If you have questions about assignments, the course, etc...ask them in class or during my office hours. Don't wait until the end of the semester and then complain in my evaluations that you never understood what I wanted.
Please don't think that just because you were admitted to an "ivy-league" institution that you don't have to work anymore. You aren't getting an A from me for just showing up to my class; you are expected to work.
Guess what, the people that read those evaluations know exactly what they are a reflection of. So please do not think that you are going to significantly impact my career with your melodramatic and groundless critiques.
p. s. Have a nice summer.
