So I think I've come as far as I can with design by teaching myself. I really need to polish my graphics up and even look at better understanding fundamentals of design, as I have no formal training. So for someone like me without a formal education in design, what would you guys suggest in terms of online classes, books, and good tutorial sites for becoming better at PS, Illustrator, and overall a better designer (including typography, layout etc). Basically the closest to earning a degree without going back to college.

Thanks guys!
