I honestly really liked this class, granted thats mainly because it was easy. He goes over interesting material and is a pretty engaging speaker. It's all powerpoint slides though and there's no need to take notes so it is pretty easy to zone out or be looking at the clock as some of the derivations/explanations can be pretty boring. It's pretty cool you get to touch on general relativity and the big bang at the end of the class. His homeworks were all straight forward and pretty easy. Exams were straight off of his study guides and homework problems so as long as you studied those you were fine. I would recommend taking.
