I am a math major and I did very well in my gen chem class. For bio and orgo, however, your math skills won't help much.

Btw, what's your major? I don't know about you, but you can't really tell whether you are really good at math unless you do really well in high level (400-500) classes. Calculus 1-3, DPQ, etc are joke compared to Abstract Algebra and Partial Differential Eqns. Of course, the same story with physics. Try quantum mechanics sometime if you haven't. Enjoy.
