Berkeley used to let students skip the introductory CS course, 61a (in Scheme), if they had received a 5 on the AP CS exam. They removed that option I believe after fall 2010.

One of my friends was able to skip 61a by meeting with the department chair, Paul Hilfinger, and convincing him that 61a would be a waste of time for him. My friend could drone on and on about the simplest of subjects so we assumed he just annoyed Hilfinger until he said "enough already".
