1. Introduction to AMC | AMC简介
The American Mathematics Competitions, sponsored by the Mathematical Association of America (MAA), are designed to foster problem-solving ability and a deeper understanding of mathematics. The series includes AMC 8 (for middle school), AMC 10 and 12 (for high school), and the American Invitational Mathematics Examination (AIME) for top scorers. Performing well on these exams opens doors to the USA(J)MO and, ultimately, the International Mathematical Olympiad (IMO).
美国数学竞赛由美国数学协会赞助，旨在培养解决问题的能力和对数学更深层次的理解。该系列包括AMC 8（面向初中）、AMC 10和12（面向高中），以及为高分者设置的美国数学邀请赛(AIME)。在这些考试中表现出色将打开通向美国数学奥林匹克乃至国际数学奥林匹克的大门。
2. Understanding the Exam Structure | 理解考试结构
AMC 8 contains 25 multiple-choice questions to be solved in 40 minutes; calculators are not allowed. AMC 10 and AMC 12 each consist of 25 questions with a 75-minute time limit. In AMC 10/12, a correct answer earns 6 points, a blank answer earns 1.5 points, and a wrong answer gives 0 points. This scoring system rewards careful guessing and time management. Approximately the top 2.5% of AMC 10 participants and top 5% of AMC 12 participants qualify for the AIME.
AMC 8包含25道选择题，限时40分钟，不允许使用计算器。AMC 10和AMC 12各有25道题，限时75分钟。在AMC 10/12中，答对得6分，留空得1.5分，答错得0分。这种评分机制鼓励谨慎猜测和时间管理。大约AMC 10前2.5%和AMC 12前5%的参赛者晋级AIME。
3. Core Topics Covered | 涵盖核心主题
The AMC exams cover a broad range of mathematical areas. You must be comfortable with algebra (including equations, inequalities, and functions), geometry (triangles, circles, area, and volume), number theory (prime numbers, divisibility, modular arithmetic), combinatorics (counting principles, permutations, combinations), and probability. For AMC 12, precalculus topics such as logarithms, complex numbers, and trigonometry become essential.
AMC考试涵盖广泛的数学领域。你必须熟练掌握代数（包括方程、不等式和函数）、几何（三角形、圆、面积和体积）、数论（素数、整除性、模运算）、组合数学（计数原理、排列、组合）以及概率。对于AMC 12，对数、复数、三角学等预备微积分内容也变得至关重要。
4. Essential Problem-Solving Strategies | 基本解题策略
Developing a toolkit of general strategies is as important as learning content. Learn to use the process of elimination: discard obviously wrong answer choices to improve your guessing odds on difficult questions. Apply extreme cases or boundary values to simplify complex problems. Practice drawing clear diagrams to visualize geometric relationships. Master working backwards from the answer choices when direct solving is too time-consuming. Another powerful approach is to spot symmetric patterns or use parity arguments in number theory problems.
培养一套通用策略工具箱与学习知识内容同等重要。学会使用排除法：排除明显错误的选项，提高在难题上猜测的正确率。应用极端情况或边界值来简化复杂问题。练习绘制清晰的图形以可视化几何关系。掌握当直接求解太耗时时从答案选项反向推导的技巧。另一个强大的方法是识别对称模式或在数论问题中使用奇偶性论证。
5. Time Management Techniques | 时间管理技巧
With only 75 minutes for 25 questions in AMC 10/12, every minute counts. Start by scanning the entire test and identifying the easy problems (usually the first 10). Solve these first to build confidence and secure points. For medium-difficulty problems, set a mental timer of 3–4 minutes; if you get stuck, mark the question, leave it blank, and move on. Reserve the last 10 minutes to revisit skipped problems and decide whether to guess. Remember that a blank is worth 1.5 points, while a random guess among 5 choices has an expected value of 1.2 points — so educated guessing is key.
AMC 10/12只有75分钟完成25道题，每一分钟都很宝贵。开始时应快速浏览整份试卷，找出简单题目（通常是前10题）。先解答这些题以建立信心并确保得分。对于中等难度问题，设定3-4分钟的心理计时；如果卡住了，就标记题目、留空并继续。留出最后10分钟回顾跳过的题目并决定是否猜测。记住，留空得1.5分，而在5个选项中随机猜测的期望值为1.2分——因此有根据的猜测是关键。
6. Recommended Study Resources | 推荐学习资源
Quality resources make a significant difference in your preparation. The Art of Problem Solving (AoPS) textbooks are the gold standard, offering in-depth explanations and challenge problems. Past AMC and AIME exams with official solutions are freely available on the MAA website and the AoPS wiki. Additionally, online platforms such as Brilliant.org and Alcumus provide interactive practice. For structured learning, consider AoPS online classes or local math circles.

7. Creating a Personalized Study Plan | 制定个性化学习计划
Begin by taking a diagnostic test under timed conditions to assess your current level. Identify your weakest areas, whether it's geometry, combinatorics, or speed. Set a realistic goal — for example, aiming for the AIME qualification cutoff or simply improving your school score. Divide your study schedule into three phases: foundation building (reviewing concepts and doing basic problems), intensive practice (working on past AMC papers and topic-specific drills), and final mock testing (simulating real exams weekly). Allocate at least 3–5 study hours per week for 3–4 months before the exam.
