原因：是概念卡住、数学步骤不对，还是仅仅误读了题目？将错误分类，并随时间追踪。
Use a timer during your study sessions as well. When solving a problem set, aim to do each question in under a set limit. Gradually reduce the time allowance. Speed is built through repeated exposure to the same patterns. Maintain an error log where you write the problem, your mistake, and the correct approach. Review it weekly.
在学习时段也要使用计时器。做练习题时，力争在设定时限内完成每道题。逐渐缩短时间限制。速度是通过反复接触相同模式培养出来的。维护一个错题本，记下题目、你的错误以及正确解法。每周回顾一次。
8. Recommended Competitions and Resources | 推荐竞赛与资源
For Year 10, start with the BPhO Junior Physics Challenge. It is designed for students up to Year 10 and covers material closely aligned with IGCSE Physics, with an emphasis on thinking skills. The online version is particularly accessible and a great first step. Another highly recommended competition is the International Physics Olympiad (IPhO) Junior categories, though entry may be through national teams. Also consider the “Physics Bowl” in the USA (Division 1 for first‑year physics learners) and the “Sir Isaac Newton Exam” from the University of Waterloo.
针对 Year 10，从 BPhO 初级物理挑战开始。该竞赛专为 Year 10 及以下学生设计，内容与 IGCSE 物理紧密对接，并强调思维技能。在线版本尤为便捷，是绝佳的入门台阶。另一个高度推荐的竞赛是国际物理奥林匹克初级组别，尽管参赛往往需通过国家队选拔。也可考虑美国的“物理碗”（Division 1 面向学物理第一年的学生）以及滑铁卢大学的“牛顿考试”。
Essential resources include the official CAIE IGCSE Physics textbook and revision guide, past competition papers from BPhO (available on their website), and the book “Thinking Physics” by Lewis Carroll Epstein, which uses conceptual puzzles to build intuition. Websites such as Isaac Physics (University of Cambridge) offer a wealth of free, graded problems that bridge IGCSE and competition levels. Additionally, YouTube channels like “Physics Online” and “Flipping Physics” provide clear explanations.
必备资源包括官方的 CAIE IGCSE 物理教材与复习指南、BPhO 官网提供的历年竞赛真题，以及 Lewis Carroll Epstein 的《Thinking Physics》，该书通过概念性谜题培养直觉。诸如剑桥大学的 Isaac Physics 网站提供了大量免费的、分级递进的问题集，是连接 IGCSE 与竞赛水平的桥梁。此外，YouTube 频道如 “Physics Online” 和 “Flipping Physics” 可提供清晰的讲解。
| Competition / Resource | Level | Format |
|---|---|---|
| BPhO Junior Online Challenge | Year 10 | Multiple‑choice, timed |
| BPhO Junior Physics Challenge (written) | Year 10 | Structured questions |
| Isaac Physics (online problems) | GCSE to A‑level | Interactive, graded |
| Thinking Physics (book) | Introductory | Conceptual puzzles |
9. Common Pitfalls and How to Avoid Them | 常见误区与规避方法
One major mistake is treating physics as a collection of formulas to be memorised. Competition setters love to design problems that cannot be solved by a straightforward plug‑and‑chug. You must understand the principles to adapt. For instance, a problem might involve a block sliding down an arc, not a straight slope; you need to use energy conservation, not kinematics, because acceleration is not constant.
一个主要错误是把物理当作一堆需要记忆的公式。竞赛出题人喜欢设计那些无法通过直接代入数字解决的题目。你必须理解原理以灵活变通。例如，一道题可能会涉及滑块沿弧面下滑，而非直线斜坡；此时你需要用能量守恒，而不是运动学，因为加速度不恒定。
Another pitfall is neglecting units and dimensions during calculations. Always include units in your working, and verify that your final answer has the correct units. A speed in m/s that results in 250 m⋅s² after multiplication indicates an algebraic error. Also, avoid rounding intermediate results too early; keep them in your calculator and only round the final answer to an appropriate number of significant figures.
另一个误区是在计算中忽略单位和量纲。始终在运算过程中带上单位，并核实最终答案是否有正确的单位。一个以 m/s 为单位的速率，相乘后若得到 250 m⋅s²，就表明出现了代数错误。此外，不要过早对中间结果进行舍入；将其保留在计算器中，仅将最终答案修约至合适位数的有效数字。
Students often misread graphs, confusing the slope of a distance‑time graph (speed) with the slope of a speed‑time graph (acceleration). Train yourself to pause and ask: what exactly is being plotted on each axis? What does the gradient represent? What does the area represent? This habit will prevent careless misinterpretations.
学生还常常误读图像，混淆距离‑时间图像的斜率（速率）与速率‑时间图像的斜率（加速度）。训练自己停下来问一问：每个坐标轴具体画的是什么？斜率代表什么？面积代表什么？这个习惯会防止粗心大意造成的错误解读。
10. Building a Competition Mindset | 培养竞赛心态
Competition success is not solely about knowledge; it is also about staying calm, managing stress, and maintaining curiosity. Start by setting realistic, incremental goals. Your first aim could be to achieve a Bronze certificate, then Silver, then Gold. This progressive approach keeps motivation high and prevents burnout. Celebrate small victories, like solving a difficult problem after multiple attempts, or recognizing a pattern in a new question.
