    PHYS5 . Berenstein D A Month Ago

    I took him for 25. His accent is hard to understand and his writing on the boards are illegible so I just started taking my own notes. He doesn't answer a lot of questions. The homework and quizzes are easy though. He seems passionate but almost removed from society. I would take him again because his class seems fairly easy on your own.

    PHYS5 . Berenstein D 15 Years Ago

    Dork/Nerd but funny. Material is pretty hard and confusing but the tests were fair. Definitely easier than crap mastering physics. Appears very busy man, so flaky on midterm solutions posting. Lecture slides are online! but most lectures are incomprehensible. I hate to say it, but reading Freedman's book helped. Just don't read too much into detail
