Update
He did not end up getting the full-ride at SeattleU and didn’t get into Brown. After doing some preliminary ranking on a set of criteria he came up with, he’s down to Tufts, American and Occidental (as expected). Next few weeks will be fun with Admitted Student events and more research. Would be happy to have him at any of those three options.
Thanks for all the input so far and feel free to add any other thoughts on the choice.
