I hate letter grading with a passion.

I have no less than 7 students in the same class who final grades are between 79 and 81% And depending on how I adjust (because it's a presentation class where grades can't be 100% objective depending on how hard I try) all of these students can have either a A or a B. I even have two students, who are good friends with a 79.4 and a 79.5 which means one should have a B and the other one a A.

This is all so very stupid. Why can't grades be plain numbers?
