Mathematics is a subject that many people like, because it is easy to get full marks as long as they understand the train of thought, but some people are very worried, and many people have scored 20 or 30 points. Many students have this feeling when doing math problems, that is, they can understand an exercise by looking at the answer, but when they do it themselves, they are blank and don't know where to start. In fact, the answer we read is not our own way of solving problems, but others'. Just because you read it doesn't mean you have studied it, so you still don't understand.

One: Do it again by yourself. Want to change this situation, can't just look at the answer. You must do it again by yourself and see if you can do it from the beginning. Only the questions you have really thought about and understood will be impressive. If you just look at the answer and think you can understand it, you will find that you still can't do it again, and your impression is very vague.

Two: find the same type of exercises to practice. Secondly, we should find the same type of exercises to practice. There are so many knowledge points in mathematics that the exercises are all extended through the knowledge points. It can be said that everything changes. As long as you understand the same type of questions, then this knowledge point can be more consolidated and practical, and it can be more fresh and clear when we meet again in the future.

Three: Develop the habit of thinking by yourself. When doing math problems, we should form the habit of thinking. Thinking is very important. Why do some people get full marks without attending classes, and some people just pass when they die? People understand thoroughly and can deal with any problems. They can only do this one, but they won't if they change the subject, so they naturally fail the grade. I must first analyze how to do it, think about it and calculate the result. If I can't answer every question, I won't study.

In mathematics, you said that it is difficult for people to get full marks, and you said that some people can easily get only 20 or 30 points. The key lies in one's learning ability, and only when one really understands it can one improve one's math performance.
