Not too easy. Not too difficult.
I'm indifferent about the class because the study guides the teacher makes are often vague and makes it difficult to discern what parts of the notes to study. However, lectures are often informative and are easy to listen to.
A highlight of the course is that you make a lot of friends through study groups (it's almost necessary to do well on a midterm) and group labs. I learned a lot about Earth's history and basic things that happened in each era.

Advice for students:
Make a study group fast and pay attention to what the teacher says during lecture. Often times slides only show pictures, so you need to write down what she says.
