"How much is Notre Dame tuition, room, board, food?
How much is a ND degree worth over the graduate's lifetime?"
But, if he chooses to NOT exercise that option, what does he need to pay back? When he signs his scholarship, he has accrued 4 years worth of college education (along with room and board) -- after 3 years, he has cashed on on 3 of them -- so, he has used so far what he has accrued -- and still has not utilized his 4th (likewise, the university has only expensed 3 years of this as well) -- since he is not using the 4th -- who owes who what? The university may have committed to 4 years, but they have not expensed 4 years yet.
And, who is to say that he will not finish his degree (I think Jerome Bettis -- and many other guys), ultimately get their degrees -- the degree is only worth the field you are using it for (or to begin your professional life).
Conversely, does a kid who gets a 4 year academic scholarship and decides to "quit" school after 3 to pursue his dream job need to "repay" the 4th year of his academic scholarship back?
