I have a teacher that established a due day for a quiz on February 7th at 11:59 PM. He made the assignment available until February 8 at 11:59 PM. I confirmed this.
He had all assignments graded and up to date by February 10th in the evening (last night)
He is saying that when he got online this morning he had additional submissions to grade for students. You can see their time spent is literally thousands of minutes. In Speed Grader it does show it was submitted on February 8 at 11:59, but why would it not show up until this morning under Grades?
Any light you can shed on this would be appreciated.
