1. Understanding the SAT Math Test Structure | 理解SAT数学考试结构
The SAT Math section is divided into two parts: a 25-minute no-calculator section with 20 questions and a 55-minute calculator section with 38 questions. The total number of questions is 58, and most are multiple-choice, with some student-produced responses (grid-ins). The content covers four main areas: Heart of Algebra, Problem Solving and Data Analysis, Passport to Advanced Math, and Additional Topics in Math (geometry, trigonometry, and complex numbers). Familiarity with this structure helps you allocate time and mental energy effectively.
SAT数学部分分为两部分：一个25分钟、不允许使用计算器的部分，包含20道题；以及一个55分钟、允许使用计算器的部分，包含38道题。题目总数为58道，大部分为选择题，部分为自主作答（填空题）。内容涵盖四大领域：代数核心、问题解决与数据分析、进阶数学通行证，以及数学附加主题（几何、三角函数与复数）。熟悉这一结构有助于有效分配时间与脑力。
The no-calculator section tests your ability to reason quantitatively and manipulate expressions without computational aid, while the calculator section allows you to use approved devices to solve more complex problems. Understanding the distinction is crucial for choosing which problems to tackle first and for developing mental math skills.
无计算器部分考查你进行定量推理和运用表达式而无需计算辅助的能力，而计算器部分允许使用批准的设备来解决更复杂的问题。理解这一区别对于选择先做哪些题目以及培养心算能力至关重要。
2. Scoring and the Path to an 800 | 评分机制与通往800之路
The SAT Math score is derived from your raw score (the number of correct answers) which is then converted to a scaled score between 200 and 800 using a curve specific to each test. There is no penalty for wrong answers, so it is always beneficial to answer every question, even if you must guess. To achieve an 800, you typically need to answer all 58 questions correctly, or perhaps miss one question if the curve is lenient. Therefore, precision is paramount.
SAT数学分数由原始分（答对题数）经过每次考试特有的曲线转换成200至800之间的等级分。答错不扣分，因此回答每一道题总是有利的，哪怕需要猜测。为获得800分，你通常需要答对所有58题，或者如果曲线宽松，可能允许错一题。因此，准确性是至关重要的。
Aiming for perfection means you must minimize careless errors, such as misreading the question, forgetting to distribute a negative sign, or misinterpreting a graph. Develop a mindset of zero tolerance for silly mistakes and adopt checking procedures that can be completed within the time limit.
追求完美意味着必须将粗心错误降到最低，例如误读题干、忘记分配负号或错误解读图表。养成对低级错误零容忍的心态，并采取能在时限内完成的检查流程。
3. Core Knowledge Must-Haves | 核心知识点必备清单
st be able to solve for variables, interpret slopes and intercepts, and model real-world scenarios. For example: solving 2x + 3 = 11 yields x = 4. Understanding that the slope of the line y = 2x + 5 is 2 is fundamental.
掌握SAT数学需要熟练运用几个关键主题。代数核心涉及线性方程、不等式、方程组和图像。你必须能够求解变量、解释斜率和截距，并建立现实世界情景的模型。例如：解方程2x + 3 = 11得 x = 4。理解直线 y = 2x + 5 的斜率为2是基础。
− 5x + 6 = 0 into (x − 2)(x − 3) = 0, and understand the discriminant b² − 4ac. Functions and their transformations also appear frequently.
进阶数学通行证涵盖二次方程、多项式、根式和非线性表达式。你需要将二次方程如 x² − 5x + 6 = 0 分解因式为 (x − 2)(x − 3) = 0，并理解判别式 b² − 4ac。函数及其变换也频繁出现。
ables and scatterplots. You should be comfortable calculating percent change: (new − old)/|old| × 100% Statistics concepts like mean, median, mode, and standard deviation are tested in context.
问题解决与数据分析涉及比和比例、百分数、概率以及解读表格和散点图。你应该能够熟练计算百分比变化：(新值 − 旧值)/|旧值| × 100%，并理解相关关系与因果关系的区别。统计概念如平均数、中位数、众数和标准差会在情境中考查。
, cosine, and tangent (SOH CAH TOA). Radians and the equation of a circle (x − h)² + (y − k)² = r² are also tested. Complex numbers like i² = −1 appear occasionally.
附加主题包括面积、体积的几何公式，以及勾股定理：a² + b² = c²。直角三角形中的三角学使用正弦、余弦和正切（SOH CAH TOA）。弧度以及圆的方程 (x − h)² + (y − k)² = r² 也会考查。复数如 i² = −1 偶尔出现。
4. Effective Time Management Strategies | 高效时间管理策略
With approximately 1.4 minutes per question on the no-calculator section and 1.45 minutes on the calculator section, pacing is essential. Start by quickly scanning the test to identify easy questions that you can solve in under 30 seconds. Do not spend more than 2 minutes on any single question initially; mark it and return later. Use the first pass to secure all easy points.
无计算器部分平均每题约1.4分钟，计算器部分约1.45分钟，因此节奏至关重要。开始时快速浏览试卷，找出能在30秒内解决的基础题。初期在任何一道题停留不超过2分钟；先标记并稍后回做。第一遍确保所有容易得分的题目。
For the grid-in questions, plan to leave extra time because they require transferring your answer correctly. Practice bubbling or typing on the answer sheet to avoid transcription errors. In the calculator section, use your calculator wisely; do not rely on it for simple arithmetic that can be done mentally faster.
对于填空题，计划留出额外时间，因为它们需要正确转填答案。练习涂写答题纸或数字输入，以避免转录错误。在计算器部分，明智地使用计算器；不要依赖它处理可以通过心算更快完成的简单算术。
5. Smart Calculator Usage and Limitations | 计算器的巧妙使用与局限
A graphing calculator (such as the TI-84 Plus) is permitted and can be a game-changer. You can graph functions to find intersections, solve equations numerically, and verify answers. However, understanding when not to use the calculator is just as important. The no-calculator section is designed to test your algebraic manipulation skills, so practice doing operations like simplifying 3√12 by hand: 3√4×3 = 3×2√3 = 6√3.
图形计算器（如TI-84 Plus）是允许的，并能成为制胜法宝。你可以绘制函数图象以寻找交点，用数值方法解方程，并验证答案。但是，了解何时不使用计算器同样重要。无计算器部分旨在考查你的代数运算能力，因此要练习手算，例如化简 3√12：3√
