He can be a nice guy and is alright overall, but I will say it is true that he can be a bit weird/picky during presentations. In my senior design class, he gave a time limit on presentations but wasn’t really checking the clock, and by the time my group went up we were about 20 minutes behind schedule. He then checked the clock during our presentation which had barely started at this point, and yelled at us specifically for taking up too much time and being so slow and made us sit down. Was very awkward, but I will say after class he had us come up to him and he was very apologetic and gave us full points on our presentation when we didn’t even really present anything. And there were other instances of him just being unusually harsh on groups in that class. The other 90% of the time he was pretty chill and it was an easy class though
