You can drop each student's lowest assignment scores in an assignment category from GradeBook calculations. For example, you can drop each student's lowest two quiz scores.
Dropped assignments are not counted toward the points possible or points earned in GradeBook calculations.
Note The lowest assignment scores are not dropped if that would result in
dropping all scores in the assignment category.
For example, if you drop the lowest two quiz scores, those scores are dropped only if at least one quiz score would still be counted in the GradeBook.
After your GradeBook is updated, student category scores and grades exclude the dropped assignments from calculation of points possible and points earned.
