You might want to try and send a letter of appeal to the admissions board at whatever university he got denied from. Seeing as he was awarded a full scholarship to said university, I would say he has a pretty strong case for them to reconsider his admissions decision. Being from California, I know a couple of people who submitted letters of appeal to a couple of the UC schools and I know at least one of them had their rejection reversed to admission. Bottom line is it can't hurt.
