Taking mathematics as an example, I don't think it is necessary to sort out all the wrong questions. Some wrong questions that you think are just mistakes or carelessness don't need to be sorted out. The most important thing to sort out is the common frequently asked questions that you can't master at all. If it is too difficult, you can choose it according to your own level.
What is the main goal of the wrong question? Check for leaks and fill the gaps! In my opinion, many wrong questions are mainly due to lack of knowledge, confusion of thinking or ignorance of some problem-solving methods, and more importantly, the lack of some knowledge points.
So sorting out the wrong questions is divided into three steps:
1, understand the problem-solving breakthrough of wrong questions, and focus on marking papers.
It is how to solve this problem and how to think that it can be solved in this way. This idea is very important.
2. Copy the questions by yourself and do it again cleanly.
When the teacher speaks, you may suddenly realize that this is the case, but in fact, if you don't pay attention to what the starting point is, and secondly, you just follow the teacher's ideas, it is easy to repeat the same mistakes when you meet again. Therefore, it is a process of independent thinking and reflection for a person to repeatedly do wrong questions, which will deepen your understanding and memory. That is to say, I have a deeper understanding of the topic and a deeper memory of the problem-solving ideas.
By the way, if you don't want to copy the questions by hand, you can download an APP called "Wrong Book" to avoid copying by hand, and you can also organize it into a Word document, which can improve the efficiency of sorting out your wrong questions.
3. Take it out again and again from time to time to review the past and learn new things.
If the wrong question is just wrong, put it down if you change it, then you are basically doing nothing! Because it's easy to forget things that you don't know much about. Repetition is a stupid method, but it is a scientific method.
