Spring 2016 - Really, really, really strong accent that takes a long time to get used to. Not a standard Israeli accent, like, a strong one and he also yells in this high voice and sounds like a muppet. But actually not a super complex class, pay attention to slides (not super helpful to go to lecture) and you can get by.
Winter 2016 - Professor Levin sets his grades based off: midterm 38%, final 60%, and course evaluation 2%. He is very dry and relies fully on powerpoint. His test are focused mainly on what is presented during his lectures, but he does ask a few questions on the readings. In his test be sure to be thorough and give more than what he asks for, as I only answered what he asked and received a D. Honestly I should've studied more, but I cannot stress the importance of being extremely thorough on the tests. Good luck and remember to study for everything as his final is cumulative.
