The difficulty of financial mathematics is ok, but you must have a certain foundation, otherwise it will be difficult. If you don't do academic research, it's basically applied mathematics, but you must thoroughly understand the basic theories involved (because the direction of mathematics is different from that of majors), otherwise you can't carry out your work. The mathematics required by certified public accountants is simpler than the finance major, and the future work is only a small part of finance, and more is enterprise financial management.
