Shu Gao II is a major that requires a lot of mathematics but does not require professional level, such as psychology. Shu 1 Shu 2 theoretically uses the same book (the same school), but the teaching content of Shu 2 has been deleted, so it is not required to master all the contents, but only the basic contents.
Math 3 seems unheard of.
Mathematics 4 is aimed at liberal arts majors and requires a certain mathematical foundation, commonly known as "liberal arts mathematics". The textbooks used are different from the numbers of 1 and 2, such as economics and literature.
