What is the difference between deleting a student and unassigning a student?
When you unassign a student, you simply remove him or her from your class roster. The student is still available to all other users and you may assign him or her again if needed. When you delete a student, he or she is completely removed from the system and his/her information is inaccessible. Please dont delete a student unless you are absolutely sure you will not need his/her information again.
