How does dual-enrollment weighting work?

Dual-enrollment (and AP/IB) courses often receive a grade-point bonus to reward their college-level rigor. On a 4.0 scale a common bonus is +1.0, so an A in a dual-enrollment course is worth 5.0 instead of 4.0 in the weighted GPA.

What is the difference between weighted and unweighted GPA?

Unweighted GPA caps every A at 4.0 regardless of difficulty. Weighted GPA adds a bonus to honors, AP, IB, and dual-enrollment courses, so it can exceed 4.0. Colleges often recompute GPA their own way, so reporting both is useful.

How is the GPA weighted by credits?

Each course's grade points are multiplied by its credit hours, summed, and divided by total credit hours: GPA = Σ(gradePoints × credits) / Σ(credits). A higher-credit course influences the GPA more than a lower-credit one.

What bonus should I enter?

Check your high school's policy. Many add +1.0 for dual-enrollment and AP; some add +0.5; some add nothing. Enter the actual bonus your school uses so the weighted GPA matches your transcript.

Are failing grades counted?

Yes. An F is worth 0.0 grade points and still counts in total credits, which lowers your GPA. The bonus is not applied to failing grades because there is no positive value to boost.

Calculate your dual-enrollment GPA

Students taking dual-enrollment college courses alongside high school classes often have two GPAs: an unweighted GPA that treats every A equally, and a weighted GPA that rewards the rigor of college-level work with a grade-point bonus. This calculator computes both from your full course list, so you can report whichever a given university expects.

How it works

Each letter grade maps to standard points (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0). The unweighted GPA is the credit-weighted average of those points. For the weighted GPA, dual-enrollment courses receive a bonus you specify (commonly +1.0), but only for passing grades:

weightedPoints = basePoints + (isDual && passing ? bonus : 0)
GPA = Σ(points × credits) / Σ(credits)

Tips and notes

Use your school’s published bonus value — a +1.0 bonus and a +0.5 bonus produce noticeably different weighted GPAs.
Higher-credit courses pull the average harder, so a strong grade in a 4-credit course matters more than the same grade in a 1-credit course.
Many universities recalculate GPA from your transcript with their own rules. Keep both figures handy for applications.
