Pouria was an awesome professor. I was incredibly impressed by his ability to teach one of the hardest classes in the major with little notice. He was extraordinarily accessible and very helpful outside of class. Go to office hours. He's definitely NOT an "easy" grader, but that's typical of major classes and not at all unexpected from dynamics.
I like the way he is teaching. The questions on the test came from lectures and hw. This is a hard course, you should study hard for this class!
