The following rule appears in State University’s current catalog:
A course in which a grade of C or better has been earned may not be repeated. The second entry will not be counted in earned hours or grade point index for graduation.
Rod took his business math course and earned a C. Not satisfied with his grade but unaware of the catalog regulation, Rod took the math course again and this time earned a D. The registrar entered the D grade in Rod’s cumulative average. Rod objected based on the catalog rule, but the registrar said that the rule applies only if a higher grade is earned. What should Rod do? Should the grade count?
