Quater Grades

I knew almost instantly when quarter grades were delivered to parents. I checked my school email at 4:30 today and I had four emails from parents and students about their quarter grades. Mostly why is my A student getting an incomplete? There are a couple of different answers to this. It depends on the student. In some cases the student is not actually an A student. In other cases it was because they have on skill that they failed. So all they need to do is one simple retake. In some cases it is because they have not returned their first test to me, so I do not have all of their grades. (There was some confusion. I thought all of the grades were written down when I handed the tests back, but not all of them were. And not all of the students have returned the test to me.)
