Pretty easy, overall.
I would highly, highly recommend this course if you enjoy learning about space. It's not too difficult, but it's definitely one of the most interesting and enjoyable classes that I've taken at USU.
The highlights of this course were the professor (Mike Taylor) and the lectures. I learned about the formation of planets, stars, black holes, etc., as well as the role of gravity in the universe, dark matter/energy, and more.

Advice for students:
If you have an interest in space then this course is good for you, but be prepared for a heavily lecture-based course--there are some demo days, but it's usually sitting and listening to the topics without hands-on activity.
