\label{Spreadsheet_Student_Visible}
To change the spreadsheet sheet that students see, use \textbf{Save
As...}  on the level of spreadsheet that you want to change, and check
the box \textbf{Make Default}. 

If you only want to change the sheet for specific assessments, save
the assessment level sheet and do not make it default. Instead, on the
student level sheet, use the pulldown menu next to the particular
assessment.
