I dropped out of my CS school to pursue a career of my own choice i.e. business of software. I've been quite successful so far. However, you've no idea how how much I want to go back to school but irony is that it's no more an easy choice. It's really hard to go back to school later in your life. I dropped out of school because I was kind of bored too. I will reckon that you should stay at school. Attend as many math classes you can. Also, take the hardest courses you can find in your school. Remember, these four years is the most important time in your life and this is when you can really enjoy life. TRUST me. Keep attending the school. In the interim try different things. IF something takes off and has a potential to grow only then consider this choice. Now that I'm married and badly want to go to school but you've no idea how hard it is. I know eventually I will.
