I don't understand why some cells are shaded and others are not, and I don't know how to turn off the cell shading (assuming it's possible to do so.)
Thank you very much in advance.
The passing grade must be set for each grade item.
In our situation we require an 80% or better for passing, so I actually have a script the runs on a schedule and sets the passing grade to 80%. This way the course builder doesn't have to worry about setting it.
