Weighted vs. Unweighted GPA: What AP and Honors Courses Change
October 21, 2026
An unweighted GPA treats every class the same on a 4.0 scale, so an A is always a 4.0. A weighted GPA gives extra points for harder courses, commonly +0.5 for honors and +1.0 for AP or IB, so an A in AP can count as 5.0. Take five classes: an AP A, an honors B, a regular A, a regular B, and a regular A. The unweighted GPA is 3.6, and the weighted GPA is 3.9.

Unweighted points: A = 4, B = 3, A = 4, B = 3, A = 4, adding to 18. Divided by 5 courses (assuming equal credits), that is 3.6.
Weighted points: AP A = 5.0, honors B = 3.5, regular A = 4.0, regular B = 3.0, regular A = 4.0, adding to 19.5. Divided by 5, that is 3.9. The weights reward the harder schedule.
| Course | Grade | Unweighted | Weighted |
|---|---|---|---|
| AP course | A | 4.0 | 5.0 |
| Honors course | B | 3.0 | 3.5 |
| Regular course | A | 4.0 | 4.0 |
| Regular course | B | 3.0 | 3.0 |
| Regular course | A | 4.0 | 4.0 |
Credit Hours Matter Too
If courses carry different credits, GPA is a weighted average by credit, not a simple average. A 4-credit class with an A counts twice as much as a 2-credit class with an A. Multiply each grade point value by its credit hours, add the products (quality points), and divide by total credits.
Weighting schemes vary widely between schools, with some adding nothing, others adding up to 1.0, and a few using scales as high as 6.0. Always check your school's own policy.
How Colleges Look at It
Many colleges recalculate GPAs on their own standard scale, often unweighted, or consider your weighted GPA only in context with the rigor of your courses. Some publish middle-50% GPA ranges on a 4.0 scale, which is designed to compare applicants fairly across schools.
Taking a harder course and earning a B can still look better than an easy A. It also depends on your goals and workload, so choose courses where you can do well and learn.
Frequently Asked Questions
What is the difference between weighted and unweighted GPA?
Unweighted uses a plain 4.0 scale. Weighted adds points for honors, AP, or IB courses.
Can a weighted GPA be higher than 4.0?
Yes. With AP A grades counting as 5.0, a weighted GPA can reach above 4.0.
Do colleges prefer weighted or unweighted GPA?
Many look at both, or recalculate on their own scale, and pay close attention to course rigor.
How do credit hours affect GPA?
Grade points are multiplied by credits, so higher-credit courses influence GPA more.
