For preview, it is mainly to read quickly and understand quickly. The most important thing is to overcome internal and external interference. External interference includes irrelevant sounds, distracting visual and olfactory stimuli, etc. Internal interference mainly refers to fatigue, illness, thoughts and feelings unrelated to study, etc. To overcome the internal interference, we should actively exercise, ensure adequate sleep, intentionally change the learning content, avoid excessive brain use and prevent physical and mental fatigue. To overcome external interference, we should try to avoid external stimuli that affect our attention, such as putting away irrelevant picture toys on the table and turning off the radio. We should also consciously exercise our will, cultivate the ability of "seeking peace in a difficult situation", and keep our attention always flexible.

For review, it is mainly to improve the speed of doing the questions. No matter how people criticize "sea tactics" nowadays, I think it is essential to do problems in mathematics and physics, which is a process of combining what we have learned with specific operations, so it is necessary to do problems in the study of mathematics and physics. But doing problems does not mean doing them together. I think it's not very expensive to do the problem. Learn to "draw inferences from one instance" when doing problems, and try to figure out the characteristics of such problems with your heart. This is a good way to improve the speed of doing problems. At the same time, it should be noted that every time you do a problem, you must learn something from it. If we can't do ten unproductive problems, we will still do this one. Where does this gain come from? Is to summarize and classify. Find the * * * relationship between different types of questions and different knowledge points, and systematize the knowledge learned.

In addition to preview and review, I think there is another point that needs to be mentioned, that is, attending classes. Try to learn to understand this part of the content when the teacher is giving a lecture, otherwise it will take a lot of time and energy to study by yourself after class, and you may not learn well. Attending classes is the most important part. It's a pity that students spend most of their time in class, so much time is useless. High efficiency in class can not only save review time, but also greatly help you improve the speed of doing problems. At the same time, targeted exercises after class must be done seriously and not lazy. You can also calculate the classroom examples several times when reviewing after class. After all, in class, the teacher is calculating and explaining problems, and the students are listening. This is a relatively mechanical and passive process of accepting knowledge. Maybe you think you understand it in class, but in fact, your understanding of problem-solving methods has not reached a deeper level, and it is very easy to ignore some difficulties that will inevitably be encountered in the real problem-solving process. "A good brain is better than a written one." For solving mathematical and physical problems, it is not enough to rely only on the general ideas in the brain. Only through careful written calculation can we find the difficulties, master the solutions and finally get the correct calculation results.
