Not too easy. Not too difficult.
I'd recommend this course because it is extremely educational but also fun at the same time. We always talked about other planets that may be sustainable to live on and watched videos on our satellites and where they currently are. On top of that we learned all about constellations and what they are.
I learned a lot about what it takes for planets to be considered livable. I also learned about the history of the universe and how we began to study it since day one.

Advice for students:
The best advice that I can give is to LISTEN to you professor. They usually understand that astronomy is a hard subject to grasp so if you listen to what he/she puts emphasis on, that's what's usually on the test/quiz.
