I Clepped basically an entire year of university. Higher education serves two purposes: Learning, and credentialing. And there's certainly faster ways to learn - so that leaves you with the credential. The cheaper and faster you can get it if you want that one, the faster you can get out into the world and do cool things.
At a good institution, you'll learn considerably more than you get examined on. The fact that you learned enough on your own to pass exams doesn't mean that you learned as much as a normal student.
