DE Calculus at my school is regular calculus, not business calculus. DE Calculus at my school covers the same material of AP Calc AB, but at a slightly slower pace. However, I would get college credit no matter what whereas with AP Calc AB I would only get credit if I do well on the exam. In addition, the teacher for DE is better than the one for AP, students consistently perform a lot better in DE. Furthermore, while I am good at math, it is not one of my best subjects and I do not have the motivation to study it much. A fun DE Calculus course with a great teacher that I know I will excel in seems like a better idea than a stressful AP Calculus class with a very stressful teacher. I understand your point though and I appreciate your responses.
