At least four semesters of full-time study must be completed in Philadelphia while enrolled at the University of Pennsylvania. The value of the Penn experience lies not only in courses taken but also in participation in the life of the University community both in and outside the classroom. Students must also be registered for their last two semesters at the University, including registration through its approved programs for study elsewhere. No student may graduate with a B.A. from the University of Pennsylvania unless he or she has completed at Penn at least one-half of the total number of required course units. He or she must also complete at Penn at least one-half of the courses required for his or her major.
