Dr. Glass is an amazing professor. He posts all the powerpoints online, so a lot of people don't go to class...but they are very interesting powerpoints, and all the info you need for the test is on them. This class isn't THAT easy. Chances are you will still need to study for tests and there is a LOT of info, but it's basically just memorization

Fantastic professor. Engaging lectures. Had no interest in geology before taking this course, but looked forward to it every week. Highly recommend it, and not terribly hard. But study!!! I bombed the first midterm because I didn't think studying was necessary and then had to absolutely pull it out at the end.

Professor Glass is the best professor I've had at Duke so far. He's very engaging and he makes his lectures fun. I actually looked forward to going to class with him as the professor, and he makes lots of jokes and makes things easy to understand. His tests are very detail-oriented, so you should go to class and take good notes.
