Counting one is about half of counting two. Additional contents are probability theory, triple integral of high numbers, curve and surface integral, spatial analytic geometry, infinite series, and various small knowledge points, such as vector space generated by lines, Fourier series of high numbers, Euler equation and so on. Just reviewing knowledge points takes half as much time and energy as counting two. This means that when the students of Grade Two are strengthening the brush, the students of Grade One have not finished the first round of foundation.

The average score of Math One in Postgraduate Entrance Examination is always the lowest. Some people may say that the average score of number two is lower than that of number one in a certain year, which proves that number two is not difficult. But this logic is problematic. When using data for analysis and demonstration, we all know that we should discard unusually large or small data (abnormal values), which will affect representativeness. For example, when the judges score, the highest score and the lowest score will generally be removed, and then the average will be taken.

The difference between the first, second and third grades of mathematics for postgraduate entrance examination is that the applicable majors are different, the examination difficulty is different, and the examination content is different. Mathematics one is the most difficult, which is suitable for subjects with higher requirements for mathematics in engineering, followed by mathematics two, which is suitable for subjects with lower requirements for mathematics in engineering, and mathematics three is the least difficult, which is mainly suitable for economic management majors. Details are as follows:

1, you must use the subject of mathematics.

Mechanical engineering, mechanical engineering, optical engineering, instrument science and technology, metallurgical engineering, power engineering and engineering thermophysics, electrical engineering, electronic science and technology, information and communication engineering, control science and engineering, computer science and technology, civil engineering, water conservancy engineering, surveying and mapping science and technology, traffic engineering, ship and ocean engineering, aerospace science and technology, armament science and technology, nuclear science and technology, biomedical engineering, etc.

2. Be sure to use two subjects of mathematics.

Textile science and engineering, light industry technology and engineering, agricultural engineering, forestry engineering, food science and engineering and other first-class disciplines all belong to two disciplines and majors.

3, must choose a math or math two subjects (admissions unit).

Among the first-class engineering disciplines, such as materials science and engineering, chemical engineering and technology, geological resources and geological engineering, mining engineering, oil and gas engineering, environmental science and engineering, there are two disciplines. Whoever has higher requirements for mathematics should choose mathematics as the major and mathematics as the minor.

4. Be sure to use three subjects of mathematics.

First-class discipline of economics.

Management is a first-class discipline of business administration and agricultural and forestry economic management.

A first-class discipline of management science and engineering, awarded a degree in management.
