' Formula in cell F1 (copied down):
' =SumColumns($A1:$E1)

Dim c
Dim lngLoopCtr As Long
Dim lngTotal As Long
lngTotal = 0
lngLoopCtr = 1
For Each c In r.Cells
Select Case lngLoopCtr
'value of the letter grades are A = 4, B = 3, C = 2, D = 1, F = 0
Case 1, 3, 4, 5
Select Case c
Case "A"
lngTotal = lngTotal + 4
lngLoopCtr = lngLoopCtr + 1
Case "B"
lngTotal = lngTotal + 3
lngLoopCtr = lngLoopCtr + 1
Case "C"
lngTotal = lngTotal + 2
lngLoopCtr = lngLoopCtr + 1
Case "D"
lngTotal = lngTotal + 1
lngLoopCtr = lngLoopCtr + 1
Case "F"
lngTotal = lngTotal + 0
lngLoopCtr = lngLoopCtr + 1
End Select
'column 2 had different values for the letter grades such as (A = 12, B = 9, C = 6, D = 3, F = 0)
Case 2
Select Case c
Case "A"
lngTotal = lngTotal + 12
lngLoopCtr = lngLoopCtr + 1
Case "B"
lngTotal = lngTotal + 9
lngLoopCtr = lngLoopCtr + 1
Case "C"
lngTotal = lngTotal + 6
lngLoopCtr = lngLoopCtr + 1
Case "D"
lngTotal = lngTotal + 3
lngLoopCtr = lngLoopCtr + 1
Case "F"
lngTotal = lngTotal + 0
lngLoopCtr = lngLoopCtr + 1
End Select
End Select
Next c
SumColumns = lngTotal
End Function

With your data beginning in row 1, cell A1, enter the following formula in cell F1 (then copy it down):

=SumColumns($A1:$E1)

Have a great day,
