tons of professors berate students
I once had to keep asking a professor to get the online site for our book working for us (you have to register your class with the book company, and we paid extra for the online site in the book price, but he hadn't set it up) finally he set it up, and when he announced it to the class he said...
"One student wanted me to do this so I did, and I'll let you guys use it too, even though I think you all have enough resources already in the book and with what I give you, who knows why he wanted this useless stuff, but here it is"
He also made some other comments in there about how we'd be fools to overwhelm ourselves with so much information.
I even told him I just wanted it because they offered an E-book on the website and our book is several thousand pages long/thick....
Another time he started calling a student a liar and a thief when he misplaced an exam saying "In my 40 years of teaching I've never ONCE lost an exam so you must be LYING OR CHEATING!" while pointing in his face and yelling at him, but the guy was calm which I can't believe I would have been arguing with him.
Anyways in the next section they found his test, it got mixed up, I hope the student demanded an apology.
oh well, he's a decent teacher just sometimes gets on his high horse.
