You should change the revised edition regularly, because it needs to be used. It will be updated when it is finished. If it is wrong, continue to add the wrong version, otherwise delete it, which can simplify the version, save time and improve efficiency.

The following practices:

1. Prepare a thick notebook, which is the wrong book. Don't buy fancy ones in the market, just use a notebook, just a little thicker.

2. When encountering a wrong problem, write it in the wrong problem book, the stem of the problem and the solution of the wrong problem are written in black, the relevant fuzzy formula knowledge is written in red+positive solution process, and the key places are specially marked.

3. After learning a chapter, come to a wrong topic summary meeting to see which pits you will fall into in this chapter, and form a framed wrong topic summary to avoid in the future.

4. Show your wrong problem book to the math teacher and let the teacher show you the way from the side. It depends on the master.

5. Sort out the wrong questions in the test paper separately, use post-it notes with different colors to help classify, analyze the results and reasons for gains and losses, and sort out the wrong questions in a separate folder. If it is a little troublesome to cut the test papers, compile them separately, especially when there are many test papers in junior and senior high schools. This is more practical.

It is a very good method and habit to sort out the wrong questions in science, especially mathematics. Let's talk about several sorting methods of wrong questions:

1: Copying is suitable for students who have less wrong questions and time. After copying it, they will do it again. It is generally suitable for sorting once a week. Remember to keep a copy for the second wrong exercise.

2. Shooting printing method is suitable for students who have printers with wrong questions at home, which is convenient, fast and costly.

3. Cut and paste the wrong questions directly in the wrong book, which is suitable for non-double-sided. Cut and paste directly in the wrong book, and then practice the wrong questions in the blank.

4. Nail the test papers and exercises with wrong questions directly, and only read the wrong questions at a time, which is the most time-saving, but it is not convenient for centralized viewing. We should use the wrong book to analyze the types of wrong questions, find the weak points, causes and solutions of wrong questions, and truly achieve the purpose of sorting out wrong questions.
