i dont know if i would call texas a&m a "great" university.
but regardless, even when he was still a student, he was barely one apparently as he was still dedicating a lot of time to martial arts. I think for someone like him, it's probably a risk worth taking.
one thing not to forget is that college isnt for everyone. and a lot of people end up picking and easier major and graduate with a worthless degree. iirc, he was in an engineering program, but his course load was way less than what it normally is and i imagine its quite likely he wasnt getting a very good education in a real engineering major and wouldnt have been competitive with how slowly he would have graduated.
