When running test analytics mine shows A, A-, B+, B, etc. This means the graphs are so small I cannot see the data and there are so many numbers it is difficult to keep track. While my grading scale needs to stay with all these, I would like my test analytics to show A, B, C, D, F. I thought I could set it that way before, but I cannot find a way to do it now. (My old numbers for comparison are only A, B, C, D, F.) How would I change that setting? Thanks!
