Understand and master the basic problems and solving methods of function, limit, continuity, differential calculus of unary function, indefinite integral and definite integral. Understand or understand the basic concepts, theories and solving methods of ordinary differential equations and differential calculus of multivariate functions. Understand the basic concepts and theories of double integral, vector algebra, spatial analytic geometry and infinite series.

If there is no foundation, we must study the knowledge system again, so that we can have rules to follow and evidence to follow when we do the questions in the future; For teaching materials, we must read them carefully and repeatedly. The blind spot when doing the problem is because the knowledge points are not carefully read.

So what is meticulous? After learning, there will be many marks in the textbook. These marks are not graffiti, but you organize knowledge points. There are many classic examples in the textbook. After you finish, you must quickly analyze the causes of the mistakes and form good habits.

What must be emphasized here is that when you review the system, you must refer to the outline of that year (if it didn't come out in that year, you can refer to last year's, and the content will generally not change much) to check for leaks and fill vacancies. Over the years, the real questions are based on the outline, and the examination outline generally has four requirements: mastery, understanding, understanding and re-understanding. The knowledge points that require "mastery through a comprehensive study" must be thoroughly understood, and the types of questions generally do not exceed this range.
