I was only in college for a brief stint, but I ran into this problem as well when I went to college. Although I hadn't been in the industry yet, I was a hobbyist for a long enough time for the intro to CS at my college to be simply pointless. After a couple weeks, I was able to convince my professor that I should be able to test out, and despite the fact that there was no procedure, I was able to just take the final exam, pass, and move up to the next course.

That next course also seemed pretty basic, but I hit a brick wall, because I didn't have the required math credits to get into the next course up if I tested out of that one. And testing out of a math class, while certainly doable, was not as enticing as a prospect :)

The truth is, while it's reasonable for an intro to CS course to be kind of basic, I think it was a good sign that either college, or at least the college I was going to for computer science, was not a good option at that point in my life. Thankfully, circumstance would knock me into the industry instead in short order.

(Now I'm interested in college, but not for computer science.)
