In fact, finance is also divided into liberal arts and science. If you are a liberal arts student admitted to university finance, then mathematics is basically not difficult. If you are a science student admitted to a university, then mathematics is basically an engineering requirement, which is more difficult. In fact, mathematics is not needed in the financial field. For example, to operate securities, you only need to be familiar with a few limited and useful formulas. Probability theory and calculus may be used more in finance.
Don't be afraid of finance. If the admission probability is high, finance is better. As long as you persist in solid study, it will help you out of a wonderful life!
