"Well, I'm trying to learn stuff about transfiguration illusions because - medallions, so probably a lot of, 'Lets turn this thing into this other thing a lot and try to make sure the spell doesn't break' but there's some stuff involving control of water, air, finding people - so on. I don't know what a sphinx is good at, so you may or may not turn to be fantastic at one of them and barely need any tutoring in it at all. If that happens I will ask you for lessons."
