Relating to my last post.... I have decided to give my student the A-.
I appreciate all of the comments. It was a bit unfair to ask for input based on essentially zero information.
In the end, I needed to consider whether she was an A student despite this technicality. The bulk of her work justifies the A-.
Grades are a tricky thing. For many of us teachers (but obviously not all), grades still mean something. They are a indication of the student's mastery of the material. This could become a very long post, but let me just say, an A in one of my courses means the student has the highest level of competence and mastery of material in that course. I only give As to students that deserve them. Many students don't like that policy.
