As the saying goes, "Learn mathematics and physics well and travel all over the world". Mathematics, physics and chemistry in senior high school is the highlight. How can we learn these three subjects well and even make them a magic weapon for you to excel? Mathematics Mathematics seems to be the subject that needs least memory, but it is not easy to use it flexibly. Yue Fei's "The Art of War" said that "the cleverness of strategic planning lies in one heart". If we can connect the whole series of subjects with this content, it will be the first step to success. Except for a few particularly smart people, a considerable number of exercises must be done to learn this course well. So how to deal with the relationship between learning and studying book knowledge and doing exercises in series? As far as my personal experience is concerned, in any case, we must pay enough attention to the relationship between basic knowledge and knowledge, learn to review what we have learned consciously when doing exercises again, and it is particularly important to consolidate and find out the relationship between knowledge. If we can form a clear concept, supplemented by a certain amount of practice, we can reach a considerable level. On the other hand, if you don't know how to summarize the problem, the efficiency of doing it will be greatly reduced. Physical physics is a rich subject, which not only uses logical and mathematical abilities such as reasoning and calculation, but also seeks knowledge from the outside world through observation and experiment. Therefore, this course plays a great role in improving people's scientific literacy, and it is not a studious course for a considerable number of students. Another obvious feature of this course is that it is divided into several relatively independent parts, such as force, heat, electromagnetism, light and atom, and each part has its own set of corresponding learning methods. If you are good at separation and division, it will help to clarify the concept and be more efficient. There are systematic knowledge about physics, such as statics and dynamics, which are quite perfect theoretical systems, but there are also scattered knowledge, such as atomic physics. The knowledge of the corresponding system should be based on understanding, and its content should be deeply understood; And for scattered knowledge, perhaps the effort of memory is more important. Physics books mainly give some basic concepts and theories. In order to cope with the difficult and flexible college entrance examination questions, it is very important to do quite a few exercises, deepen the knowledge learned in the process of doing the questions and form a problem-solving routine for a class of questions. In my impression, chemical chemistry is a relatively scattered subject, and there are some basic theories, but they all seem to be scattered knowledge points, which are not systematic enough to bring some trouble to learning. Moreover, although the basic theory of chemistry is not very complicated, it is not easy to apply it freely. This requires us to study the basic theory in the textbook seriously, supplemented by high-quality exercises, study hard and understand effectively; For all the knowledge points mentioned in the book, we should try our best to master them comprehensively and should not miss anything. In addition, it is particularly important to point out the experimental problems in physics and chemistry. Experimental questions are very important in the college entrance examination. Fortunately, there are not many typical experiments of physical chemistry, or there are not many experiments that are rich in content and easy to get. It is best to effectively master and understand all kinds of subtle knowledge points involving theory and practical operation.
