I have this major in my department, and one of my classmates has also studied it. The requirements for mathematics are higher than those for non-mathematics majors. Other majors are only advanced mathematics. You have to study the basic courses of advanced algebra, analytic geometry and mathematical analysis, among which advanced algebra and mathematical analysis are more important. There are also some compulsory courses about mathematics, such as operational research, calculus and so on. Moreover, there are specialized elective courses in mathematics, but the elective courses are relatively easy to handle, but mathematical software is not required. At the same time, you should also have some computer knowledge. You can learn more in this respect, and the school won't teach too much.

Personally, the previous learning foundation is not too important. There are many different learning methods in universities. Of course, logical ability is easier to understand and learn.
