Currently, the gradebook view for your entire class does not indicate when you have inserted a grade for each student. I believe there should be a symbol (maybe a checkmark) that appears at the top of the grade book grid for each assignment to indicate to the teacher that you have finished grading that assignment. It would make sense for it to be up by the title of the assignment. Otherwise, you have to search up and down the entire grade book grid to see if you have any ungraded assignments.
