How do I delete "last year's" grades (which I imported from a text file or entered in manually) now that a new school year is beginning?

If you had a Grades page and entered grades info last year, you should delete that obsolete info by going to your Update Grades page and clicking "Delete All Grades" (or click "Reset Gradebook to Default" if that option is displayed on the Update Grades page instead).
