Cornell course substitutions, study abroad courses, and courses taken at another institution may all be submitted for review via a substitution petition. All requests must be made in advance of course enrollment, with the exception of transfer credits taken prior to Cornell enrollment. When you submit your substitution petition, you must include a current version of the course syllabus. Only 1 substitution petition is allowed per minor for core courses. If you are considering to take a course outside of Cornell, you should check with your college’s registrar for specific policies about transfer credit before you begin the course.
