But I want to remind you that there will be a big gap between your chosen major and your current imagination. As far as I know, 80% of college students don't like their chosen major. The reason is that there is a big gap between the original imagination and reality. So I suggest you don't have too many illusions. Personally, I think mathematics is a kind of thinking, not a simple technology or discipline, so there is no need to combine a lot of mathematics into university majors. In addition, mathematics itself and its application and combination in other disciplines are two different things. I suggest you don't care too much about your math. As the saying goes, the greater the expectation, the greater the disappointment. You can consult more experienced college students, but it makes sense.
