Word to the wise: do not this class or any class taught by Luss.
It was a complete waste of time that I enrolled in because another class did not meet my schedule requirements.
He mumbles all through lecture, attendance is required. He would sometimes ask questions, at which point the 15 students wake up. We all know the answer since he doesn't actually teach us anything new, but we have no idea what he has just asked so we always have to ask him to repeat himself.
I could go on, but save yourself from the worst professor I have had at Columbia.
