Ok, I'm the type of student who pays attention and does pretty well, but I absolutely could not stand this professor. The first couple lectures were fine, but then he started lecturing in circles. He would put the same equation on the board day after day, then give you another that's supposed to be derived from the original equation, but fail to explain it. And when he did explain it, it was in a circle.
He also never made eye-contact and mumbles just when he's getting to his point.
His tests were supposed to be pretty fair. Most of the problems were, but the issue is that they were vague as all hell. You didn't know he wanted for the question, and if you have a horrible TA, you get it wrong, even though it's right.
In a nutshell, avoid him if you can, OR just teach yourself out of the book.
