The main difference is that the first and second universities are mainly suitable for engineering students and their non-engineering students. The content of art is more difficult, so the students who study college mathematics I are engineering or professional students, and college mathematics I is the first edition of higher mathematics.

Then Math II, that is, the second edition of advanced mathematics, is generally learned by students of economics and management, and the content inside is not too difficult, which is easy for students of economics and management to accept.

Then the number of works, that is, engineering mathematics, is the same as one of the best. Engineering mathematics is calculus, but engineering mathematics will be more inclined to prove, that is, to write proof questions, and then if it is one of the best, it will be more inclined to calculate.

The number of work will be more difficult than one of the best, which means that the difficulty of engineering mathematics will be higher than one of the best, and you will learn more. Moreover, engineering mathematics is studied more in mechanical or other electromechanical majors, which means that all students need to learn engineering mathematics.
