If you want to learn well, you have high requirements for mathematics. High number, probability theory, statistics, high generation and so on. Moreover, the higher the demand for mathematics in the future, the financial graduate students in many places are more inclined to recruit science mathematics majors. All kinds of models and derivatives have high requirements for mathematics, so the requirements for mathematics are also quite high. Of course, if you don't have high demands on yourself and don't want to take the postgraduate entrance examination or go abroad after undergraduate course, you can also learn math so-so.
