@FtrEng42 given your son’s accomplishments, I think he will plenty of great choices. The top 4 you listed are so disparate in geography, vibe (actually about everything). Has he ever considered and articulated what he wants out the next 4 years, academically, socially, life experience? MIT is a great (maybe it and Caltech are the best) school for kids that already know they love STEM and want to be surrounded by other STEM focused students. You won’t get the big State U experience with the sports and wide range of activities (and students). If you haven’t done so, maybe a good exercise to go through would be to go through a list of college attributes and determine which are important to begin to better focus your son’s list.
