📚 Edexcel Maths: End-of-Term Revision Checklist | Edexcel 数学：期末复习提纲
As the term draws to a close, a structured revision checklist is essential for Edexcel Maths students aiming to consolidate key concepts and boost exam confidence. This guide provides a topic-by-topic review framework, practical strategies, and a focus on common pitfalls to ensure you are fully prepared for end-of-term assessments.
随着学期的结束，一份结构清晰的复习提纲对于 Edexcel 数学考生来说至关重要。它能够帮助你巩固核心概念，提升应试信心。本指南提供逐主题的复习框架、实用策略以及常见错误的提醒，确保你为期终评估做好充分准备。
1. Organise Your Revision Plan | 制定复习计划
Start by mapping out all the topics you need to cover. List them under the main strands: Number, Algebra, Geometry, Statistics, and Ratio and Proportion. Allocate more time to topics you find challenging, and set clear daily goals.
首先列出你需要复习的所有主题。将它们归类到主要模块下：数与计算、代数、几何、统计和比例。对于你觉得困难的主题，分配更多时间，并设定明确的每日复习目标。
Create a timetable that mixes difficult topics with easier ones to avoid burnout. Use past papers to identify your weak areas, and schedule regular practise sessions under timed conditions.
制定一张将难点与易点交替安排的复习时间表，避免过度疲劳。利用历年真题找出薄弱环节，并定期安排限时练习。
2. Mastering Number and Algebra | 掌握数与代数
Ensure your foundational number skills are rock solid: fractions, decimals, percentages, and order of operations (BIDMAS). Practise converting between these forms and solving real-world proportion problems.
确保你的基础数字技能非常扎实：分数、小数、百分数以及运算顺序（BIDMAS）。练习在这些形式之间进行转换，并解决实际的比例问题。
In algebra, focus on simplifying expressions, expanding brackets, factorising quadratics, and rearranging formulae. Quadratic equations are a high-frequency topic – practise both factorisation and using the quadratic formula:
在代数部分，重点练习化简表达式、展开括号、因式分解二次式以及公式变形。二次方程是高频考点——既要练习因式分解法，也要熟练使用求根公式：
x = [-b ± √b² − 4ac] / (2a)
掌握求根公式：x = [-b ± √b² − 4ac] / (2a)。反复练习以便在考试中快速准确地应用。
3. Graphs and Functions | 图形与函数
ind gradients, and interpret intercepts. The gradient between two points (x₁, y₁) and (x₂, y₂) is calculated as:
你必须能够根据直线方程 y = mx + c 绘制图形，求斜率，以及解释截距。两点 (x₁, y₁) 和 (x₂, y₂) 之间的斜率计算公式为：
m = (y₂ − y₁) / (x₂ − x₁)
Practise drawing graphs for quadratic functions and identifying their turning points. Recognise the shape of cubic, reciprocal, and exponential graphs.
练习绘制二次函数图形并识别其顶点。辨认三次函数、反比例函数和指数函数的图形特征。
4. Geometry and Measures | 几何与测量
Memorise formulas for area and volume: triangle, parallelogram, trapezium, circle, cylinder, sphere, and composite shapes. The area of a circle is:
熟记面积和体积公式：三角形、平行四边形、梯形、圆、圆柱体、球体以及组合图形。圆的面积公式为：
A = πr²
Be comfortable converting between units of length, area, and volume. Understand how to use scale factors for similar shapes and interpret bearings.
熟练掌握长度、面积和体积单位的换算。理解相似形中比例因子的用法，并能正确解读方位角。
5. Probability and Statistics | 概率与统计
For probability, practise drawing tree diagrams and using the AND/OR rules. Tree diagrams are especially useful for conditional probability questions and repeated events.
对于概率，练习绘制树状图并运用“与/或”规则。树状图对于条件概率和重复事件类题目尤为有用。
In statistics, revise mean, median, mode, and range; learn how to construct and interpret cumulative frequency diagrams, histograms, and box plots. Pay close attention to the difference between discrete and continuous data.
在统计部分，复习平均数、中位数、众数和极差；学会绘制并解读累积频率图、直方图和箱形图。特别注意离散数据与连续数据的区别。
6. Trigonometry and Pythagoras | 三角学与勾股定理
Pythagoras' here c is the hypotenuse. Practise finding missing sides and applying this to 3D problems.
勾股定理指出，在直角三角形中，a² + b² = c²，其中 c 为斜边。练习求未知边长，并将其应用于三维立体问题。
a² + b² = c²
For trigonometry, recall the sine, cosine, and tangent ratios (SOH CAH TOA). For non-right-angled triangles, use the sine rule and cosine rule:
在三角学中，牢记正弦、余弦和正切比（SOH CAH TOA）。对于非直角三角形，运用正弦定理和余弦定理：
Sine Rule: a / sin A = b / sin B = c / sin C
Cosine Rule: a² = b² + c² − 2bc cos A
练习使用正弦定理和余弦定理：a / sin A = b / sin B = c / sin C，以及 a² = b² + c² − 2bc cos A。
7. Vectors and Transformations | 向量与变换
Vectors describe magnitude and direction. You must be able to add, subtract, and multiply vectors by scalars. Represent them as column vectors and solve geometry problems involving parallel and collinear vectors.
