The Doctor had to go to the Academy to become a Time Lord. Why he had such a low achievement record is anyones guess. Maybe he was a bit of a Shobogan in his youth... I know I was.
youth? according to your theory, he was helping Omega and Rassilon form the society of Time Lords. If that is true, I'd doubt you'd be able to refer to him as young by the time the academy got started.
