First of all, we must understand the purpose of using the wrong book. When we face a wrong problem, we should think about how not to make the same mistake again in the future. Then, record the problem-solving process in the wrong book and read it often to make as few mistakes as possible, thus entering a virtuous circle. Resolutely avoid letting go of mistakes, so that you will find more and more mistakes, enter a vicious circle, and the sense of accomplishment in learning will only get worse and worse. The use of the wrong question book is usually divided into three stages.

First stage

Write down all the wrong questions. Copy down the original question first, sort out the answers and take them out when you have time. This is the first stage. This stage is the most difficult to adhere to. Because I often found the wrong question "useless", I felt that it was a waste of time and gave up in a few days. When I recorded more than ten pages, I turned over the topics recorded in front of me and thought it was too time-consuming to sort out such a simple topic. But to put it another way, if you hadn't recorded these wrong questions and read them often, you might not feel so simple now. This is the most difficult stage for everyone at present, because everyone regards sorting out the wrong questions as a task and doesn't realize that this is a very good way to improve themselves.

stage Ⅱ

Record the wrong questions selectively and record more thoughts. Reflecting on the wrong questions in the first stage, the technical content is too low, which has little influence on the follow-up review and needs to adjust the methods. In order to save time, you can directly tear off the wrong questions and paste them on the book (if you feel torn, it would be a pity to copy all the wrong questions on the book). Don't just write about the process of solving each problem, think about what went wrong at that time, what you learned through the teacher's explanation, and write your own thoughts in a diary (some students complain that you can't write the process, so you just have to write your own thinking process in a composition). For example, "this kind of problem usually takes this as a breakthrough." This stage lasts about a month, and you can really appreciate the benefits brought by the wrong book. In future exams, you won't feel nervous and even expect to find more mistakes. Because these exams are not important, there is no need to show good results to anyone (including yourself) in these exams. For you, the exam is just a process of finding mistakes. After each exercise or exam, spread out the test papers, deal with them one by one, and ask the old teacher if you don't understand anything (the teacher not only teaches you knowledge, but also helps you solve problems).

The third stage

The wrong questions are not limited to sorting out the wrong questions. Sometimes the teacher understands the knowledge points in class and feels very rewarding. After class, we should sort out this knowledge point, sort out related problems and write a few ideas. For example, in mathematics, you can find time to sort out the mistakes, ideas and breakthroughs that the teacher has sorted out. At this time, you will feel that this wrong question is a treasure house. You can't absorb it yourself. When you have time, turn it out and turn it into your own knowledge.
