Auto Numbering Test Scores and want ties to count the same

[Scott]

I have a series of 300 test scores from students and want them automatically
numbered from 1-300 based on best to worst. The problem is I want identical
scores to number the same.
i.e. say after number 10 the next three have identical scores I want all
of those to number 11 and then the following score to be numbered 14.

=RANK(A1,$A$1:$A$300)

 

[Sheeloo]

Sort the scores in descending order (assuming they are in Col E)
Enter 1 agains the highest score (assuming you want the rank in Col F)
Enter =IF(E2=E1,F1,F1+1) in the cell below that and copy till end

Use the RANK function.