竞赛的成功不仅靠知识，还在于保持冷静、管理压力和呵护好奇心。要从设立现实且渐进的目标开始。你的第一个目标可以是获得铜奖，然后是银奖，接着是金奖。这种渐进的策略能保持高昂的动机并防止倦怠。庆祝小胜利，比如经过多次尝试后解出一道难题，或在新题中认出了一个模式。
Build a study group with like‑minded friends. Explaining a problem to someone else solidifies your own understanding and exposes gaps. Group discussions also expose you to different ways of approaching the same problem. If a study group is not feasible, maintain a journal where you explain solutions in your own words. The act of writing clarifies thinking.
与志趣相投的朋友组成学习小组。向别人讲解题目能巩固你自己的理解，并暴露知识漏洞。小组讨论还能让你接触到同一问题的不同切入点。如果无法组建学习小组，可以坚持写一本日志，用自己的话解释解题思路。写作的过程能厘清思维。
Balanced life is essential. Adequate sleep, physical exercise, and breaks from screen time improve cognitive performance. Tired brains make elementary mistakes. Schedule your practice sessions when you are most alert, and never sacrifice sleep for last‑minute cramming. Moreover, keep the big picture in mind: physics competitions are a journey of exploration, not a box‑ticking exercise for an application.
平衡的生活至关重要。充足的睡眠、体育锻炼和远离屏幕的休息能提升认知表现。疲惫的大脑会犯低级错误。将练习安排在你最清醒的时段，绝不要为了临时抱佛脚而牺牲睡眠。此外，要始终心怀大局：物理竞赛是一趟探索之旅，而不是申请表的打勾练习。
11. Sample Competition‑Style Problem Walkthrough | 竞赛风格样题详解
Let us apply the strategies to a sample problem: A 2.0 kg block is released from rest at point A on a frictionless track that forms a circular arc of radius 0.80 m. Point B is the lowest point of the arc. Calculate the speed of the block at point B and the normal force exerted by the track on the block at that point.
让我们将策略应用于一道样题：一个 2.0 kg 的滑块从静止释放于 A 点，该点位于一个半径为 0.80 m 的光滑圆弧轨道上。B 点是圆弧的最低点。计算滑块在 B 点的速率以及在该点轨道对滑块的法向力。
First, draw the diagram. Identify the vertical drop from A to B. If the radius is 0.80 m and the angle is not given, assume the arc is a quarter‑circle, so drop h = 0.80 m. Use conservation of energy: mgh = ½mv², so v = √(2gh) = √(2 × 9.8 × 0.80) ≈ 3.96 m/s. At B, the forces are weight mg down and normal force N up. The centripetal acceleration is v²/r directed upward, so N – mg = mv²/r. Compute mv²/r = 2.0 × (3.96)² / 0.80 ≈ 39.2 N, thus N = 19.6 + 39.2 = 58.8 N. Notice how we avoided numbers until the end to get neat symbolic results.
首先，画出示意图。确定从 A 到 B 的垂直下落高度。若半径为 0.80 m 且未给角度，假设弧为四分之一圆，则下落高度 h = 0.80 m。利用能量守恒：mgh = ½mv²，因此 v = √(2gh) = √(2 × 9.8 × 0.80) ≈ 3.96 m/s。在 B 点，力有向下的重力 mg 和向上的法向力 N。向心加速度 v²/r 向上，故 N – mg = mv²/r。计算 mv²/r = 2.0 × (3.96)² / 0.80 ≈ 39.2 N，因此 N = 19.6 + 39.2 = 58.8 N。注意我们直到最后才代入数字，以得到整洁的符号表达式。
This problem illustrates the fusion of energy conservation and circular dynamics, two core topics that often appear together in competitions. The step‑by‑step approach—diagram, principle identification, algebraic solution, numerical substitution—is a template for tackling any such problem.
这道题展示了能量守恒与圆周动力学的结合，这两个核心主题在竞赛中常常一同出现。分步方法——作图、识别原理、代数求解、代入数值——是处理任何此类问题的模板。
12. Final Tips and Long‑Term Planning | 终极提示与长远规划
Start early and be consistent. A sound preparation plan for Year 12 competitions can begin as early as Year 9 or 10. Use the summer holidays to work through one competition syllabus completely. Create a revision timeline that maps topics against weeks, leaving the last two weeks before a competition for intensive mock practice and review of weak areas.
早起步，持之以恒。一项针对 Year 12 竞赛的稳妥准备计划，最早可从 Year 9 或 10 开始。利用暑假完整地过一遍竞赛考纲。制定一个复习时间表，将各主题分配到每周，留出竞赛前的最后两周进行密集模拟练习和薄弱环节回顾。
Above all, stay curious. Physics is the fundamental science that explains everything from galaxies to gluons. The thrill of solving a tough problem, of understanding a counter‑intuitive phenomenon, is what drives the greatest physicists. Let that thrill power your preparation. Track your progress, lean on your teachers and peers, and trust the process.
最重要的是，保持好奇心。物理是解释从星系到胶子的基础科学。解出一道难题、理解一个反直觉现象的激动，正是驱使最伟大物理学家的动力。让这种激动为你的备考充电。追踪自己的进步，依靠老师和同伴，并信任这个过程。
