How to sort out the wrong problems in mathematics

(1) To make a mistake, you must first make clear your goals and correct your attitude. We didn't make a mistake for formalism. Moreover, if you want to make a mistake, you must stick to it and don't give up halfway. I think it will be a wonderful memory when we finish our studies.

2 First, predict the mistakes that you are likely to make in recent years, choose a thick notebook, and pursue the quality of the notebook instead of gorgeous;

3 when extracting the wrong questions, don't blindly extract them. Because of carelessness or miscalculation, it is best not to extract them. Because the wrong questions need to be simplified;

(4) typesetting should be clear, wrong questions should be numbered, and the grade should be indicated. It's best to distinguish questions and answers with pens of different colors. If necessary, extended knowledge such as formulas and theorems can be prominently expressed.

This is extra. Landlord, you might as well search for more difficult questions in your spare time. We must guard against the difficult problems on the examination paper.

I suggest you pay special attention to the wrong questions in science.
