A hard ass class that will require you to stress over the smallest insignificant shit like not reading the last page of the chapter.

Also, includes some stuck up pieces of shits that act like they know everything and give you the dirtiest look for not remembering when a boat crossed the ocean. Fucking fucktrumpets.
"Dude, are you taking WHAP?"
