The math stays visible.

GradeHorizon shows the assumptions behind the result so you can check them against your school’s policy.

Weighted courses

Honors adds 0.5 and AP / IB adds 1.0 to the base grade points, capped at 5.0.

Credit weighting

Each course contributes grade points multiplied by credits. The total is divided by all valid credits.
