Pretty easy, overall.
I would recommend this course due to the overall knowledge it give you on our planet. Specifics ranging from sedimentary rocks to vague concepts such as plate tectonics can really give you a new outlook at what makes Earth so unique within the Solar system.
The best parts of this course was learning about natural disasters such as Earthquakes and Volcanic eruption. I learned how to distinguish different types of lava's and what they are composed of and how that affects their function.

Advice for students:
Re-read the lecture notes after class and every other day, so the information stays fresh in your mind.
