A slight correction... The Advanced Placement(AP) CS programs use of C++ is a fairly new addition to the program, and with plans to start using Java in place, a short-lived one. When I took test back in 1995 they were using Pascal and judging by the condition and age of the texts, Pascal had been in use for about ten years prior.

My personal experience w/ APCS was interesting. On the first day of class, we had ~20 students. By the end of the first week the number had dropped to 10. When time came to take the test only 3 remained. The three of us breezed through the test having 15-20min left over at the end. Unfortunately, due to College Board rules, the proctor was unable to let us leave early so we were forced to covertly fling skittles at each other.
