Undergraduate courses may be repeated. The transcript will contain a complete record of all courses taken and grades earned. Courses for which grades of Ds and Fs are recorded can be retaken without departmental approval; courses for which a grade of C, or pass, or higher are recorded will require departmental approval prior to registration. The transcript will contain a complete record of all courses taken and grades earned. The repeated and not the original grade will be included in determining the cumulative grade point average. However, after a student has repeated the same course three times, or has repeated three different courses, that student must have the permission of his/her academic dean before repeating any course.
