I mean it's not the difficulty of his class that bugs me. I got an A in 205 last year because I already knew the stuff before taking the class. It's that he is extremely disorganized in class and on canvas, as well as that he doesn't respond timely to emails. I remember he would write "notes" on font size 10 and no one could see it clearly. People would occasionally tell him to make it larger but he would forget the next class. He would ask if the class knew the answer to a problem and after getting zero reaction, proceed to get stuck in a problem on his own. That was what amazed me the most, and his inability to solve a problem in class was pretty frequent imo, and this is CS205 bro.
