1. Understanding is more about grasping preview, attending lectures and reviewing tightly, and understanding what you have learned from multiple levels and angles. Preview can be divided into rough reading and intensive reading. Take a cursory look at what you want to learn first, and circle the important parts in the form of subtitles. Then read the circled part carefully and have a deep understanding, that is, intensive reading. In class, you can listen to the teacher explain the difficult points and answer questions purposefully. Only in this way can we understand knowledge more comprehensively and thoroughly. In after-class review, in addition to understanding and memorizing formula theorems, we should also deeply understand the teacher's lecture ideas and the "central idea" of solving problems, that is, grasping the knowledge points of examples and applying formulas of what theorems to make them orderly and procedural.
2, more practice, not only refers to the practice of consolidating knowledge, but also refers to the "practice" of psychological quality. To consolidate the knowledge, we should not only complete the in-class exercises seriously, but also complete a certain amount of extracurricular exercises. However, simple "sea tactics" is not desirable, and some representative questions should be selected. Students with a good foundation have to do some comprehensive problems and application problems. In addition, we should pay attention to adjusting our mentality on weekdays and cultivate a calm and confident psychological quality.
3. Summarize more. First of all, we should classify and sort out the classroom knowledge in detail, especially the theorem. We should deeply understand its connotation, extension, derivation and scope of application. Summarize the relationship between knowledge points and form a knowledge network in your mind. Secondly, we should analyze and summarize the solutions to various problems. Another kind of summary is also very important, that is, after the usual practice and examination, analyze your own mistakes and weaknesses in order to overcome them in the future.
