First of all, I am very opposed to the views upstairs. I have never used the wrong problem set, but I am not bad at math. I always think that learning is a problem of understanding, especially in science. Mathematics is the foundation of science and needs a good understanding. Wrong questions are not necessarily valuable and can help us understand, but most of them are caused by carelessness or momentary thoughts. If you can understand them, but I don't agree with the method of collecting the wrong questions together. The reason is nothing more than to watch them in the future and prevent similar situations from happening again. But is it really useful? It is valuable for us to correct and understand a wrong question as soon as possible after doing it wrong. After a while, if we look at it again, it seems that the influence has deepened, but it may be completely gone, and the value it brings to us will also decrease. However, if we go back and forth in this way, we will spend a lot of time doing a repetitive thing, but it is of no value, so the efficiency will be low, and it will widen the gap with others, and we will get less reward if we pay more, which is what everyone does not want, so the wrong set of questions will not bring us many benefits.
Besides, high school life is very tense, and there is not much time to read the wrong questions. Mainly think more, think more. Moreover, the purpose of our study is not to do the problem, so it is impossible to understand and record the problem. As long as we remember the knowledge well and understand it thoroughly, even if a question is wrong, we just need to understand it, and there is no need to record it at all.
Moreover, I found a feature in my life. The best students learn with pens (that is, they record a lot of things and spend a lot of time), but only a few can do it in one class. They are followed by people who use their brains to learn. They think that their grades are not the best, but they are easy to learn, and their grades are in front of the whole class. From time to time, their grades will be greatly improved, because their grades are generally caused by mistakes. Once they are careful, the consequences can be imagined. It can be seen that the result of thinking is not the first, but much happier than the first.
I've said a little too much. I just want to tell you, first of all, the wrong set of questions has little practical effect. I just lied to myself and told myself that I was working hard, but I actually wasted a lot of time.
But if you have a poor foundation, I suggest that you can record some typical questions with the wrong set of questions, which will help you score with a poor foundation, but if you have a good foundation, don't use the wrong set of questions.
