Be realistic.

Advanced mathematics is not easy to learn, so master the basic mathematics in the course first. If the school environment permits, if possible, go to other classrooms to listen to math classes, ask math majors more, or skip social training classes.

I hope all your wishes can come true.

Join a graduate class and listen to a math class in the freshman classroom. Mathematics is not difficult. If you work hard, you will be admitted. Good luck.

It's hard, but as long as you work hard, you should have no regrets. Let's fight it out.
