First Aid-Tsunade: Harry's past has been a rough one, and it's taught him the value of knowing basic first aid
Combat-Toph Bei-Fong: See above, except replace first aid with knowing how to kick ass. Harry's already been in quite a few fights with some unusual and unsavory characters, and he knows the value of being able to defend himself.
Criminal Law-Dick Grayson: Harry sort of has aspirations of maybe someday being a Private Detective. That, plus the fact that he's already been put on trial by an international organization means Mr. Grayson's class is rather relevant to his interests.
Firearms-Yoko: Harry has spent the past two years being taught and cared for by a ill tempered Scotsman in the South. He knows his way around a gun even if he isn't a crack shot, and knows that hokey religions and ancient weapons all the powers in the world aren't a substitute for a good blaster gun at your side.
Driver's Ed-Mia: Harry is an 18 year old boy who never got to finish driver's ed. He would like a car as soon as possible thank you.
