where do they learn this?

Over the past couple of semesters I've had a rash of students want to know if they can take the test then retake it if they don't do well?? In what universe is this acceptable? I've also had more than a few students tell me "I don't do well on tests" then look at me expecting something. My response is usually something along the lines of "figure out WHY you don't do well on tests and I'll do what I can to mitigate that but you have to take the tests". I have a feeling high school these days is a bit less... shall we say rigorous than it should be.
