On the contrary, it is actually very common for Ivy League schools to offer AP credit, or at the least allow you to use AP credit to fulfill a requirement / prerequisite. Princeton, Brown, Columbia, and the University of Pennsylvania all offer AP credit or allow fulfilling prerequisites. Outside of the Ivy League, Stanford offers AP credit. MIT offers AP credit for 2 classes and elective credit for humanities AP classes. None of these schools, however, will offer AP credit for all AP classes, since there is a lot of variability in the rigor of each AP class. Three of the AP classes that I've observed tend to be accepted for credit are BC Calculus, Physics C, and Economics. Physics C (for Mechanics and Electricity) was the most challenging AP test I ever took.
