From the CHE fora, dr_mk’s post:
I’ve taken to putting all their grades on the course management system and letting it calculate their “final” grade.
Then I download the grades into Excel and do the actual final grade calculation, where I drop some grades and weight things according to what I laid out in the syllabus.
Since the overall final grades that I calculate are usually higher than the grade that the CMS spits out, I don’t get a lot of “how close was I to the next higher grade” types of questions, because they think I’ve already bumped them up a grade.
