How weighted GPA works

Each letter grade maps to a grade point on the standard 4.0 scale (below), then the class level adds a bump: +0.5 for Honors, +1.0 for AP or IB, the most common weighting in US high schools. Your weighted GPA is the credit-weighted average of those bumped grade points; the unweighted figure shown under the result skips the bumps, since colleges often recalculate both.

B-2.7D-0.7
C+2.3F0.0

Check your school's exact scale

Weighting isn't universal: some schools cap the bump for a failing grade, use +0.33/+0.67, or weight on a 5.0 scale outright. This uses the most common +0.5/+1.0 convention. Compare against your transcript before you quote a number on an application.
