Retaking a Course for Grade Replacement

If you're looking to improve your cumulative GPA, schedule an advising appointment to discuss whether you'd benefit from retaking a course for grade replacement. If grade replacement is right for you, you’ll need to register for the class and then submit a grade replacement request form by the posted deadline for that semester or session.


After adding classes to your cart, you can continue enrolling right here. You can also drop classes and change your grade mode. If you prefer the old method of registration you can continue with classic registration instead.
