The investigation of mathematics is mainly the basic knowledge, and the difficult problems are only synthesized on the basis of simple problems. So the content in the textbook is very important. If you can't master all the knowledge in the textbook, you won't have the capital to learn by analogy.

1, it is best to preview the contents in the textbook before class. After class, we must do targeted exercises seriously and not be lazy. You can also calculate the classroom examples several times when reviewing after class. After all, you should take good notes in class. Good memory is not as good as writing. For solving mathematical and physical problems, it is not enough to rely only on the general ideas in the mind. Only through careful written calculation can we find the difficulties, master the solutions and finally get the correct calculation results.

2. Secondly, we should be good at summarizing and classifying, looking for the * * * relationship between different types of questions and different knowledge points, and systematizing what we have learned.

Finally, we should strengthen after-class exercises. Besides homework, find a good reference book and do as many exercises as possible (especially comprehensive and applied questions). Practice makes perfect, thus consolidating the effect of classroom learning and making your problem solving faster and faster.
