I absolutely love Professor Kelley; he's the most engaging lecturer I've ever had. He is very radical and makes very very bold claims to grab attention, and then explains them. Very intriguing, very cool guy. The lectures for this class are an hour and fifteen minutes, and normally I get a little bored, but never during Prof Kelley's lectures. I plan on trying to take all his other classes even if they don't help me with any necessary credit. He doesn't just read off of slides, answers all questions warmly and in depth, and is overall just super cool.
This class is decently easy as long as you do the readings and attend lecture. After week 8 it's really easy because you're done with all the big assignments (besides the final). Weekly readings can be a little overwhelming but you can skim the long ones. Make sure to at least read a few because you have to use them for the final. My TA graded really easily and said all TAs have to go to norming sessions so I assume everyone was graded easily. I would recommend this class just for Prof Kelley!!
