Open Easy Grade Pro software. Locate the "Chart" menu and choose "Assignment."
Choose the "Can be Dropped" option for assignments that you wish to have the option of being dropped. For example, if you choose every assignment for this option, then every assignment has the option of being dropped from the student's record.
Choose the "Score" option from the "Chart" menu. This will re-score each child's grade, with the lowest score being dropped. This score will have a small "d" located beside it to indicate that it has been dropped.
