Not too easy. Not too difficult.
It's a great start to the subject if you start to follow it. Also if you like space even just the smallest bit it's really interesting to hear some of the material. Space is just such an amazing subject and even if you don't want to pursue this, learning a bit of it is super fun!
Learning about how light bends was really fun and interesting, it can move as a particle or as a wave and these things really affect how the planets are illuminated and how light is affected in our own Earth.

Advice for students:
You really need to stay awake for the course, but the topic and material was really interesting so if you choose this class odds are you can stay up easily. Studying before tests are a given but super beneficial. Material is pretty easy to grasp so just repetition is the part you want to focus on.
