So I'm not sure if Prof. Beer read up on previous culpa reviews, but my experience wasn't that bad. Everything was completely fair (tests/ quiz/ hmwk). The only thing that can be particularly difficult is the material. His tests were doable (there were mistakes every once in a while, but really not a big deal). And he is a very nice guy. He really wants people to learn the material. Like most science courses, his lectures can be quite dry. So, don't fear this class if you have to take it. Just do the work and you'll be fine.
