Hurry and read before I am flagged!
Some colleges are good, but get so popular that they reach “ivy” level admissions. Vanderbilt IMO is just more popular than it is good. I am not saying it is not a great education or in a cool city, but I am saying it is not top 10 - and that is where admissions difficulty has placed it. If you can get into Vanderbilt, you might as well go to Brown. Average accepted applicant is pretty similar.
