I went into college able to write software in multiple languages across multiple platforms. I also skipped a bunch of prereqs and got the other mandatory courses out of the way quickly. But I learned a ton in my 4 years of CS classes, and would have kept learning a lot if I stayed for a couple extra years, I'm sure. I'll tell you that it was eye-opening to go from setting the curve in a mandatory class to struggling to keep up in a topics class. It depends on what your school offers, but if you can cherry-pick quality classes for the remaining two years, I'd say it's worth it unless a time-sensitive career opportunity comes along (e.g. founding a company). Or do a second degree with your free time if you're not that interested in CS.
