It would be very helpful to allow schools to change what is seen on the progress screen for each courses' grade. We want to move to letter grades and not show a percent. Currently, it would show a percent on progress screen and letter grades for individual assignments.
I would add to this the ability to define different letter grading scales mapped to percentages by course.
We're a bilingual school, and in French track classes, a 75% means a high B where in the US system, it's a solid C.
