rating scheme

Hi im doing a project in excel and i need to add a rating to it so that if its >50 its good if its >75 its excellent, i know how you would do this in matlab or c (just using an if loop) but no idea how to do this in excel.

any help would be greatly appreciated

P.S this is all on the same sheet so i dont need to interact between sheets

Using a formula like this will work.

=IF(B3<=49,"Average",IF(B3<74, "Good",IF(B3>=75,"Excellent")))

33 Average
25 Average
49 Average
51 Good
60 Good
75 Excellent

Where column A would be a name, B the score, & C the formula column.
