How is GPA calculated?

GPA = Σ(grade points × credits) ÷ Σ credits. A grade points: A+/A = 4.0, A− = 3.7, B+ = 3.3, etc., F = 0.0.

How is the weighted bonus applied?

Honors classes add 0.5 to the grade points; AP/IB classes add 1.0. The bonus is not applied to F grades.

Does the calculator handle quarter / half credits?

Yes — credits accept any positive number, so 0.5 / 0.25 / 1.5 work. Negative or 0 values skip that row.

Are my grades stored anywhere?

No. The calculation is fully client-side. Refresh and they’re gone.
