I hate to criticize the grammar nazi in you but in this case she's wrong. "Your" is used correctly. "Your" is the possessive form of "You" which is what is needed, not "You're" which is a contraction meaning "You are."
I understand that. These are the lines I was referring to.

Slide into the class your failing...
School is over and your not going home.
Now, the word "your" is used quite a bit properly, and, anyway, this is an easy mistake to make. In rereading I sometimes find myself puting "they're" instead of "their," but I've known the difference since the second grade. However, despite knowing this, using the wrong form often presents an air of apathy towards one's own work, because it essentially means that the writer did not edit and reread and perfect as extensively as he or she probably would on a piece that he or she cared about deeply.
