Select if you want to run the utility for seniors only.
If you select to post for Senior (12th grade) students only, the utility will look through all course-sections marked Ready to Post in TeacherPortal and will only process students in grade level 12.
The utility will then reset the Ready to Post flag. This resets an instructor's course-section so that the instructor can mark grades as Ready to Post again, AFTER the course-section grades have been posted for grade level 12 students.
