For example, to scale the points awarded on the assessment spreadsheet (by default in \texttt{Z0}) with the number of tries (by default in \texttt{C0}), the adjusted score can be programmed in an empty cell in assessment spreadsheet row 0, where\\  \texttt{TEST\char`_EXPR?IF\char`_TRUE\char`_EXPR\char`:IF\char`_FALSE\char`_EXPR;}. The \texttt{if} statements can be nested. Suppose that students are to receive full credit for a correct answer on the first attempt, 3/4 credit for a correct answer on two attempts, and half credit for a correct answer on more than two attempts. To scale the points awarded on the assessment spreadsheet (by default in \texttt{Z0}) with the number of tries (by default in \texttt{C0}), the adjusted score can be programmed in an empty export cell in the Assessment Spreadsheet row 0, as illustrated by the following example:\\
