How do I drop the lowest grade in a set?
Put all of the items in the set into a grade category. For example, if there are 5 in-class quizzes, create a category "quizzes" (using Manage > Categories) and assign the 5 grade center columns to that category. If you've already created the columns, you can add them to the category using "Edit Column Information" on the menu in the column header.
