6. Assigning Homework At The Last Second
We’ve all been there before: it’s Thursday or Friday and the lecture is winding down. From the looks of it, you’re about to escape without a weekend assignment. Just as you’re getting ready to start making those weekend plans, the professor hits you with that last second assignment.

7. Switching Up Due Dates
This one goes both ways. There are the professors who assign a great deal of work, watch their students bust their humps to get it all done, then decide to extend the deadline by a week the day before it’s due. Or they assign work and decide that it should be due earlier than you had planned. Both methods are maddening.
