If a student successfully repeats a course after initially earning a D or F, the better grade will be replaced in his or her grade point average. In other words, the first grade earned will be listed on the transcript with 0 credits next to the course. The second grade will be listed with full credits and counted in the grade point average. Grades are replaced for a maximum of 15 units during the student’s years at the Ziegler School. Beyond 15 credits, both grades will be recorded and counted in the overall grade point average.
