Classes

I have a fascination with certain aspects of graphic design such as colors, spacing, typography, etc., and the more I try to teach myself this information, the more I want to take classes in specifically these areas. The problem is, my school is so small that they offer bits and pieces of these knowledge in classes that just don't interest me. I want to go in depth about typography, for example, and I don't know where to learn about it. I know the art teacher knows it, for he gives students a typography project that takes one week or less of the overall art program. That frustrates me so much! I know I could learn more if I took the class, but I would have to only learn a little, then move on? ARGH. I need someone to teach me :(
