Weighted and unweighted high school GPA
Unweighted GPA uses the standard 4.0 scale. Weighted GPA adds extra points for honors, AP, IB, or advanced classes when your school policy allows it.
Colleges often recalculate GPA using their own rules, but seeing both versions helps students understand transcript strength and course rigor.
Why course rigor matters
A GPA is more meaningful when read beside the courses that produced it. Advanced courses can show readiness even when they are more difficult.
Use GradeAtlas to model regular and advanced courses separately before deciding whether a course load supports your admissions goals.

Frequently asked questions
What is a good high school GPA?
A 3.0 GPA is generally good, a 3.5 is strong, and a 3.8 or higher is competitive for many selective colleges, especially with rigorous coursework.
Can weighted GPA be above 4.0?
Yes. Weighted GPA can exceed 4.0 when a school adds extra grade points for advanced classes.
Do colleges use weighted GPA?
Some do, but many recalculate GPA using their own policies. They usually review both grades and course rigor.
