📚 No Method Shown: AQA A-Level Maths Method Marks | 没有展示方法：AQA A-Level 数学中的方法分
In AQA A-Level Mathematics, writing down only a final answer is a dangerous habit. Many questions carry method marks that are awarded for the process, not just the result. If no method is shown, examiners often cannot award those marks, even when the final answer is correct.
在 AQA A-Level 数学考试中，只写最终答案是一个危险的习惯。许多题目都包含方法分，这些分数是给解题过程而不是只看结果。如果没有展示方法，即使最终答案正确，考官通常也无法给出这些方法分。
1. How AQA Marks a Solution | AQA 如何给解答打分
Every AQA mark scheme divides marks into three main types: M marks for method, A marks for accuracy, and B marks for independent facts or statements. Method marks reward you for choosing a correct route and carrying it out, even if a small slip occurs later.
每份 AQA 评分方案都把分数分为三大类：M 分代表方法，A 分代表准确性，B 分代表独立的事实或陈述。方法分奖励你选择正确路径并执行它，即使后面出现小错误。
ting a standard formula such as ∫xⁿ dx = xⁿ⁺¹/(n+1) without being asked can earn a B mark.
例如，在一道微分题中，使用乘法法则可能获得一个 M 分。最终导数正确获得 A 分。写出标准公式如 ∫xⁿ dx = xⁿ⁺¹/(n+1) 且题目未要求时，可能获得 B 分。
2. What "No Method Shown" Really Means | "没有展示方法" 真正意味着什么
When a candidate writes only an answer, the examiner must judge whether any method is implied. If the method cannot be inferred clearly, the mark scheme usually states that no M marks should be awarded. Correct final answers may still earn A or B marks, but the process credit is lost.
当考生只写一个答案时，考官必须判断是否能推断出任何方法。如果方法无法被清晰推断出来，评分方案通常规定不应给 M 分。正确的最终答案可能仍会得到 A 分或 B 分，但过程分就丢了。
This is especially true when the mark scheme says "award M1 for ..." and the candidate has not shown that step. Writing the final answer
