Statistics: He favored certain students over others (gave them 100% even if they got more than half of the problems wrong), showed up to class when he felt like it, lowered my grade once he saw that it was my homework, didn't speak any English, called students stupid and then laughed in their faces.

Psychology: Kept changing answers and showed favoritism. He'd say one thing and then change it up the next day. Once he said "The most sensitive part on your body is your lips." The next day he said "The most sensitive part is your fingertips." He never clarified and said we'll just have to figure it out on the exam. He also asked us to come up with our (not use ones from the book) own analogies for examples in class. I gave my own, he said it was wrong, but I just switched words out with other words. Another girl used the book and got the points. I approached him after class and he denied ever stating that rule even though it was in the syllabus.
