How GPA is weighted
Each letter grade maps to points (A = 4.0, A− = 3.7, B+ = 3.3 …). Multiply each course's points by its credit hours, add them up, and divide by total credits. A 4-credit A lifts your GPA more than a 1-credit A — that's the weighting.
Planning with it
Add hypothetical future courses to see what grades you'd need to reach a target GPA. Because credits weight the average, prioritizing high-credit courses moves the number fastest.
Frequently asked questions
Is an A+ worth more than an A?
On the standard 4.0 scale used here, both count as 4.0, though some institutions award 4.3 for A+.
How do credits affect GPA?
Grades are weighted by credit hours, so a grade in a 4-credit course affects your GPA four times as much as in a 1-credit course.
Does this handle weighted high-school GPAs (5.0 scale)?
No — it uses the standard college 4.0 scale. Honors/AP weighting varies by school district.
