What school you go to doesn't depend on your origins. Cupid, Posea and Casta are arguably Gods more than they are monsters and myths are kind of like fairytales so I guess this gives them the flexibility to choose what school is best suited to them. For Cupid this is wherever she can be of help relationship wise. Posea and Casta don't currently go to monster high anyway, they just exist within it's universe. For other greek characters such as Gorgons, Minotaurs and Cyclops it makes sense for them to be at monster high as they are greek monster. While River Styxx goes to Haunted High as she works with the dead so it makes more sense for her to be where she is useful, like Cupid and Posea.
