This professor is rude and arrogant. He and his TA are unhelpful and unaccommodating. This prof skips steps in his examples, his assignment solutions are often full of errors. He examples and assignments barely gloss over the concepts you need to know to write his tests. Due to COVID there were 11 weekly quizzes with 4 questions where the response was a numerical answer and no points for work shown? Most of the class waxed wildly from 0-100 on these tests.

Try to take this class in the fall with a different prof. The assessment may be the same but you may have a fighting chance with someone who can actually teach.
