Over 50 students dropped out of 125 by the second midterm. His lectures typically did not cover material that was relative to help with homeworks or exams. The average on the first midterm was around 45/100 or something like that, absolutely ridiculous considering this math is fairly concrete despite it's inherent difficulty. If you are good at self-teaching then you have a chance. Thanks to this class/professor I am seriously considering changing majors.
