The amount of free time you have in college is ridiculous, and the gathering of minds is a real thing, if you have smart faculty, and you have smart students, use them (a lot of startup stories seem to start with "I got together with a friend of mine from college"). Also, a lot of the stuff in computer science that doesn't change over the years is what a good curriculum will teach.
As in, learn spanning tree algorithms, computer architecture (and why things are built how they are), graph theory, whereas you might be learning topics like "how dependency injection works in AngularJS" outside of school (which isn't BAD, but it's not timeless, graph theory is pretty timeless).
