In Blackboard Ultra Course View, instructors can apply calculation rules within the Gradebook’s overall grade column to customize how category totals are calculated. Specifically, they have the option to drop one or more of the lowest (or highest) scores within a category, provided the number of graded items exceeds the number being dropped. This feature supports greater flexibility in grade calculations, helping to accommodate outlier removal or support student performance improvement, but it requires at least two non-exempt items per category to function correctly.
