Looks good Roxy, though university level english courses may fit better (not to say there couldn't be high school level, but the students would generally be older, though there is no telling how many dropped out of school so if that was your intent, it is fine)
No problem with college grade only.
I assumed it was more like the x-men thing, where it's a kind of shelter/recruitment program for those that have encountered the supernatural or are stuck with it, from which operatives or members of a larger, more structured organization are drawn.
Mwahahaha. I should invent a TA fer meself.
