You can get a CS degree even though you're self-taught.
If you think you can learn more on your own than by listening to your professor, just go to class, sleep the entire lecture. Just be sure to pass the required exams, projects, etc., so you can get your diploma.
Another point of view:
Being able to go through 4 or 5 years of schooling just proves that you are serious (and patient) enough to go through the rigors of the jobs being offered to graduates of a particular degree.
Take note that some companies aren't convinced that self-taught individuals who did not go to 'proper' schooling can take the pressures of work.
Another case in point:
1. Linus Torvalds developed Linux while taking his Master's Degree at the University of Helsinki.
2. Bjarne Stroustrup (father of C++) is a postgraduate degree holder.
3. Brian Kernighan, Dennis Ritchie, Ken Thompson (and all other members of the original AT&T CSRG) are at least college graduates.
4. Bill Gates did not finish college during his DOS and BASIC days, but remember that he continued his studies after some time.
Doesn't that tell us something?
