Remember terms more than anything, focus during the economic lessons when in APUSH, otherwise the lectures arent super important just a vague overview. Teacher rambles so listening vaguely is ok occasionally. Definitely, whatever you do, read the chapter. Her class is VERY textbook base and often she makes you learn the material on your own before she goes over it. The workload is extremely high if in other AP classes, but if you manage your time well you will be alright. Good luck!
