First of all the course material is not that hard. Yet the professor does a really bad job at organizing and explaining, he gives out brunch of papers every single class and most of them are missing the title and written by himself with an extremely poor writing. His english is not that easy to understand and he likes to make fun on student. I personally do not recommend to take his class cause I don't like his attitude and judgement on student. (If he thinks you are not one of those"good" students you are pretty much getting a bad grade).
