Believe it or not! After you read those bad comments about him, you should truly evaluate your choice to take his class. It will hurt your GPA. I chose not to trust those comments and worked very hard (went to all his lecture and took very detailed notes) but still could not figure out why I could not get an A?! He is very old school and you pretty much have to predict what he wants. His lecture has much information but is very monotone and boring. I have no doubt about his knowledge but he's not a good professor. At the end of the course, ppl asked him what class he will teach so they can avoid him. That's how bad it was.
