Reviews of professor Hui Wan

Rating: 1.0/5, difficulty: 5.0/5
Lectures were so hard to follow that you end up zoning out most of the time. He barely speaks English. If you can avoid taking fluids with him, do it.

I feel the need to give Dr. Wan some justice here. He is not nearly as bad as initial reviews would suggest. Homework is leniently graded, tests less so. There is a communication barrier, but it's not hard to overcome ("barely speaks English"...please). Homework assignments were fair in their timing. All lecture content was provided in powerpoints.

Dr. Wan is not for everyone. He does have a heavy accent and there is definitely a lot of work that goes in to staying on top of the material.  HOWEVER, if you show up to class, read the textbook and remain engaged he is more than fair and is willing to work with you. If you show you care, he reciprocates and if you don't he won't either.
