I will not advice you to drop-out or in other words, throw a degree out of the window. I think @doosra does mention that you can just do minimal in college to get a degree and I think you should do that.
There are open courses from some of the best universities around and especially now that Stanford has Spring courses online, free; there is no way you should give up.
Spend more time learning and doing. You just don't only have online courses to see but also, the time is ripe to build things. We have an awesome platform and some good problems to solve. Maybe students like you will come up with some, who knows.
Happy hacking!
