Frequently Asked Questions
How is Grade Point Average (GPA) calculated?
Each letter grade is assigned grade points (e.g. A = 4.0, B = 3.0). Multiply each grade point value by the course credit hours, sum them up, and divide by total credit hours attempted.
What is the difference between weighted and unweighted GPA?
Unweighted GPA caps all courses at 4.0 regardless of difficulty. Weighted GPA adds an extra 0.5 points for Honors courses and 1.0 point for Advanced Placement (AP) or International Baccalaureate (IB) courses.
How do plus/minus grades affect GPA?
Most universities count an A- as 3.7, a B+ as 3.3, and a B- as 2.7, allowing for finer differentiation than flat letter scales.
Do pass/fail or withdrawal grades affect GPA?
Usually, courses taken Pass/Fail or marks of "W" (Withdrawn) earn credits (if passed) but are excluded from the GPA denominator.
What is considered a good college GPA?
A GPA of 3.0 (a "B" average) is typically the benchmark for good academic standing, while 3.5 or higher is standard for Dean’s List honors and competitive graduate school admissions.
