According to this comment, if you can get the counselor to write a weighted gpa on the transcript, even if it’s handwritten, he would be eligible for the presidential elite scholarship: UA Presidential scholarship, am i screwed? - #10 by mom2collegekids
UGA is affordable with the classic scholarship and will also have plenty of graduate courses in both subjects.
OSU might also be affordable, and I would say they have the better academics over UGA.
Also, how would you plan to afford UMichigan in the unlikely case he was admitted?
