I believe you can retake your classes to get a better GPA. Say you made a C in cem 101 and you retake it and get an A, i believe that if you get an A it will average out higher. This is somthing you want to be sure you sit down with a carrer councler about. There may even be some classes that you can take that count towards your carrer that you dont have to take that can buff up you GPA.
