To drop a student from a class while retaining information about the student in your gradebook, highlight the student’s name and right-click. Select Drop Student [student name] from the menu. A green Dr in the Grade column will indicate students who have been dropped from the class.
If you drop a student who is still in the class, the next time you open the gradebook, the Dr designation will be removed. Alternatively, if you add a student to your class and the student is not yet in the class, the next time you open your gradebook, the student will be marked with Dr.
