\label{Spreadsheet_OOO_Rows}
Once a sheet is saved, there is a one-to-one relationship between a
certain row and a specific student in the course-level sheet, and a
specific assessment in the student level sheet. Thus, specific cell
names like ``A5'' can be used in calculations. Changing class
enrollment or course content, respectively, after saving a sheet will
bring the row numbers ``out of order''.
