The academic system of Dalian secondary vocational school is three years, so the math class starts from the first semester of the first year and generally lasts until the first semester of the second year. That is to say, math classes last for 3-4 semesters, and all specialized courses are offered in the third year.

Some majors have higher requirements for mathematics, and some contents of advanced mathematics, such as calculus, linear algebra, Fourier series, Laplace transform, etc. , will increase, so the math class will increase appropriately to match the professional courses.
