But Gina Flakes, a junior from Augusta, Ga., can brag to her family and friends that she attends both universities.
Flakes, who is a junior international studies and political science major, wanted to study Korean for her foreign language requirement.
Because UNC-CH does not offer Korean language classes, Flakes' adviser told her about an agreement among certain N.C. universities that allows her to take the class at Duke.
Since the 1950s, UNC-CH has been involved in an inter-institutional agreement with Duke, N.C. State University, N.C. Central University, UNC-Charlotte and UNC-Greensboro.
The agreement allows full-time students of each university to take one course at another university involved in the agreement. But the course must fulfill a requirement for the student's degree program and must not be available at the student's primary university.
University Registrar David Lanier said more graduate students than undergraduate students take advantage of inter-institutional enrollment.
"The only reason you are supposed to go to another school is to take a course not offered here," he said. "The purpose is to expand your horizons as a student and make more varieties of courses available."
Lanier said one of the main obstacles of inter-institutional enrollment is commuting between the schools.
But Flakes said the time she spent traveling between UNC-CH and Duke was worth being able to have a car on campus.
