When an assignment is curved, the original student scores are replaced by curved scores. If you’d like to keep the original scores but not have them impact student grades then try this: 1) Choose Assignment from the Chart menu. 2) Press on the assignment’s row number to select it. 2) Choose Copy from the Edit menu. 3) Choose Paste from the edit menu while the column is still selected. It will become duplicated. 4) In the status column, change the status of the original assignment to Not for Grade. Optional: change the Progress Report option to Exclude Assignment. Be sure to curve the duplicated assignment instead of the original.
