There is a big difference, that is, the problem of learning mode. The requirement of Math III is higher, and the concept investigation of Math IV is more difficult than Math III. Another point is that the number of calculus in the review of Math III and Math IV is relatively high.

The main points of distinguishing four papers

Different majors have different types of mathematics papers, so it is necessary to distinguish the key points of different papers and review them accordingly.

Liu Jiaoshou, Department of Mathematics, Tsinghua University, thinks that the biggest difference between the four examination papers for postgraduate entrance examination is that numbers one and two belong to science and engineering, and numbers three and four belong to economics.

Candidates who need to use mathematics more in frontier engineering or future research need to take the preliminary test, such as those who apply for computer, information, mechanics, aerospace and other majors. Candidates who apply for engineering majors and are not particularly demanding on mathematics in their future studies need to take two courses, such as urban construction and other majors. Candidates who apply for economics and business majors need to take three or four exams.

Some candidates majoring in economics believe that the number three or four in the mathematics postgraduate examination paper only tests economic mathematics. "In fact, otherwise. Count to three or four, or advanced mathematics. " Liu Jiaoshou, for example, said that in the mathematics test paper used by economics majors, one topic may involve some topics containing economic terms, such as how to minimize the cost of a product and how to maximize the profit of selling products. "But don't believe that counting three and counting four is to test economic mathematics. Take a set of economic series as an example. Mathematics 1, 2, 3 and 4 should be reviewed according to the requirements of science and engineering majors, so that you can get good grades. "

Professor Chen Wendeng said that the examination papers of science and engineering mathematics have the highest requirements for the examination of advanced mathematics, and the focus is on the analysis of solving problems in advanced mathematics. The examination paper of economics and mathematics requires higher linear algebra, probability and mathematical statistics, and candidates should focus on discrete two-dimensional random variables and their distribution.

Generally speaking, engineering majors take math one and science majors take math two, but some majors with low requirements for math are different because of their different research directions. Some take math one and some take math two, such as our GIS-Geographic Information System.
