Weighting rewards harder courses
A weighted GPA is a credit-weighted average where advanced courses earn extra points. The standard bonuses are +0.5 for honors and +1.0 for AP or IB, added on top of the normal grade value before averaging. Each course still counts in proportion to its credit hours.
What each grade is worth, weighted
| Grade | Standard | Honors (+0.5) | AP / IB (+1.0) |
|---|---|---|---|
| A | 4.0 | 4.5 | 5.0 |
| A- | 3.7 | 4.2 | 4.7 |
| B+ | 3.3 | 3.8 | 4.3 |
| B | 3.0 | 3.5 | 4.0 |
| C | 2.0 | 2.5 | 3.0 |
| D | 1.0 | 1.5 | 2.0 |
| F | 0.0 | 0.0 | 0.0 |
An F stays at 0.0 no matter the course type — a bonus is only added when points are earned.
Where weighting actually moves the number
- Credit hours are the multiplier. A 4-credit AP class shifts your average far more than a 1-credit elective. Full grade impact scales with the course weight.
- Failed courses stay in. An F remains in the calculation until a retake replaces it (where your school allows that). Dropping it out on your own inflates the result.
- Pass/fail usually does not count. Pass/fail courses satisfy requirements but are normally left out of the GPA, so they neither help nor hurt.
Common questions
What is the difference between weighted and unweighted GPA?
Unweighted GPA treats every course the same on a 4.0 scale. Weighted GPA adds a bonus for harder courses, usually +0.5 for honors and +1.0 for AP or IB, so an A in an AP class can count as a 5.0. That is why weighted GPAs can climb above 4.0.
How high can a weighted GPA go?
On the common system it tops out at 5.0, earned by getting straight A grades in all AP or IB courses (4.0 base plus a 1.0 bonus). Some schools cap the bonus differently or use a 5.0-plus scale, so check your own school's policy.
Do colleges use weighted or unweighted GPA?
Many recalculate your GPA their own way to compare applicants fairly, often stripping weighting or using their own bonus rules. Report the GPA your school issues, but know that admissions will usually look at course rigor separately.
