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 something very important is 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. How to improve the efficiency of doing problems? The most important thing is to choose a "good topic" and never do it indiscriminately. In that case, it will often get twice the result with half the effort. The questions are all around knowledge points, and many questions are quite similar. First, choose the knowledge point you want to strengthen, and then choose the questions around this knowledge point. There are not many problems. Just a similar question is enough. After choosing the topic, you can do it seriously. The improvement of problem efficiency largely depends on the process after the problem is solved. For the wrong question, we should seriously think about the cause of the error, whether it is because the knowledge points are unclear or careless. After the analysis, do it again to deepen the impression, so that the efficiency of doing the problem will be much higher. Comments: Yu Xia's suggestion on attending lectures and doing problems actually reflects an important method to improve learning efficiency-"keeping your strength on the cutting edge", that is, allocating time reasonably, paying attention to key points when attending lectures and taking notes, and grasping typical examples when doing problems, which is "getting twice the result with half the effort" in learning. Experience 3: Learning efficiency is an important factor in determining academic performance. So, how can we improve learning efficiency? First, confidence. Many scientific studies have proved that human potential is great, but most people have not effectively developed this potential. Among them, people's confidence is a very important aspect. No matter when and where you do anything, with this confidence, you will have the belief of winning, and you will soon get rid of the shadow of failure. On the contrary, if a person loses self-confidence, he will accomplish nothing, and it is easy to fall into eternal inferiority. Another important means to improve learning efficiency is to learn to concentrate. The process of learning should be a process of thinking with the brain. Whether you look with your eyes, read with your mouth, or copy by hand, they are all means to help your brain. The real key is to think with your head. Give a very simple example, such as memorizing words. If you just browse or copy aimlessly, it may take many times to remember, and it is not easy to remember. But if you can give full play to your imagination and use the method of association to remember, you can often remember quickly and not easily forget. Nowadays, the method of memorizing English words quickly introduced in many books also emphasizes the role of brain association.

It's good. Trust you. ..
