Under the old system of FAWeb there was a simple option to View Students With Historic Information. Students have switched sections due to class schedule changes, but from the onCampus teacher's point of view, it appears that all the information that was recorded (posts and grades earned) in the previous section is gone. If there is a simple way to view this, please let me know.
Otherwise, WHY remove something that was so valuable and useful to a teacher's gradebook?
The teacher of the new section would run the Grades for Dropped Classes report from their gradebook, then they can transcribe them into their gradebook.
