📚 Year 11 CIE Mathematics: Exam Techniques and Marking Criteria | Year 11 CIE 数学：答题技巧与评分标准
Mastering the content is only half the battle in CIE IGCSE Mathematics. To convert your knowledge into top marks, you must understand exactly how examiners award scores and adopt smart exam techniques. This guide walks you through the marking criteria and strategies needed to maximise your grade.
掌握知识只是 CIE IGCSE 数学成功的一半。要将其转化为高分，你必须确切地了解考官如何给分，并采用聪明的考试技巧。本指南将带你了解评分标准以及最大化分数的策略。
1. Understanding the Exam Structure | 了解考试结构
The CIE IGCSE Mathematics (0580) syllabus offers two routes: Core (Grades C–G) and Extended (Grades A*–E). Core candidates sit Paper 1 (1 hour, non‑calculator) and Paper 3 (2 hours, calculator). Extended candidates sit Paper 2 (1 hour 30 minutes, non‑calculator) and Paper 4 (2 hours 30 minutes, calculator). Knowing the duration, number of questions and whether a calculator is allowed helps you plan your revision and time on the day.
CIE IGCSE 数学（0580）考纲提供两条路径：核心（C–G 级）和扩展（A*–E 级）。核心考生参加 Paper 1（1小时，无计算器）和 Paper 3（2小时，可使用计算器）。扩展考生参加 Paper 2（1小时30分钟，无计算器）和 Paper 4（2小时30分钟，可使用计算器）。了解时长、题目数量以及是否允许使用计算器有助于你规划复习和考试当天的时间。
Each paper tests different skills: the non‑calculator paper emphasizes mental arithmetic, estimation and algebraic manipulation, while the calculator paper includes problems requiring complex calculations, trigonometry and statistical analysis. Always check the front of the paper for specific instructions about rounding and acceptable formats.
每份试卷考察不同的技能：无计算器试卷强调心算、估算和代数运算，而计算器试卷则包含需要复杂计算、三角学和统计分析的问题。务必检查试卷首页关于舍入和可接受格式的具体说明。
2. The Importance of Showing Working | 展示解题步骤的重要性
Examiners do not just look at the final answer. They need to see the steps that led to it. Clear method earns method marks even if the final answer is wrong due to a slip. For example, in solving 3x + 5 = 20, writing ‘3x = 15’ and then ‘x = 5’ shows the correct method and earns full marks. If you miscalculate and write x = 4, you can still receive the mark for the correct first step.
考官看的不仅仅是最终答案。他们需要看到导致答案的步骤。清晰的解答过程能赢得方法分，即使最终答案因为小失误而错误。例如，解 3x + 5 = 20 时，写出 ‘3x = 15’ 然后 ‘x = 5’ 展示了正确的方法并获得全部分数。如果你计算错误写成 x = 4，你仍然可以获得第一步正确的方法分。
In questions with higher mark allocations, such as 4‑ or 5‑mark questions, you must break down the problem into logical stages. Crossed‑out work is still marked, so never obliterate a method you think is wrong; simply draw a single line through it if you change your mind.
在分值较高的问题中，如 4 分或 5 分题，你必须将问题分解成逻辑步骤。划掉的工作仍会被评分，所以如果改变主意，只需用单线划掉你认为错误的部分，切勿完全涂黑。
3. Method Marks and Accuracy Marks | 方法分与答案分
CIE mark schemes use several types of marks. The most common are:
M marks – awarded for knowing and applying a correct method.
A marks – awarded for accuracy of the answer, often dependent on obtaining a correct result from the previous step.
B marks – independent accuracy marks, earned for a correct result without any method shown, or for a specific statement such as identifying a coordinate on a graph.
CIE 评分方案使用几种类型的分数。最常见的有：
M 分 – 因知道并运用正确方法而得分。
A 分 – 因答案准确性而得分，通常取决于从上一步得出正确结果。
B 分 – 独立准确性分，无需展示方法即可获得正确答案，或如识别图形上的坐标等特定陈述。
The following table illustrates how these are applied in a typical algebra question:
下表展示了这些分数在一个典型代数题中的应用：
| Step | Work | Mark type |
|---|---|---|
| 1 | 2(x – 3) = 8 → 2x – 6 = 8 | M1 – expanding brackets |
| 2 | 2x = 14 | A1 – correct simplification |
| 3 | x = 7 | A1 – final answer |
If you make a sign error in step 2 but continue correctly, you might still earn M1 and an ‘ft’ (follow‑through) mark for step 3 if the error is not conceptually severe. This is why showing each stage matters.
