AP Calculus BC is very accelerated and moves at such a fast pace. The class can get annoying, and no sugar coating that there are 1-2 pop quizzes every week, which means you must learn the content as soon as you are presented with it. THIS INCLUDES memorizing formulas such as arctan and arcsec. The homework problems are few and you are given a lot of time to do it (~40 problems over the entire unit) and they are intended to be done over the course of the unit. I would recommend doing these as you finish the course. For the unit tests, material from the course showed up a lot, but also feel free to look at the College Board practice he gives. There isn't much practice problems themselves but there are lots of opportunities to find practice problems within the internet so do that. No surprises on assessments, they cover everything from the course.
The teacher grades very fairly. The quizzes and tests are all based on material from the notes and there are no surprises, so you should study your notes thoroughly.
