Pryal is a relatively new professor, but I thought overall he did a pretty good job. Lectures contain all the necessary information for the quizzes, so you can get away without reading the textbook but it is helpful to clarify confusions. You definitely will need to put in the time to study for the quizzes - they aren't designed to trip you up but you do really have to understand the content. It is very easy to get 100% for in-class participation, and the labs aren't too difficult. The homework is graded on accuracy and often takes a lot longer than the website (MasteringAstronomy) predicts. Personally, the content wasn't always the most interesting (as a non-science major) but there were definitely some lectures that were better than others, and Pryal is very clearly interested in what he is teaching. If you're searching for a relatively easy class to fulfill a science gen-ed, I would say this is a good option. The workload is definitely reasonable for a 1000-level course, and I think Pryal is a good professor to take this class with.
