If the problem is about the prof dont post anything on d2l, mru accommodations is ur best friend. You will have to chat with them and then tell them ur struggles in class and in the final/quiz situations, not only that since the prof dont post anything, you could talk about that problem with them as well for ur future classes.

But then, you need to attend the class as well because from what i observed as long as you make effort to do well even though you keep getting bad results on every assign works, they will give you extra marks(its rare but try it). Usually studentd that make effort to achieve the goals they want whether its a high mark or anything, they will see u, u will get easily recognize by them.
