Entertaining lectures. Is great at explaining things but never over explains. Quizzes and exams are the only grades.

15B is definitely a much harder class than 15A so be prepared. There is no reading, but there is clicker. I was able to pull an A in 15A and a B in 15B. Just study hard and you'll do fine. There are a few papers and weekly quizzes, but they honestly help a lot when it comes to the midterm and final.
