Standard 4.0 plus/minus scale: A+/A=4.0, A−=3.7, B+=3.3, B=3.0, B−=2.7, C+=2.3, C=2.0, C−=1.7, D+=1.3, D=1.0, D−=0.7, F=0.0 — weighted by credit hours.
Enter your previous GPA and prior credit hours. The tool combines them with this term’s points: (prevGPA × prevCredits + semester points) ÷ (prevCredits + semester credits), adjusted for retakes.
When cumulative mode is on, mark a course as a retake and choose the old grade. The calculator uses grade replacement: the old attempt’s points are removed and the credits are not double-counted. Policies vary by university.
