Category scales These scales are used to calculate the Total Scale in the main worksheet. Each number indicates the lower cutoff for the corresponding grade. The upper cutoff for a grade is equal to the lower cutoff for the grade above it. Student sub-total scores You cannot change these scores. They are displayed for reference only. You can toggle between displaying scores and grades by using the “Show scores/Show grades” item on the Sub-totals menu. The Category Sub-totals This window displays the category sub-total scores for each student. The upper left corner tells you how many students are in the class and how many categories you have created.
