And you thought the Ivy League was exclusive. A Stanford University student on campus.

Their acceptance rates range from 5.2% to 12.5%, and former Ivy League admissions directors say it's harder than ever to gain acceptance to the schools.

So you might be surprised to learn that other schools have even lower acceptance rates.

Business Insider listed schools that are even more selective than some of the Ivies, according to statistics provided on the class of 2021* admission rates from school websites.

*The rates for the University of Chicago and California Institute of Technology reflect class of 2020, as rates for the class of 2021 are not yet publicly provided.
