This reminds me  one of my chemistry professor who didnt know how to teach. The worst professor that I ever saw. The professor used his solution book to solve numerical problems and could not explain the reasons behind the solution. Sometimes he even could not solve it and used to say, "I will do it tomorrow." But the exam questions looked like I was in MIT. we complained a lot and nthing happened. I heard he is still there teaching. The professor looked like homeless, rude. May b he had allergy with Neplease students..lol coz the class was filled with neplease students and around 10 american students and few chinese among 60 students.

Well, I dont think even if you complain to faculty head it gona work coz part of is ur fault too and you are responsible for ur own study. all you can do is talk with professor and if does not work then either fail or pass the exam. There is no solution behind your problem. It is the reason why you should do some research before taking that professor's class by asking previous students or doing online search in ratemyprofessors.com.
