[@Ninja] I have a few concerns. My main one is him being able to teleport to places he's been, it would be fine if he could teleport back to places of emotional importance to him, like the main classroom or his dorm. But being able to just teleport to a place that he's been once before could become very powerful. The second one is the range, maybe dial it down to 5km for starters. And expand on his personality a little bit.
