Frequently Asked Questions
How is Cumulative GPA calculated?
Cumulative GPA = Total Quality Points (Grade Value × Course Credit Hours) divided by Total Credit Hours Attempted.
What is the difference between Weighted and Unweighted GPA?
Unweighted GPA caps grades at 4.0 regardless of course difficulty. Weighted GPA assigns extra quality points for advanced coursework (e.g., AP or Honors classes get up to 5.0 points for an A).
Is this based on a 4.0 scale?
Yes! Standard mode converts letter grades on a 4.0 scale with plus/minus increments. Weighted mode supports up to 5.0 for AP and Honors courses.
How does credit weighting affect GPA?
Grades in higher-credit courses (such as a 4-credit lab science) contribute more quality points to your total average than 1- or 2-credit electives.
