    Formula request: converting letter grades to numbers so they can be averaged.

    Can anyone suggest a formula that would take letter grades (A, B, C, D, and E) and produce an average letter grade?

    For example, a student gets a D on one assignment and a B on another. I want a formula that will produce "C".

    Thanks!

    Hi,


    =CHAR(ROUND(AVERAGE(CODE(A1:E1)),0))

    entered as an array formula will average the grades in cells A1 to E1.

    To enter an array formula, use CTRL, SHIFT & ENTER - excel will display it as

    {=CHAR(ROUND(AVERAGE(CODE(A1:E1)),0))}
    Rule 1: Never merge cells
    Rule 2: See rule 1

    With A-E in A1:A5, put this in B1 and drag down

    =CODE(A1) then in C1 put this

    =CHAR(AVERAGE(B1:B5))
