(Whoops. I meant demi-gods, not students. But then again, gods and students don't teach other. Demigods train with other demigods, in order to train for battles or ask for advice; but they don't count on their parents unless they are giving up their food by the fireplace. The gods are just there lol. However, the gods that you posted were either exiled or punished, so they were sent to camp half blood to do whatever.
I hope this isn't confusing.)
