1) take the math major, which is relatively easy to take. If it is pure mathematics, there seems to be no other way out except to be a teacher.

2) Take the computer direction exam. If your major is computer science, you can consider it. Computer direction is also better for employment.

3) Take the financial direction, which is also the choice of many people in the Department of Mathematics. You can consider it. It's also a good job.

4) Choose another major that interests you.

However, it is difficult to prepare for interdisciplinary meetings, so don't ignore mathematics. Don't think that you have no problem with math in the math department. When my classmates took the postgraduate entrance examination, many of them fell into mathematics, and the mathematics of postgraduate entrance examination attached importance to application, which was proved by our mathematics department when we studied. The emphasis is different. . .

Finally, I wish you success!
