4. Too Much Homework
Earth to prof: your course is not the only one on the docket. A student needs to be able to divide their time equally throughout their entire course load, a fact that is lost on certain professors. The fact that students have other course work to complete and would like to maintain a semblance of social life isn’t important to them. It’s okay, though, who needs sleep after all?

5. Tough Grading
Ever had a professor who graded so tough that it seemed impossible to get an A? For some of these professors, it’s almost as if they enjoy being too tough on their students. Whether it’s deducting points for answers that are correct but not correct enough or subtracting an entire letter grade for not using the proper writing implement, these educators make college much more difficult than it needs to be.
