Pretty easy, overall.
I recommend this course as a Gen-ed. While slightly dense in material, it was relatively easy to learn and the course itself was really interesting. There isn't any readings and only 1-2 very small assignments due each week.
This course was very informative. It discusses a lot about earths history and the history of life that it not taught in grade school. There is some cool information about Dinosaurs and their history. You get to learn about acient animals I would have never known existed, for example Giant Ground Sloths the size of bears,

Advice for students:
Attend lecture but there are lecture notes online that are very helpful and discuss what was learned in lecture if you miss it. Study the overall concepts, the minute details are less important.