首先在限时条件下进行一次诊断测试，以评估你当前的水平。找出你最薄弱的环节，无论是几何、组合数学还是速度。设定一个现实目标——例如，瞄准AIME晋级分数线，或者只是提高你的校内成绩。将你的学习计划分为三个阶段：基础构建（复习概念并做基础题）、强化练习（做往年AMC试题和专项训练）以及最后的模考阶段（每周模拟真实考试）。在考前至少安排3-4个月，每周学习3-5小时。
8. Importance of Mock Tests and Review | 模拟测试与回顾的重要性
Simulating the actual exam environment is irreplaceable. Print out a past AMC paper, set a 75-minute countdown, and work in a quiet space with no distractions. After finishing, thoroughly analyze every mistake: Was it a conceptual gap, a careless error, or poor time allocation? Keep an error log where you record the problem, the mistake, and the correct approach. Over time, this log will reveal patterns in your weaknesses and help you avoid repeating the same errors. Consistency in mock testing builds both speed and endurance.
模拟真实考试环境是不可替代的。打印一份往年AMC试卷，设置75分钟倒计时，并在不受干扰的安静空间里作答。完成后，彻底分析每个错误：是概念缺失、粗心失误还是时间分配不当？建立一个错题本，记录题目、错误原因和正确解法。久而久之，这个错题本会揭示你弱点的模式，帮助你避免重复犯错。持续的模拟测试能同时提升速度与耐力。
9. Common Mistakes to Avoid | 需要避免的常见错误
Many students lose points due to preventable errors. Rushing through the problem statement often leads to misinterpreting what the question is asking — always read carefully and underline key conditions. Calculation blunders in multi-step problems can be avoided by checking units and intermediate results. For geometry and counting problems, failing to consider alternative cases (e.g., overlapping regions, double-counting) is frequent. Also, avoid spending too much time on a single question early in the test; this can lead to panic later. Finally, do not neglect to practice without a calculator, as AMC does not allow them.
许多学生因可避免的错误而丢分。匆忙读题常导致误解题目要求——务必仔细阅读并划出关键条件。多步计算中的失误可以通过检查单位和中间结果来避免。在几何和计数问题中，忽略多种情形（例如重叠区域、重复计数）很常见。此外，避免在考试初段在一道题上花费太多时间，这会导致后面慌乱。最后，不要忽视无计算器练习，因为AMC不允许使用计算器。
10. Building Mental Stamina and Confidence | 培养心理承受力与信心
AMC preparation is as much a mental journey as an intellectual one. Long practice sessions can cause burnout, so include short breaks and mix up the topics you study. Develop a growth mindset: view challenging problems as opportunities to learn, not as failures. When you encounter a difficult topic, break it down into smaller subskills and master them one by one. Before test day, use positive visualization — picture yourself calmly solving problems and managing time well. Confidence comes from consistent, incremental progress documented in your practice log.
AMC备考既是一场智力之旅，也是一次心理历练。长时间练习可能导致倦怠，所以要安排短暂休息并交叉学习不同主题。培养成长型思维：将挑战性问题视为学习机会，而非失败。当遇到棘手的主题时，将其分解为更小的子技能并逐一攻克。考前进行积极的视觉化想象——想象自己冷静解题并有效管理时间。信心源于练习日志中记录的一贯、渐进的进步。
11. Advanced Preparation for AIME | 为AIME进阶备考准备
If your goal is to qualify for AIME or beyond, your preparation must go beyond AMC-level tricks. AIME consists of 15 questions in 3 hours, all requiring integer answers between 0 and 999. There is no partial credit, and the problems demand rigorous, multi-step reasoning. Focus on mastering topics like advanced number theory (Diophantine equations, Legendre symbol), combinatorial identities, analytic geometry, and complex number geometry. Practice writing full logical solutions rather than just selecting answer choices. A recommended resource is the AoPS volume "Intermediate Algebra" and "Precalculus", as well as past AIME problems.
如果你的目标是晋级AIME或更进一步，你的准备必须超越AMC级别的技巧。AIME包含15道题，限时3小时，所有答案均为0到999之间的整数。没有部分分值，题目要求严谨的多步推理。重点掌握高等数论（丢番图方程、勒让德符号）、组合恒等式、解析几何和复数几何等主题。练习写出完整的逻辑解答，而不仅仅是选择答案。推荐资源是《AoPS 中级代数》和《预微积分》以及历年AIME试题。
12. Final Tips for Test Day | 考试当天最后提示
On the night before the exam, review your error log lightly but avoid cramming new material. Get a full night's sleep and eat a nutritious breakfast. Bring sharpened pencils, a good eraser, and a watch to keep track of time independently. Arrive at the test center early to settle in. During the test, if you feel your heart racing, take three deep breaths and refocus. Trust your preparation: you have solved hundreds of similar problems, and you are ready. Remember that the competition is first and foremost an opportunity to enjoy mathematical thinking.
考试前一晚，轻松翻阅错题本，但不要突击新材料。保证充足睡眠，吃一顿营养早餐。带上削好的铅笔、好用的橡皮和手表以独立计时。提前到达考场安顿下来。考试中若感到心跳加速，深呼吸三次并重新聚焦。相信你的准备：你已解答过成百上千道类似题目，你已准备就绪。请记住，这次竞赛首先是享受数学思维的机会。
