There’s an abundant stream of college rankings based on anything from “smartest” students to “sexxxiest” students to the mythical students who are “both hot and smart.”

But if you thought these never-ending lists are enough to consult for an ideal dinner date — you might want to check out one more ranking before making that reservation. Paid matchmaking service The Dating Ring collected 7,500 date feedback reports from 1,600 people over an 18-month period to see which college alumni served as the most enjoyable dates. Datability scores were calculated based on the percent of people who said that they would opt for a second date and ranged from 17% (for Babson College) to 81% (for Colgate University).

The Best:

Colgate University Lehigh University University of Texas Austin University of Southern California McGill University University of Delaware San Francisco State University Boston University Northwestern University Williams College

The Worst:

Babson College University of Chicago Rutgers University University of Washington Michigan State University SUNY, Binghamton (Binghamton University) University of California, Berkeley University of Pennsylvania Princeton University University of California, Santa Barbara

Of course, there are caveats. While 316 different colleges were represented, the results weren’t representative of the whole country. A whopping 81% of those surveyed between March 2013 and September 2014 live in New York City while the other 19% live in San Francisco.
