What colleges are in tier 1, tier 2, and tier 3?

Frothyshake- Sorry old list I guess. Best I had. Vanderbilt I suspect easy top 15. Amazing school and very very selective! Please fill in the actual number if you have it.

Just opinion/guess is peer to Duke to Dartmouth range?

I was talking methodology more than actually defining. Do you disagree with the approach in principal?
