Learn about each school's culture and consider which one might be the best fit for you. The following list is based on 2019-2020 admissions statistics (acceptance rates and standardized test scores) provided by the U.S. Department of Education. 01 of 08 Stanford University Andriy Prokopenko / Getty Images Located just 35 miles south of San Francisco in Palo Alto, California, Stanford University's lush, sprawling campus (nicknamed "The Farm") affords students plenty of green space and great weather. Stanford's 7,000 undergraduates enjoy small class sizes and a 5:1 student to faculty ratio. While the most popular major is computer science, Stanford students pursue a wide range of academic specializations, from art history to urban studies. Stanford also offers 14 joint degrees that combine computer science with the humanities.
