I was already writing various types of software, taken a class in high school, gone to summer camps, etc, before I reached freshman year of college. There was plenty of students who had never even touched a programming language before and it was all brand new to them.

And I still learned things my first year (especially in ancillary classes, I only took three computer classes my freshman year), I just didn't get much out of CS classes until sophomore year. One of those classes was a gimme class I really should have tested out of ahead of time in hindsight, though (basically computers 101, I had quizzes on identifying what was the desktop, mouse and monitor).
