    Working out an average for the best 8

    Morning,

    Any help would be greatly appreciated. I have attached the spread sheet to give some clairty.

    In column O I have the total number of points a student has
    In column P I have the average number of points a student got for each lesson

    What I am trying to put in column Q is a formula that will work out the average score of the HIGHEST 8 subjects, rather than them all.

    Thanks

    Try this array formula

    =AVERAGE(LARGE(B2:N2,ROW($1:$8)))

    commit with Ctrl-Shift-Enter, not just Enter

    To avoid error if there is less than 8 numbers use:

    =AVERAGE(LARGE($B2:$N2,ROW($A$1:INDEX($A$1:$A$100,MIN(8,COUNT($B2:$N2))))))

    (ctrl+shift+enter)