向量用于描述大小和方向。你需要掌握向量的加法、减法和数乘，用列向量表示它们，并解决涉及平行和共线向量的几何问题。
Transformations include translations, reflections, rotations, and enlargements. Be able to describe fully each transformation and find the centre of enlargement or the equation of a mirror line.
变换包括平移、反射、旋转和放大。能够完整描述每一种变换，并找到放大中心或镜线的方程。
8. Problem-Solving Strategies | 解题策略
Many exam questions require multi-step reasoning. Break down complex problems into smaller, manageable steps. Use bar models, ratio tables, or algebraic representations to clarify relationships.
许多试题需要进行多步推理。将复杂问题拆分为易于处理的小步骤。使用条形模型、比例表格或代数形式来理清关系。
Always show your working clearly. Even if your final answer is wrong, method marks can be awarded. Check your answers by substituting back into equations or using estimation.
始终清楚写明解题步骤。即使最后答案有误，书写过程仍可能得到方法分。通过代入方程或估算来验证你的答案。
9. Exam Technique and Time Management | 考试技巧与时间管理
During the exam, read the whole question carefully before starting. Identify what the question is asking and note down key information. Allocate time proportionately to the marks available – a 3-mark question should not take as long as a 6-mark problem.
考试时，先仔细阅读整个题目再动笔。确定问题要求，记下关键信息。根据分值按比例分配时间——3分题不应占用与6分题同样多的时间。
If you are stuck on a question, move on and come back later. Do not leave any question unanswered – even a partial attempt may earn marks. Bring all necessary equipment: calculator, ruler, compass, protractor, and spare pens.
如果被某一题卡住，先做后面的题目，再回头处理。不要留空——哪怕写出一部分也可能得分。带齐所有必要工具：计算器、直尺、圆规、量角器和备用笔。
10. Common Pitfalls and How to Avoid Them | 常见错误及避免方法
Common errors include forgetting to write units, mixing up area and perimeter formulas, and sign errors when expanding brackets. Double-check your signs and units in every step, especially in multi-part questions.
常见错误包括忘记写单位、混淆面积与周长公式，以及展开括号时的符号错误。每一步都要仔细检查符号和单位，特别是在多步问题中。
When using a calculator, make sure it is in the correct mode (degrees for trigonometry). Bracket negative numbers when squaring to avoid incorrect results. Practise non-calculator skills regularly to strengthen mental arithmetic and estimation.
使用计算器时，确保模式正确（三角学使用度模式）。平方负数时要加括号以避免错误。定期进行无计算器练习，以加强心算和估算能力。
11. Formula Recall Drill | 公式记忆练习
Although Edexcel may provide a formula sheet for some papers, you still need to memorise key relationships for speed and confidence. Write out essential formulas daily until they become second nature.
尽管Edexcel某些试卷会提供公式表，但为了解题速度与信心，你仍需熟记关键关系式。每天默写基本公式，直到熟能生巧。
sm = cross-sectional area × length, Pythagoras: a² + b² = c², quadratic formula: x = [-b ± √b² − 4ac] / 2a, and trigonometric ratios: sin = opp/hyp, cos = adj/hyp, tan = opp/adj.
必须熟记的公式：长方形面积 = 长 × 宽，三角形面积 = ½ × 底 × 高，圆面积 = πr²，周长 = 2πr 或 πd，棱柱体积 = 截面积 × 长，勾股定理：a² + b² = c²，求根公式：x = [-b ± √b² − 4ac] / 2a，以及三角函数比：sin = 对边/斜边，cos = 邻边/斜边，tan = 对边/邻边。
12. Final Week Booster | 考前冲刺
In the final week, focus on completing full past papers under timed, exam-like conditions. Mark them ruthlessly and take note of every small mistake – then revisit the relevant topic. Prioritise topics that carry high marks, such as algebra and problem-solving.
最后一周，集中进行限时真题模拟训练，模拟真实考试环境。严格批改，把每一个小错误都记录下来——然后重新复习相关知识点。优先处理分值高的主题，如代数和综合解题。
Develop a positive mindset – you have prepared thoroughly. Read questions calmly, manage your time, and trust your revision. A good night's sleep and proper hydration will sharpen your focus on exam day.
培养积极的心态——你已经做了充分准备。冷静读题，管理好时间，相信复习的成果。充足的睡眠和适量饮水能让你在考试当天思维清晰。
Good luck with your
