I took both AP Calculus, AP Computer Science A/CSP. CSA has you work with miniscule Java problems while CSP had you do things like define "big data" and what IETF stands for. Despite getting a 4/5 on the exams, I don't feel like they resembled anything like my introductory classes at a state university, and don't really seem to apply to either the academic wing of computer science nor software engineering. I'm sure part of that is likely due to teaching, as I preferred my highschool math teachers to the technology/computing teachers, but the curriculum seems misfocused at best.
