Your major department will check your major course and the registrar's office will check the USG core. If you need to substitute any courses for required major courses, your department head will assist you. If you need to substitute a core course, you will be required to fill out a course substitution petition, which must be approved by the faculty. No course substitution can be considered approved until you receive a written notification from the registrar's office. Course substitution petitions are available in the Office of Student Records, or in some cases, in your major department.
Instructions are on the form.
