Professor Okin is an excellent professor and conveys information effectively. His exams were difficult but very straightforward, meaning that he doesn't try to trick you, but he makes sure you know the material. Make sure to record his lectures because his exams are straight from what he talks about during class.

My only concern/annoyance of the class was that non-geography majors get screwed. There were a lot of graduate geography students and undergraduate geography and environmental science majors who had an upper hand, smothering the curve. So beware, if you're an EEB major be ready to study your butt off!

Nonetheless Okin is a very good teacher and a fairly easy tester.

Professor Okin is a great professor. Took his GeoM127 class about soils and he turned a pretty bland subject into a somewhat interesting subject. Best advice to you is to record the lectures or find a friend who does. The textbook is basically worthless. He gives you a set of study questions for the midterm and final. I aced both the midterm and final by just re-listening to his lectures and answering the study questions as they came up. Was not difficult at all if you pay attention in class and understand the concepts which aren't that hard.
