2021年1月进阶数学第四单元的评分方案远不止一份答案，它是窥探阅卷官思维的窗口。通过研究过程分、答案分和推理分如何分配，你可以彻底改变解题方式并锁定高分。本文深度解读该评分方案的关键启示，并将其转化为可操作的高分技巧，助你在复习和模考中脱颖而出。
1. Decoding Mark Types | 解读评分分数类型
The mark scheme categorises scores into ‘M’ (method), ‘A’ (accuracy), and ‘B’ (independent) marks. ‘M’ marks reward using a valid mathematical approach even if the final answer is incorrect. ‘A’ marks depend on correct computation following a correct method. Understanding this hierarchy helps you prioritise showing all necessary steps.
评分方案将得分分为M分（方法分）、A分（准确度分）和B分（独立分）。M分奖励使用有效数学方法的行为，即使最终答案错误。A分依赖于正确方法后得出的准确计算。弄清这种层级关系能帮助你优先展示所有必要步骤。
| Mark Type | Meaning | Action for You |
|---|---|---|
| M | Method mark | Show clear working steps |
| A | Accuracy mark | Double-check arithmetic |
| B | Independent mark | State definitions directly |
