I took AP Micro online with flvs. The class is not too difficult when you try. I am an econ major, so the course came easy to me. I got a 4 on the exam, and the other person I took it with got a 5. The FLVS course is probably the best I’ve ever taken. VERY much prepares you for the AP Exam. I just caution you that Module 2-3 will be difficult (cost curves) but keep with it and you’ll be fine. I took the course in 3 weeks (I worked on it for hours daily, finished Mod 1 and 2 within the first two days).
