If you really want to choose 1, of course, financial management is good, although I know it is difficult to find a job after learning financial management. Even if you do, your salary will be very low in the first few years.

However, if you choose financial mathematics, the salary will be harder to find. So financial management is better. Financial mathematics, if you don't graduate, basically graduation is really equal to unemployment (unless you are the second generation or the second generation, it will be much easier).

Of course, you plan to take the postgraduate exam. I still suggest that you study financial management first, and then take the master's degree in finance.

But to say the least, it is very broad, and your tone may be good. If you like, you can enter normal university, study mathematics education and come out as a teacher. Your income is high and stable, so you don't have to worry about work and unemployment.
