Read the book carefully first. After reading each chapter, do exercises after class. There must be many problems that can't be done at this time. It doesn't matter. Mark what you can't do with a pen, and then do the following questions.

Look through these books and find out where it appears. Think about it. If you really can't think of anything, just take a look. You can always find similar examples.

After doing the complete book in the above way, start to do the simulation test paper. If you can't, look at the textbook catalogue and find out which chapter and section it is related to. Then read the relevant chapters carefully and come back to do the problem.

There are several formulas to recite, such as basic function formula, L'H?pital's law, mean value theorem, derivative formula, integral formula and differential formula. Examples should be done well. In fact, the examples are all based on formulas. Just do it well. Those formulas must be tested in the exam.

Homework is very important, so you must do it carefully, with good quality and quantity, which can be compared with reference books. It's easy to forget the content of the last class, and maybe the next class, so it's necessary to review.

After learning a chapter, it is best to do all the exercises that have not been done in this chapter, which is convenient for organizing and is also a test of your own learning situation. Otherwise, when you wait for the exam, you will find that you still have a lot of questions you don't understand, which will be in trouble. The form and difficulty of the exam are similar to the exercises after class. It is very useful to do these questions before the exam.
