先写原因，不急着抄答案 Write the cause before copying the answer
“这题做错了”只是结果。再往下问一步：是漏掉一个条件、不认识术语、知识点没掌握，还是计算时单位没有统一？先选择最主要的原因；如果暂时找不到，就写“原因待确认”。
“I got it wrong” describes a result. Was the cause a missed condition, an unfamiliar term, a concept gap, or inconsistent units? Choose the main cause. If you do not know yet, write “cause to investigate.”
不要为了把笔记写得完整，就复制整段题干和解析。留下自己真正需要回看的信息，复习时才更容易找到重点。
You do not need to copy a whole question and explanation. Keep the information you actually need to revisit so the next review has a clear focus.
每条记录只留四项 Keep four items in each note
主题：这次练的是什么。错误原因：哪一步出了问题。自己的解释：现在怎样理解。下一步：用什么动作检查是否掌握。
Topic: what you studied. Cause: which step went wrong. Your explanation: how you understand it now. Next action: how you will check that understanding.
答对也可以记，但要说明为什么 A correct answer can still deserve a note
如果这次是猜对的，或者排除两个选项后才蒙中，可以记下“理由还不清楚”。下一次检查的是能否解释思路，而不是还能不能认出原来的选项。
If you guessed correctly or narrowed the choices without understanding the remaining distinction, note that the reasoning is unclear. Next time, check whether you can explain the approach rather than recognize the old option.
下一次复习，从一个动作开始 Begin the next review with one action
打开笔记后，先选一条“下一步”执行。能独立说明，就补上一句新的理解；仍然卡住，再回到相应知识点。不要只把所有笔记从头读到尾，就当作已经复习完成。
Pick one next action from your notes. If you can explain the idea independently, add your updated understanding. If you still struggle, return to the concept. Reading every note from top to bottom is not the same as checking understanding.
在 CACLT PREP 中，可以结合错题与收藏入口安排回看。笔记可写在你习惯的纸本或笔记应用中；这里介绍的是记录方法，不代表平台新增了笔记功能。
Use the mistakes and favorites sections in CACLT PREP to choose what to revisit. Keep notes on paper or in your preferred notes app. This article describes a method, not a new in-platform note-taking feature.
