Well, there is nothing wrong about it. I had to take three upper division math classes from a person who I still consider to be the worst professor I ever had (several math majors agreed with me.) I never showed up to class for the second and third quarters, except to take the exams, although I did turn in all the homework, I demanded from students to write my essay lectures, but never provided practical classes. My lectures were more than worthless.Thank you for reading this. Now you can write any feedback you want.
