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. To give a concrete example: in the function part of senior one algebra, we have studied several different types of functions, such as exponential function, logarithmic function, power function, trigonometric function and so on. But comparing and summarizing, you will find that whatever kind of function we need to master is its expression, image shape, parity, increase and decrease and symmetry. Then you can make the above contents of these functions into a big table and compare them for easy understanding and memory. Pay attention to the combination of function expressions and graphics when solving problems, and you will certainly get much better results.

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.
