In terms of difficulty:
Judging from the syllabus of the past years, it may feel that there are few knowledge points in the exam of the Third Institute of Mathematics, and it will be easier to prepare for the exam. In fact, it is not, because it has few knowledge points, but it is very refined, which means that it requires not the breadth of knowledge, but the depth! And don't forget that Math III is mainly aimed at candidates majoring in economic management, so the difficulty of the exam is not much simpler than Math I. ..
As far as the examination content is concerned:
The number three is consistent with the number one in the distribution of topic types, 1-4, 9- 12, 15- 19 belong to the topic of higher mathematics, 5-6, 13, 20-2 1.
Advanced mathematics, linear algebra, probability theory and mathematical statistics, these three parts should be read, and they should not only be understood, but also applied and extrapolated. After all, that's where the difficulty of Mathematics III lies. It is mentioned in the question that "the university only studied for one semester and skipped half a semester", so let's guess that semester is a high number.
Please pay attention to the proportion of these three parts in the book, which also plays a vital role in choosing whether to prepare Mathematics III: linear algebra, probability theory and mathematical statistics account for 22% of the total score respectively, and high numbers account for the largest proportion, accounting for 56%.
At the present level, it takes a lot of time to prepare for Math III. If the liberal arts have a strong understanding ability, they can only use their spare time for review at ordinary times. It is recommended to consider preparing for a master's degree first, so the success rate of preparing for a master's degree is higher. The admission fee will be lower.
