1. Sorting: Sort the wrong questions according to the question type, knowledge point or difficulty, which is convenient for follow-up review and intensive training.

2. Mark the reasons: mark the wrong reasons next to the wrong questions, such as conceptual understanding errors, calculation errors, unclear problem-solving ideas, etc. This will help to find out your weakness.

3. Analysis of problem-solving ideas: carefully analyze the problem-solving ideas of wrong questions and find out the mistakes or deficiencies in the problem-solving process in order to improve.

4. Summarize the law: for a class of wrong questions, summarize the law and problem-solving skills, form a problem-solving template or method, and improve the problem-solving efficiency.

5. Do more similar questions: After sorting out the wrong questions, do more similar questions, consolidate knowledge points and problem-solving skills, and avoid making the same mistakes again.

6. Review regularly: review the wrong questions regularly, deepen the understanding and memory of knowledge points, and also test your progress and mastery.

7. Ask for help: For some difficult or wrong questions that you don't understand, you can ask teachers, classmates or parents for help and answers to deepen your understanding of knowledge.

In short, when sorting out math mistakes, we need to be systematic and targeted, pay attention to analysis and summary, and improve our math ability and problem-solving level through constant practice and review.
