Known for its Fighting Illini fans and massive parties like Unofficial, this is UI's first time landing at the top of the Princeton Review's list. The ranking is based on a survey that asks students about "the use of alcohol and drugs at their school, the number of hours they study each day outside of class time and the popularity of fraternities/sororities at their school."
The two most recent schools to top the list - Syracuse University and the University of Iowa - both made the top five this year.
