(from a manual for a grade management program):

Scores to Drop
This field indicates the number of lowest scores in the category to eliminate from each student's grade calculation. A Scores to Drop value can only be assigned to a category that has no sub categories. In addition, if there is more than one 0% score, the 0% score with the lowest amount of possible points/weight will be dropped. Furthermore, the Scores to Drop value is ignored when the value of Scores to Drop is greater than or equal to the number of scores actually recorded for a student in assignments with maximum point values greater than zero. For example, if the category is setup to drop the 5 lowest scores and a student only has 3 scores recorded, no scores will be dropped when computing the students grade.
