Answer:
You can make use of nested IF statement to solve this problem.
Explanation:
The equation should look like this:
=IF(Score>=90,”A”,IF(Score>=80,”B”,IF(Score>=70,”C”,IF(Score>=60,”D”,IF(Score>=59,”F”,"INCORRECT GRADE")))))
On the cell wherein you wanted to output the result of the grade, you can write this formula:
=IF(A1>=90,”A”,IF(A1>=80,”B”,IF(A1>=70,”C”,IF(A1>=60,”D”,IF(A1>=59,”F”,"INCORRECT GRADE")))))
*A1 is the cell where the user will input the grade, then B1 is where you will type the formula to get the result of the letter grade.
