The processor for the class just read off the powerpoint and if you ask questions he would just go back to the slide and read it again. He did not know any English except greetings. There is a lab connected to the class which counts for a large portion of the grade. For the lab I had (with Bin Xu) the professor would not explain how to use the equipment or the process for the experiment. She also did not know Ensligh and would start yelling at students when they did not understand her.

Do extensive research on the professors you will have before taking the class. I used to have migranes everyday after lab.
