You'd be surprised how far rote memorization and Google along with a little cheating can get you.
I have a friend currently finishing up his third year for his CS degree. I've tried helping him for the entire time, but he really just doesn't give a damn enough to actually learn. He somehow passes all of the tests, but I know for a fact he could not pass FizzBuzz right now. I know. I've given it to him and watched him completely fail to even decompose the problem let alone start working on a solution.
