May I take UN1105 Principles of Economics pass/D/fail?

Yes, you can take Principles pass/D/fail, even if you decide to become an economics major or concentrator. You must receive a grade of P in order to satisfy the Principles requirement. If you receive a D or an F then you must retake Principles of Economics. Please note, however, that you cannot take any other economics classes or your math and statistics courses pass/D/fail and have it count toward the major or concentration.
