If you want an (A) you must watch all the videos, read and check the board daily, and most of all pay attention to what you are watching. When someone gets a (B), it pretty much means you are doing your work, playing by the rules but are most likely confused and are doing something wrong. A (C) is a grade us students can get from the lack of trying our best and from giving up. If you get a (D) or (F) you are showing no effort and may just be watching the videos while paying zero attention.
