Yan had a hard time structuring his lectures, and only covered particular portions of the class. But combined with the TA and his office hours, help could easily be found. Additionally, his curve was very fair and it is very possible to get a good grade in his class. The homework was graded on correctness, which was a little difficult since he only covered certain concepts in Lecture. Overall, the class was a little hard to maneuver but in the end is very fairly graded.
