Easy exp as Sora
The easiest way that I know of to gain exp is to use the sleight tornado multiple times and try to pick up all of the enemies that you can, but if you are in a battle that has no fire type enemies use the move Mega Flare. I think you learn that at level 57 but if you have to work your way up to it it's totaly worth it because you will wipe out all enemies by using it one to two times.
