I can think of two methods. Which you use depends on the complexity of your
need.
If you only have two choices, a simple If/Then/Else statement will work.
In cell B2 type =IF(A2="G-Bachelor's Level Degree","AA+","No Degree")
You can nest the IF statement for up to seven choices.
If you have more than seven choices, then create a table of those choices
with the Education Level in Column A and the Degree in Column B. Name the
table "Education". Then, in your file that needs the degree, type a VLOOKUP
formula in B2 that looks for the text in A2 in Column A of your new table,
and returns the degree in Column B.
=VLOOKUP(A2,Education,2,false)
