To allow courses with grades below your minimum

The following table gives instructions for RU exceptions, which can be created either in EARS or from the
370 screen of the SDB.  However, if you want DARS to accept a course with a grade below the minimum
for a given requirement, use an RR exception, available only from the 370 screen.

To allow special topics and ancient courses to apply to Areas of Knowledge
Use the CS exception.
