I noticed she's going to bottom out on C's from now on, thereby causing her to never have to make such a call again. Clearly abdicating responsibility and not doing her job. So, a kid turns in a test that he's just wrote "F*** You!" on, this is going to get a C? The same C that another kid got for doing fair-to-middling honest work?
This lady is not fit to teach, she should be fired. She should get a new job cleaning toilets.
