Professor wore an N95 mask and whispered the entire lecture so no one could hear her. We made her aware of this issue and she made minimal effort to try and get a microphone (she didn't get one). She also writes super small on her iPad so people couldn't see the board. She refused to post her recordings and notes so none of us knew what she talked about in lecture since we couldn't see what she was writing or hear her. The TA helped a lot.
