I am 4 classes into the program and enjoying it a lot. The surprising thing for me is that a single class seems to consume about 15 hours per week. I have heard that the harder classes, such as AI, IHPC, ML, GA, take 20-25 hours/week. I don't remember my undergrad courses being so demanding but I did not attend a top tier school.
All that said, perhaps for the sharper students these classes demand much less time than they do for me.
