1. Brief Description

This use case allows a Professor to submit student grades for one or more classes completed in the previous semester.

The actor in this use case is the Professor.

The use case begins when the Professor selects the "submit grades" activity from the Main Form.

2.1    Basic Flow - Submit Grades

1. The system displays a list of course offerings the Professor taught in the previous semester.
2. The Professor selects a course offering.
3. The system retrieves a list of all students who were registered for the course offering. The system also retrieves the grade information for each student in the offering.
4. The system displays each student and any grade that was previously assigned for the offering.
5. For each student on the list, the Professor enters a grade: A, B, C, D, F, or I. The system records the student's grade for the course offering. If the Professor wishes to skip a particular student, the grade information can be left blank and filled in at a later time. The Professor may also change the grade for a student by entering a new grade.

2.2     Alternative Flows

2.2.1    No Courses Taught

If in the basic flow, the Professor did not teach any course offerings in the previous semester the system displays an error message and the use case ends.

2.2.2    Course Cancelled

If too many students withdrew from the course during the add/drop period and the course was cancelled after the beginning of the semester, the system displays an error message. If the Professor chooses to cancel the operation the use case terminates, otherwise is restarted at step 2 of the basic flow.
