Grades are listed by code number. To find your code number take the last 5 digits of your SSN (e.g. 12359). Take the middle three digits as a number (e.g. 235) and add to the first and last digits (e.g. the 1 and 9 from 12359), giving in our example 235+1+9=435. This is your code number.See the current grades as a pdf file. You may also see what the curve looks like.
