Fall 2018 - Ben is one of the best professors I've had at UCLA and the best professor to learn quantum mechanics from on this campus (The man is effectively a quantum mechanic (?) himself and he understands the material to the bone). This class is HARD. You start with a linear algebra review and then hit the difficult abstractions of the subject right away. The first problem set is pretty easy, the rest get extremely hard and will take a lot of effort to figure out. His grading is 50% homework so the class is meant for you to figure out stuff via problem sets, a teaching philosophy that I quite like. It's strongly recommended you have a good math background to succeed in the class because quantum mechanics is a physics class after all. He does not hold back here. Work together and work with Ben. This class is very rewarding if you take the time with it.
