I had the same experience in college. I was more into web technologies, and everything we did in school was in Java. I did tons of projects for fun, most of which nobody ever saw but myself. Pickup a web language like ruby/python/php and start making anything. I was kind of bitter for a few years after college because I felt like all the skills I had had that I actually took to the workplace were self taught. But now that I am a bit further along in my career, and working on larger systems with more advanced problems all the theory, data-structure logic, and thinking of things like big O are coming out and I'm much more appreciative of the theory that I learned.
