How to learn junior high school mathematics and physical chemistry well, and find the answer.
Physics, a natural science course, is difficult to learn, and it is impossible to learn by rote. So, how to learn physics well? Personally, I think that to learn physics well, we should do the following:

(1) Do the problem independently. Do some problems independently with good quality and quantity (meaning not relying on others). There must be a certain number of topics, not too few, but also a certain quality, that is to say, there must be some difficulty. Anyone who studies mathematics and physics can't learn this level well. Solving problems independently may sometimes be slow, sometimes you have to take detours, and sometimes you can't even solve them, but these are normal and the only way for any beginner to succeed.

(2) attending classes. Listen carefully in class and don't think or think as little as possible. Don't be self-righteous, learn from the teacher modestly. Don't give up listening just because the teacher speaks simply. If this happens, it can be regarded as review and consolidation. Try to be consistent and synchronized with the teacher, and you can't do it yourself, otherwise it will be self-study. After getting started, with a certain foundation, you are allowed to have your own activity space, that is, you are allowed to have something of your own. The more you learn, the more things you have.

(3) notebooks. Class is mainly based on listening, and there are notebooks, and some things should be written down. Knowledge structure, good problem-solving methods, good examples, places you don't understand, etc. Should be recorded. After class, you should organize your notes. On the one hand, you should "digest" and on the other hand, you should supplement your notes. Notebook is not only to remember what the teacher said in class, but also to make some reading notes. Good problems found in homework and good solutions should also be recorded in a notebook, which is what students often call a "good problem book". Hard-won notebooks should be numbered, studied later and kept for life.

(4) learning materials. Learning materials should be well preserved, classified and marked. The classification of learning materials includes exercises, papers, experimental reports and so on. Marking refers to, for example, marking exercises. General questions are not marked. Good questions, valuable questions and error-prone questions are marked differently for future reading. Marking can save a lot of time.

(5) time. Time is precious. Without time, there is no time to do anything, so we should pay attention to making full use of time, which is a very superb art. For example, we can save time by "recalling" learning methods. Before going to bed, waiting for the bus, walking on the road, etc. We can recall the lessons of the day section by section, so that we can learn them again and again and achieve the goal of strengthening. Some physics problems are more difficult, and some problems may be solved on foot. People who study physics often have several problems in their minds that they can't do and won't forget. I don't know when they will make a breakthrough and find the answer to the question. (8) learn from others. We should learn from others, from our classmates, from people around us and see how others learn. We should often have "academic" exchanges with them, teach each other, learn from each other and improve together. We must never be self-righteous. Cann't be conservative Tell others if you have a good method, so that others will tell you that you have a good method. You should have some good friends in your study.

(6) mathematics. The calculation of physics depends on mathematics, which is too important for learning physics. Physics is difficult to do without mathematics as a calculation tool. In the physics department of the university, mathematics and physics are equally important. To learn mathematics well, we must make good use of this powerful tool.
