Work Step by Step
During both semesters, Nicole receives two A's, two B's, and one C. However, during the second semester, Nicole receives the C in a 1 credit class, but during the first semester, she receives a C in a 4 credit class. Thus, even though the grades are the same, since GPA is weighted based on the number of credits of the class, Nicole has a better GPA during the second semester.