如果你在步骤2犯了符号错误但继续正确作答，如果错误不严重，你可能仍能获得 M1 分以及根据错误后续得出的 ‘ft’（跟随）分。这就是为什么展示每个阶段至关重要。
4. Using Correct Notation and Units | 使用正确的符号和单位
Mathematical language must be precise. When working with inequalities, use ≥ or ≤ instead of words. For coordinates, always write (x, y) with the x‑value first. In geometry, label angles with three letters, e.g. ∠ABC, or use a variable like θ. Failure to do so can lose B marks that require exact notation.
数学语言必须精确。处理不等式时，使用 ≥ 或 ≤ 而不是文字。表示坐标时，始终写成 (x, y)，x值在前。在几何中，用三个字母标记角，如 ∠ABC，或使用变量如 θ。不这样做可能会丢失要求精确符号的 B 分。
Units are equally important. If a question gives measurements in centimetres and you leave the answer as a bare number, or if the answer requires m² but you write cm², you may lose the final accuracy mark. Always copy the unit given in the question unless asked to convert.
单位同等重要。如果题目给出的测量单位是厘米，而你的答案没有带单位，或者题目要求平方米你却写了平方厘米，你可能会失去最后的准确性分。除非要求换算，否则始终照抄题目给定的单位。
In the calculator paper, answers should be given to 3 significant figures unless the question states otherwise, but exact values like π or √2 can be left in simplified radical form. For money questions, give your answer to 2 decimal places.
在计算器试卷中，除非题目另有说明，答案应给出 3 位有效数字，但像 π 或 √2 这样的精确值可以保留为简化根式。涉及金钱的问题，答案要给出两位小数。
5. Common Pitfalls in Algebra and Graphs | 代数和图形中的常见陷阱
Many marks are lost through careless algebra. For instance, when solving a quadratic by factorising, you must set the expression to zero first. Writing (x + 2)(x – 3) is not enough; you need (x + 2)(x – 3) = 0 and then x = –2 or x = 3. Missing the ‘= 0’ step loses the method mark.
许多分数因粗心的代数运算而丢失。例如，通过因式分解解二次方程时，你必须先将表达式设为零。只写 (x + 2)(x – 3) 是不够的；你需要写 (x + 2)(x – 3) = 0，然后得出 x = –2 或 x = 3。忽略“= 0”这一步会失去方法分。
When plotting graphs, students often forget to join points with a smooth curve instead of straight segments. For trigonometric graphs, the shape, stationary points and intercepts must be clearly labelled. Graph questions always carry an accuracy mark for a fully correct curve and a ‘B’ mark for plotting enough correct points.
绘制图形时，学生经常忘记用平滑曲线连接点，而是用直线段。对于三角函数的图形，必须清晰标记形状、驻点和截距。图形题一定包含一个完全正确曲线的准确性分，以及一个绘制足够正确点的 ‘B’ 分。
Also, watch out for the ‘=’ sign use in multi‑step equations. Every line should be equivalent to the line above; inserting an extra ‘=’ where it does not belong, such as ‘3x + 2 = 8 = 3x = 6’, is incorrect mathematically and can cause confusion.
此外，注意等号在多步方程中的使用。每一行应与上一行等价；在不该出现的地方插入额外等号，例如 ‘3x + 2 = 8 = 3x = 6’，在数学上是不正确的，会造成混淆。
6. Time Management Strategies | 时间管理策略
A common reason for underperforming in CIE Maths is running out of time. The total mark for each paper is printed on the front page; use it to allocate time. As a rough guide, spend about 1 minute per mark. For example, on Extended Paper 4 (130 marks in 150 minutes), you have just over a minute per mark. Stick to this pace and move on if stuck.
CIE 数学考试表现不佳的一个常见原因就是时间不够。每份试卷的总分印在首页上；利用它来分配时间。作为粗略指导，每 1 分花大约 1 分钟。例如，扩展 Paper 4（150 分钟 130 分），你每分有略多于 1 分钟的时间。保持这个节奏，如果卡住了就先往下做。
