Not too easy. Not too difficult.
I would recommend this course because it's a nice beginning of astronomy, and definitely gives some food for thought. There are so many things we know and don't know about the Universe! It's an interesting course even for people who may not be very inclined to study science-related things. However, science is very much a large part of our lives!
Learning about black holes and spacetime was by far the most interesting and mind-blowing thing I've ever learned. Spacetime is fairly simple to understand and grasp but the idea of it is different than time as we know it. Black holes are so mysterious, as we will most likely never know what actually goes on inside them unless we went in ourselves- and if we did, there is no way of communicating to others about it or coming out.

Advice for students:
For sure keep up on the quizzes. They are mandatory and part of your grade, but it was also a nice review I did at the end of the day, after I've had time for the lecture to soak in a little bit. While it's interesting, it's a lot to take in and absorb!
