Your son has been accepted to several fantastic schools. Honestly, his future depends on him and him alone. These schools are all more similar than they are different.
Why not let him take this very special moment in his life and let him make his first really big decision. The consequences of this decision being imperfect are inconsequential and educational benefits of actually making a big decision that impacts the future course of one’s life is empowering. Don’t rob him of that!
