📚 Year 8 WJEC Maths: Exam Techniques and Marking Criteria | Year 8 WJEC 数学：答题技巧与评分标准
Success in Year 8 WJEC maths exams relies not only on knowing the content but also on understanding how marks are awarded and applying effective exam techniques.
在 Year 8 WJEC 数学考试中取得好成绩不仅依赖于掌握知识点，还需要理解评分标准并运用有效的答题技巧。
1. Understanding the Mark Scheme | 理解评分方案
WJEC exam papers are marked using a detailed mark scheme that awards method marks (M), accuracy marks (A), and sometimes independent marks (B).
WJEC 试卷采用详细的评分标准进行评阅，其中包含方法分（M）、准确性分（A），有时还有独立分（B）。
| Mark Type | Description |
| M (Method) | Awarded for showing a correct step or process, even if the final answer is wrong. |
| A (Accuracy) | Awarded for obtaining the correct answer, usually dependent on method marks first. |
| B (Independent) | Given for stating a correct fact or drawing a correct diagram, without needing to show working. |
Many students lose marks because they skip steps and the examiner cannot see the method.
许多学生因为没有充分展示解题步骤，导致阅卷老师无法判断方法而失分。
Always write down your working, even for simple calculations, to secure valuable method marks.
即使是简单的计算，也务必写下解题过程，以确保获得宝贵的方法分。
2. Showing Working for Method Marks | 展示步骤以获得方法分
Method marks are the safety net. If you make a small arithmetic slip but your approach is correct, you will still earn most of the marks.
方法分是安全网。即使你犯了一个小的计算错误，只要解题思路正确，你仍然能获得大部分分数。
For example, when solving 3x + 5 = 20, you should write: 3x = 20 – 5, so 3x = 15, then x = 5. Do not just write x = 5.
例如，解方程 3x + 5 = 20 时，你应该写出：3x = 20 – 5，得出 3x = 15，然后 x = 5。不要只写 x = 5。Published by TutorHao | Year 8 Mathematics Revision Series | aleveler.com
