@CupCakeMuffins If he goes to the campus I suspect he does, I know a number of very accomplished STEM-oriented students who will be attending next year due to the very generous merit scholarships offered to high stats students. Hopefully he will find them! Has he done the usual things - looked for clubs or ECs where he might find more like-minded people?
If it’s really such a poor fit, he might look into transferring, although as you know, scholarships are tougher to come by for transfer students. Hope things look up for him.
