First, applications from different majors.
Math 3 is suitable for management and Math 4 is suitable for economics.
Second, the difficulty of the exam is different.
Mathematics four is more difficult than mathematics three. Math 4 needs more knowledge than Math 3.
Third, the scope of the examination content is different.
Math III and Math IV include high numbers, linear algebra and probability theory. But the content of Math III is bigger than that of Math III. In the part of mathematical statistics, mathematics is not tested in four, and mathematics is tested in three. Moreover, Math III is generally broader and more difficult than Math I in this part.
Fourth, the focus of the exam is different.
Math 4 has very high requirements for probability theory, even exceeding math 1.
Extended data:
Mathematics III, Mathematics IV The difference between Mathematics I, Mathematics II and Mathematics III after the merger;
First, the applicable majors are different:
Engineering majors with high requirements for mathematics choose computer technology and information engineering, engineering majors with low requirements choose mathematics Er Ru light industry technology and engineering, agricultural engineering and forestry engineering, and economics and management choose mathematics III.
Second, the examination scope is different:
The first range is calculus, line generation and probability.
The second area is calculus, line generation.
The range of the number three is calculus, line generation and probability (with emphasis on probability)
Third, the difficulty is different:
Math 1 is the most difficult, followed by Math 2 and Math 3 is the simplest.
