How do I assign a letter value to a range of data?

[clatters69]

I want to create a column of percentage scores which will be test results for
students. I teh want to convert the percentage scores into grades. For
example, if a pupil scores between 80% and 90% this can be corresponds to
garde A. How can this be done?

With column of scores in A enter this in B1 and double-click to copy down.

=LOOKUP(A1,{0,50,60,70,80},{"E","D","C","B","A"})

Adjust for score ranges or more letter grades like C+, B- etc.

=LOOKUP(A1,{0,31,41,51,61,71,81,91,101},{"E","D","C-","C","C+","B","B+","A"})
