To tag onto what @ucbalumnus asked, did the size and happiness vibe at Tufts and Case resonate (something we can certainly relate to having visited both) or was it mix of majors?
If it’s the former, certainly look at WPI. They do have non-tech majors, but not in the same balance as Case and Tufts. The engineering program is innovative though, it’s in a good location, and everyone seemed happy.
We also liked Lehigh. The engineering program is strong and Bethlehem was far better than we expected it to be. It’s reasonably close to NYC and Philly if you need some city time.
Just a side note about Tufts…they do not offer any merit aid. Unless you have significant financial need, it’s going to cost you over a quarter of a million dollars to be a Jumbo.
