We just started our second quarter and we set up our grade books for four quarters. Our teachers already set their grade calculation to “School year” and now want to change assignment types and percentages moving forward. Can this be done without impacting grades from the last quarter? Should/Can they change their calculation to “Marking period” moving forward? Can they remove or add assignment types? My assumption is that last quarter has already past so changes now would only impact assignments/grades moving forward. But I'm not sure. Any help is appreciated. Thanks.
