When giving tests, the assignment is only open for a short window of time. If someone is absent on the day of the test and needs to make it up later. No problem, I turn on the test for that individual and he/she takes it. However, all the other student's grades are dimmed out for the assignment. If I go to speedgrader, i only see that one student. How do I fix it to see ALL my students grades. I've looked everywhere!
