This class goes relatively surface level on a bunch of concepts, from Kinetics to Stars. It covers a lot, and some of it is kind of interesting. You can tell Prof. Liyanage is engaged and enjoys what he's doing, but how he taught just didn't stick for me. He wasn't the worst I've had, but he definitely wasn't great. If you need the credit, I did well enough, but I wouldn't necessarily recommend it. Its two lectures and one homework set a week, plus reading the textbook sections (though this is more or less optional if you need the supplement). Attendance is taken with in-class clicker questions which are graded though not hard and he talks you through a lot of them.
