Professor Paul is very straightforward, and I thought his tests were very fair. He often used problems from hw and class examples on tests. If you show up to class, pay attention, and do your homework, there is no reason that you should not get an A. He is not there to mess with your head -- he really wants you to learn stats for practical applications. He throws some good one-liners into lectures too, so even if you think stats sucks (as did most of the people in my class, this being stats for social sciences) the lectures are alright.
