Kevin is the best teacher I've had at UCLA. Not only because he teaches in a funny and clear manner, but also because of his kindness. He is very humorous, caring, and lovely. A number of us in the class had become friends with him. (he also has a lot of small dinosaur figures in his office that you can take for free c:) Buuuuut he talks rather slowly, so I sometimes watch the lecture recordings at 1.5x time speed.
The class itself is fun and easy if you are interested in basic geology stuff. I did really well on the midterm and the final with 2-3 hours of study the day before, otherwise, I don't read or study anything outside of class. Kevin has very clear slides with goals listed in the beginning, if you go through all of them you will be fine for the exams. It has two weekends of field trips in the Mojave desert with a long field project, so the workload is a bit heavy towards the end of the quarter, but it is a great experience for doing fieldwork, making friends, etc.
Labs are also interesting, the TAs are super nice, almost all labs can be done during lab time. The only heavy work we had was the field part. If you are having another class with a heavy workload, you might want to email Kevin and ask him for advice on to take it or not.
