And the great thing about college is that if the prior statement is not true, then it's your fault. For the first time, you are responsible for your own education. If you only have easy classes, that's because you did not seek out the challenging ones.
I convinced the undergrad CS department to let me start taking CS classes first semester despite the fact that Exploring Engineering is a prerequisite.
Do you think you could help me get in to audit a few classes? I'm basically not allowed to take any more math/science classes this semester because I don't have the prerequisites. I was thinking about trying to get into MATH-3134 Applied Combinatorics.
Also, you might appreciate this web app/program that I wrote. http://hokienotify.me
It will notify you when a class you want has available seats. It syncs its database every 10 minutes or so with VT's.
If you want to learn more the best thing you can do is be a good student. If a topic interests you, stay after class and discuss it with a professor, or visit them at office hours. Opportunities abound for this sort of thing, usually in smaller classes though. I'd recommend getting used to college in your first year and then hitting up professors more when you have found your place at school.
If you're like me (it sounds like you may be), you're smart. Just wait until you figure out that there are other ways to gratify your intellect than coding. Take a class that has nothing to do with any sciences. One that you want to, not one that you're forced to. You just may enjoy it :)
Personal experience: I was very far ahead of what I needed to do in order to graduate very early on (credits that came in from HS combined with taking 17-18 credits a semester, every semester). As a result, I would either wind up graduating a year early, or I could take random classes in whatever I thought would be interesting (without falling behind!). I chose the latter. Due to that, I'm in what I think is a pretty unique situation; I can graduate in the next year with an undergrad degree in three completely unrelated fields, if I wanted to.
I'm actually taking a philosophy class that I'm really excited about. "Knowledge and Reality" which came highly recommended to me. Maybe I'll really like it and take a minor in philosophy. Currently I'm planning to dual major in EE and CS and maybe triple major with the addition of Math. Definitely not as varied as you, but we'll see. :)
