Mr. R,
Ofcourse they pay it all. At least from what ive understood from my bunch of friends that went to Oxford.
They pay no interest though(I believe GAA pays that).
The other guys would have rather went to Oxford and not Jordan had it been cheaper in Oxford, some of them DID have both options.
I COULD be wrong, this is just as far as I've been told.
Maybe the guys don't even know what they got themselves into.
