1, with different test contents:

Math II: It is an exam for students who apply for agronomy. The content of the exam is only high number and linear algebra, with more high numbers deleted and the least exam content.

Math 3: It is an exam for students who apply for economics. The contents of the examination are advanced mathematics, linear algebra and probability statistics. The high number part mainly focuses on the investigation of calculus, and there is no hypothesis test and confidence interval in probability statistics.

2. The scope and content of the test are inconsistent:

Math 2: including line generation and high number. The applicable disciplines are: textile science and engineering, light industry technology and engineering, agricultural engineering, forestry engineering, food science and engineering, all of which are two disciplines.

In the first-class disciplines of engineering, such as material 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 and majors that do not have high requirements for mathematics.

Mathematics 3: It is often called economic mathematics, including line generation, probability and high number. The applicable disciplines are: statistics and quantitative economics, and the majors in the first-level discipline of applied economics.

There are two disciplines and specialties in the first-level discipline of business administration: management, enterprise management, technical economy and management. Two disciplines, management, agriculture, forestry, economy and management, have higher requirements for mathematics.

3. For different students: Mathematics is aimed at majors such as agriculture, forestry, geology, mining and petroleum with low mathematical requirements; Mathematics three is aimed at management, economy and so on.
