Great professor, the biweekly worksheets were just extremely long. It took me about 15 hours to do each one. However, you definitely get a lot better at excel, and learn exponentially more compared to most intro courses.

If you are not an Astro major / this isn't a requirement, please don't take this class. I took this out of interest and regret it so much. The worksheets for each topic are unbearable, very long and tedious "groupwork" that you do by yourself and make up a significant chunk of your grade, easily the worst assignments I've had at UVA. This class uses a lot of trig as well, so if you are not comfortable with that, you will struggle to follow the concepts. Prof. is a nice guy and if the worksheets did not exist this class would not be so bad, but they do and it is. Have not had a test yet, only 2 moths in, but felt strongly enough at this point to come make this post.
Tldr: Great prof, awful class assignments, avoid taking
Note: this is the first time being taught so hopefully he fixes the worksheets for next time, otherwise avoid
