@ucbalumnus As another poster pointed out, their child took just cal, not AP cal, and yet tested out of cal at their destination school. A certain portion of class time is spent prepping for the exam, plus the AP exam is given in early May. A school system may not end until late May or even mid June. The 2 classes may ultimately cover the exact same content as AB, but the non-AP class may utilize those extra weeks to cover the equivalent material, but simply not spend time prepping for the AP exam or conform to the AP schedule.
That was the essence of my point. In order to be AP, a course needs to prep for the AP exam. Being a non-AP course does not mean it is necessarily inferior. Not saying that it isn’t, just that it isn’t necessarily the case.
