Just realized a way to power level alteration up to 100.
Find a mob in the wild that is near a rock or ledge. Hop up and agro the mob. Now just stand there and cast oakskin over and over. Since you are in combat you get gains continuously. Since you are in combat your magicka regens slow. But it works.
Illusion - spam courage spell any target, not considered an attack
Conjuration - summon something then hit it until it agros you gain exp, finish it off and summon again
Smith - iron daggers
Enchant - absorb health iron daggers
Restoration - stand in one of those traps with the moving blades back and forth just keep healing yourself
etc
They are all pretty easy to power level, pick pocket wait until you have two pieces of gear that give you +30% more chance or something
Speech would be the only thing I'd go out of my wait and get a trainer to level up
