In Fall 2015, the P/D/F policy was amended to include the following language:
At the point of declaring a concentration, students may appeal to rescind a P grade received for a single course taken in a previous semester in order to meet a prerequisite or departmental requirement for entry. The transcript will then reflect the letter grade earned in that course. Students wishing to make such an appeal should consult with their residential college director of studies. Students entering a certificate program may also appeal to rescind a grade of P earned in a single prerequisite or required course for that certificate provided that the program requires a letter grade for entry.
Please consult with your Director of Studies if you wish to rescind your P/D/F grade and you believe the above conditions have been met.
