First, master concepts and theorems. There are many concepts in mathematics that reflect the essence of things. Only by figuring out how it is defined and what its essence is can we really understand a concept. All the questions can only be done well on the basis of understanding. Theorem is a correct proposition, which is divided into two parts: condition and conclusion. For the theorem, candidates should not only master its conditions and conclusions, but also understand its scope of application, so as to be targeted.

Second, do the exercises in the textbook. What reminds learners in particular is that the examples in the textbook are very typical, which helps to understand concepts and master theorems, pay attention to the characteristics and solutions of different examples, and do appropriate exercises on the basis of understanding examples. Be good at summing up the problems-not only the methods, but also the mistakes. You will gain something after doing this, so you can draw inferences from others.

Third, clarify the context of knowledge. To learn advanced mathematics well, we must have an overall grasp of what we have learned and sum up the knowledge system in time, which will not only deepen our understanding of knowledge, but also contribute to further study. Advanced mathematics includes calculus and solid analytic geometry, series and ordinary differential equations. Especially the content of calculus is the most systematic and widely used in other courses.
