There are four courses in mathematics for postgraduate entrance examination. In addition to Math 1 and Math 2, there are Math 3 and Math 4. The standard of distinction depends on your direction. All of them are as follows: Mathematics 1: including line generation, high number and probability. The applicable discipline is: 1. Mechanics, 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, transportation engineering, ship and ocean engineering, aerospace science and technology. Two disciplines, the major is nuclear science and technology, biomedical engineering and other first-class disciplines. 2. Materials science and engineering, chemical engineering and technology, geological resources and geological engineering, mining engineering, oil and gas engineering, environmental science and engineering and other first-class disciplines have higher requirements for mathematics. 3. The first-level disciplines of management science and engineering management science are divided according to this, and most computer majors in colleges and universities will choose to take Math I..
