<p>^Not at all. Calc BC is probably the hardest AP. Those statistics are quite misleading - the only kids who take Calc BC are the best math students in the region, so it’s a given that most of them will perform well. In fact, Calc BC and Physics C are much harder than AP US History, which has approximately 10% of 5’s. APUSH has a more spread out distribution because so many kids take it, while only the math/science stars take Calc BC and Phys C.</p>
