Third, according to the nature and characteristics of each course, we should grasp the "line", "point" and "face" of each course for scientific and systematic self-study. To overcome the disorder and confusion in self-study, we should start with the characteristics of each course, grasp the "line", master the "point" and understand the "face" to study systematically. The so-called "line" is to grasp the clues of the evolution and development of each course content. The clues to the evolution and development of the content of economic management courses include the following situations: 1, clues according to the passage of time. We know that the theories, methods and systems of economic management develop with the development of society. In this way, we can divide the vast course content into several stages or parts to learn and master according to the clues of time. For example, in the study of political economy and national economic management, the understanding of its contents can be divided by time clues, so as to deepen the understanding of traditional, current and target systems, theories and methods, compare and observe them respectively, and facilitate the grasp of the overall content. 2, according to the logical relationship clues. Such clues account for the vast majority of economic management courses. It is no exaggeration to say that almost all economic management courses are arranged according to this clue. For example, western microeconomics studies the standard perfectly competitive market first, then studies the imperfect competition, and gradually corrects the previous assumptions and enters the real market research; Another example is western macroeconomics, which first studies the operation of closed economy, then gradually introduces it to the government and foreign economic departments, and then studies the macro-control policies of open economy. These are all logically the same. Friends can see for themselves what clues you have learned in this book. In this way, from the whole to the part, from the part to the whole, we can have an overall understanding of the course content and a specific understanding of the content of each part. 3. Observe the angle transformation on the question and study the clues of the inheritance and development of the method on the question. Such clues are not uncommon in economic management courses. For example, the explanation of a theoretical problem often has many points, but after careful analysis, it is found that it often expounds the same proposition from different angles; The arrangement of some chapters also has this feature. Another example is the inheritance and development of various research methods: the input-output method was invented to solve the problem of multi-sector management; In order to solve the optimization problem, linear programming method can be introduced on the basis of input-output method. In industrial economic management, industrial correlation model can be used to describe industrial correlation; Hoffman coefficient and structural similarity coefficient can be used to solve the problem of industrial structure similarity and correlation. Various structural change value formulas can be used to explain structural changes. The so-called mastery of "points" is the mastery of key points, difficulties and doubts. There are numerous theories and methods in the discipline of economic management. In self-study, mastering key methods can often achieve a time-saving and labor-saving learning method. For example, the mathematical methods used in various economic management courses are nothing more than elementary algebra (addition, subtraction, multiplication and division model), linear algebra and linear programming, correlation regression, factor analysis and so on. Therefore, taking more time to learn these key methods is beneficial to the study of all courses. Each course has its own core content and core chapters, and it is very likely that the topics in general propositions are in these key chapters, and the core chapters account for a large proportion in a test paper. When you encounter difficulties in self-study, there are several ways to deal with them: first, asking teachers or classmates will get twice the result with half the effort; Second, thinking by yourself is helpful to cultivate independent thinking ability; Third, I really can't think of it. I can skip to the back, and sometimes I suddenly understand after a while. It should be noted that when encountering difficulties, you can make some marks in the notebook, which will deepen your impression. I think we should follow this principle in dealing with doubts in self-study. Mastering the "three-point" learning method mentioned above is the only way for most successful people. The so-called understanding of "noodles" means understanding the general knowledge of economic management, which is of great significance for broadening our thinking and deeply understanding the contents of textbooks. The acquisition of general economic management knowledge can be achieved by reading, reading newspapers, reading magazines, watching TV, watching movies, socializing, talking and listening to the radio, or by consciously paying attention to the economic activities of units and family members. In short, we should use various forms to increase our perceptual knowledge of economics and expand our knowledge, which is of great benefit to improving our economic cultivation and theoretical abstraction ability. The reason for this is that you don't have to be a pure "nerd" to learn economic management. Its theoretical background is rooted in the real economic system and economic life, and it has strong practicality. It is better to know this truth early than late. Those who know early will realize early and benefit early. Finally, send a famous saying, not a famous saying, as our words to encourage our friends who take the self-study exam: "Students who take the self-study exam should have confidence in life and themselves. Self-learners feel their needs from the needs of society. Self-learners must first be confident. "
