<p>Students at MIT are often more exclusively Math/ Science oriented but…all 3 are great schools with wonderful research opportunities. If you are looking for a more “well rounded” group of peers try Harvard Princeton. If you are pretty exclusively interested in Math Science, you will likely prefer MIT. MIT is very collaborative. I have to say my son’s peers at MIT turned out to be the greatest bunch ever – super smart but fun with no arrogance. Just all around wonderful people. By the way you can cross register betweeen Harvard and MIT.</p>
