Hello everyone, I'm a high school student and wondering about the rigor of the AP Calculus classes that U.S. high school students often take. When I say rigor here, I'm talking about mathematical rigor as is commonly talked about with regard to math classes, and also whether or not the class is truly at college level. The impression that I have had so far from what I've heard about the classes and here on the forums is that the two classes (AP Calc AB and AP Calc BC) are near the level of a normal college level math class but are not mathematically rigorous. Could anyone with experience with these classes verify this, or correct me if I'm wrong? Another thing is, that the school I go to tends to have slightly modified AP courses. For example, the program that I'm enrolled in requires AP Environmental Science, which we are required to take without any of the prerequisites, so the class is modified to accommodate that. From what I have heard, our Calc classes are also different in that whereas some schools have the option to jump right into Calculus BC, ours requires AB first, followed by BC. They are also referred to as Calculus 1 and Calculus 2. Does this indicate that our classes are different and possibly more in depth? I would assume that being a STEM specialty program with highly accelerated math, my school wouldn't require you take a class you could get by without. Any and all help is appreciated, and thanks for any replies!
