All I have to say is if you are going to college or university, check out
www.ratemyprofessor.com. If this guy is "grade by how I feel or how well I like you" guy, get on and make sure he gets a negative rating. College is not cheap, and I think that ratemyprofessor is a good way to get into the classes you need and get the decent professor.
One caveat: use your common sense on reading the ratings...I have seen quite a few on there that it was obvious the student just hated the teacher and rated him low in every category because of it...
