Dr. Zimmer is the funniest and coolest professor I have ever had!!! I had her for Invertebrate biology, so it was a really fun class anyway (we got to play with lots of animals), and the material is really interesting. Dr. Zimmer made a point to learn everyone's name in the class, and the camping field trip was one of the most fun times I have ever had for a class. Since the material is just a lot of facts, Dr. Zimmer makes the lectures more fun with jokes and conversation. The tests are difficult but pretty straightforward. I would totally recommend taking her for an upper division class where you can really get to know her.
