That's one of the reasons I never did well in college. I wanted to take Math, Physics, Theather, and thats it. I don't need a lit class for a mathematics degree. I am an excellent writer, and I have a better comprehension of the English language, both written and spoken, than most people around me. I would get bored, not do the work, only concentrate on my math classes, and I wound up getting screwed in the end because of it.
My advice? Concentrate on the positive, the classes you do like, and just bite the bullet. Not great advice, but its all I have.
