Experience 1: 1, you might as well set yourself some time limits. It's easy to get tired of studying for a long time. At this time, you can divide your homework into several parts and limit the time of each part, for example, finish this exercise within one hour and finish that test before eight o'clock. This will not only help to improve efficiency, but also avoid fatigue. If possible, gradually shorten the time used, and soon you will find that the homework that you couldn't finish in an hour before is now finished in 40 minutes. 2. Don't do other things or think about other things while studying. Everyone knows that you can't do two things at once, but there are still many students who listen to music while studying. Maybe you will say that listening to music is a good way to relax your nerves, so you can concentrate on studying for an hour and then relax listening to music for a quarter of an hour, which is much better than doing your homework with headphones on. Don't review the same lesson all night. I used to spend an evening watching math or physics. Practice has proved that it is not only easy to get tired, but also has a poor effect. Later, I arranged to review two or three classes every night, and the situation was much better. You don't need to take detailed notes in class except for very important content. Busy taking notes in class will be inefficient, and there is no guarantee that you will take notes after class. The main work in class should be to digest and absorb the teacher's lecture content and make some brief notes appropriately. Lesson 2: I have also talked to many people about learning efficiency. We often see such a situation: a classmate studies very hard, studying at school, studying at home, sometimes staying up late and doing countless problems, but his grades are always not up. In fact, I am also very anxious in the face of such a situation. Originally, what you paid should be rewarded. Moreover, if you pay more, you should get a lot of rewards. This is a natural thing. But this is not the case. There is an efficiency problem here. What does efficiency mean? Just like learning, some people will practice it ten times, while others need to practice it a hundred times. There is an efficiency problem. How to improve learning efficiency? I think the most important thing is to combine work and rest. What is most needed to improve learning efficiency is a clear and agile mind, so proper rest and entertainment is not only beneficial, but also necessary, which is the basis of improving learning efficiency. So how to improve the efficiency of class? In my experience, it is necessary to preview before class, but my preview is rough, and I only glance at the teaching materials, so that the contents and key points of the teaching materials are roughly in my mind and I can be more targeted when I attend classes. When we preview, we don't need to be too detailed. If we are too detailed, it is a waste of time. Second, I will be a little lax in class, and sometimes I will ignore the most useful things. It is of course necessary to listen carefully in class, but as one of my former teachers said, no one can concentrate in a class, which means it is impossible to concentrate for more than 40 minutes, so there is also a problem of time allocation in class. Teachers can relax when they talk about familiar things. In addition, taking notes sometimes hinders the efficiency of class. Sometimes a class is busy copying notes, and sometimes some very important things are ignored, but this does not mean that you can not take notes, which is not enough. Everyone will forget that with notes, there will be a basis for review. Sometimes the teacher talks a lot and writes a lot on the blackboard, but you don't need to remember them all. Of course, you should remember some books. Otherwise, remember what you see, which will inevitably affect the efficiency of class, and the loss will outweigh the gain.
