1. Sort out, analyze and classify the wrong questions in the usual exercises or exams, and analyze the causes of the mistakes, and make it clear whether they are wrong answers, wrong thinking methods, wrong knowledge, wrong operation, etc. , is the key step to establish the wrong question set.

2. The wrong questions should be sorted out in a targeted manner. Not all the wrong questions should be sorted out. For some mistakes in memory and some mistakes caused by exam-taking skills, we should correct them in the test paper or homework paper. It is necessary to focus on combing the test sites at the level of "understanding and application", knowledge points with strong regularity and methodology, and knowledge points that are easy to make mistakes and block thinking.

3. Pay attention to the accumulation of methods. The wrong question set is not a simple wrong question. We should pay attention to the diagnosis of the causes of wrong questions, the teacher's analysis and explanation of wrong questions, the introduction of questions, the breakthrough point of solving problems, the breakthrough method of thinking, the skills of solving problems, the steps and summary of standardization, etc. And annotate the wrong questions, write down the thinking process when solving the problems, and expose the analysis of the causes and roots of the mistakes.

4. For the wrong questions in the "wrong question set", you must also look for materials or teaching materials, find out the same or related questions, and make answers to ensure that you master this knowledge point. At the same time, you can also try to adapt the wrong questions.

5. Bind the "wrong problem set" according to your own style, number pages, and suggest loose-leaf binding for timely replacement or supplement.

Finally, you must make full use of your wrong problem set. Usually, we should not only pay attention to sorting out and summarizing in time, but also read more books and reflect more; Although each student's "wrong question set" is different, the advantages of other students' "wrong question set" can be used for reference, so we should also pay attention to mutual communication at ordinary times.
