This professional course involves interdisciplinary, which is difficult.
Main courses: elementary number theory, probability theory and mathematical statistics, mathematics teaching theory, primary school mathematics textbooks and methods, selected courses of mathematical analysis, complex variable function, modern algebra, selected courses of higher algebra, mathematical pedagogy, mathematics and applied mathematics.
Main practical teaching links: including computer practical operation and in-depth first-line teaching practice.
To sum up, I suggest you consider other majors. I am also a liberal arts student who graduated from university. A high number alone will overwhelm countless liberal arts students. If you choose a math major, the difficulty will increase geometrically.
