This window allows you to link a major with a set of courses that you want to include in the major GPA calculation (example). Advising also uses GPAs by major (or degree plan). If you use Advising, you probably will not need to use the Major/Minor table.
Many users of Registration have the need to calculate grade point averages for selected student courses. The Work Quality Points & GPA option calculates GPA for the student courses that you choose. One common GPA calculation is based on courses within a student's major. The major table provides a way to select a student's Major courses for the GPA calculation.
During implementation of Registration, you must decide which course components the Major table will use. You may change the Major table at any time. However, the table must be complete before you run the option to calculate GPA for selected courses.
