📚 Year 9 WJEC Mathematics: Exam Techniques and Marking Criteria | 九年级 WJEC 数学：答题技巧与评分标准
Success in Year 9 WJEC Mathematics depends not only on knowing the content but also on understanding how to approach exam questions and how marks are allocated. Familiarising yourself with the marking criteria and adopting effective exam techniques can significantly boost your grade.
在九年级 WJEC 数学考试中取得成功，不仅取决于掌握知识，还取决于理解如何应对试题以及评分是如何分配的。熟悉评分标准并采用有效的答题技巧能显著提升你的成绩。
1. Understanding How Marks Are Awarded | 理解评分方式
WJEC mark schemes use a combination of method (M), accuracy (A) and independent (B) marks. M marks are given for a correct method, A marks for the correct answer following a method, and B marks for stating a fact or answer irrespective of method.
WJEC 评分方案结合了方法分 (M)、准确分 (A) 和独立分 (B)。M 分授予正确的方法，A 分授予方法之后的正确答案，B 分授予独立于方法的陈述或答案。
ou made an arithmetic slip but the method was correct, you would still receive the M1 mark.
例如，解方程 3x + 7 = 22：两边减 7 可获得 M1，然后除以 3 得到 x = 5 可获得 A1。如果你计算失误但方法正确，你仍会得到 M1 分。
Sometimes 'ft' (follow through) marks are allowed, meaning if you use an incorrect earlier answer correctly in a later part, you can still earn marks for that later part.
有时允许使用“ft”（后续）分，即如果你在后续部分正确使用了一个之前错误的答案，你仍可在后续部分得分。
2. Showing Clear Working Out | 展示清晰的解题过程
Always write down your steps, even for simple calculations. Examiners can only award method marks if they can see your working. A blank space or just an answer risks losing all marks if incorrect.
务必写下你的解题步骤，哪怕是简单的计算。考官只有在看到你的解题过程时才能给方法分。留空或只写答案，如果答错就会失去所有分数。
Structure your working logically: state the formula, substitute values, and then solve step-by-step. Even if you get the final answer wrong, clearly shown working can earn most of the marks.
有逻辑地组织解题过程：列出公式，代入数值，然后逐步求解。即使最终答案错误，清晰的解题过程也能获得大部分分数。
In geometry questions, for instance, write down angle facts you use, like 'angles on a straight line sum to 180°'. This demonstrates your reasoning and may earn communication marks.
例如，在几何题中，写下你使用的角度定理，如“直线上的角之和为 180°”。这展示了你的推理过程，可能获得表达分。
3. Method Marks vs. Accuracy Marks | 方法分与准确分
| Mark Type | What It Rewards | Example |
| M1 | A correct step in a method | Subtracting 5 from both sides of an equation |
| A1 | Accurate answer after a method | x = 4 |
| B1 | An independent statement or fact | Giving a definition or reading a value from a graph |
Understanding this difference helps you prioritise. Always attempt a method
