I wasn't able to use version control at all when I graduated; I didn't even realize it was an option. I just every now and then would make a tar of my project in case I lost something.
I suppose I had copy/pasted some cvs commands from sourceforge in order to download the source of some open-source projects, but that was the full extent of my interactions with source control.
I know how to write some software before I went to school, but learning version control there was an eye-opening experience. It's the kind of thing I think they should teach in school to non-programmers. Anybody who writes anything, collaborative or not, is advantaged in some way by using it.
