Frequently asked questions

What's the difference between weighted and unweighted GPA?

Unweighted GPA uses a straight 4.0 scale regardless of course difficulty. Weighted GPA adds bonus points for harder courses — this calculator uses the common convention of +0.5 for Honors and +1.0 for AP/IB, though exact bonuses vary by school.

Why isn't my GPA matching my school's official calculation?

Schools vary in their grading scales, weighting bonuses, and how they handle repeated or transfer courses — for anything official (transcripts, applications), use your institution's own calculator.

A simple 4.0-scale GPA calculator gets weighted courses wrong — this one asks about Honors and AP/IB explicitly

Straight 4.0-scale calculators can't tell an AP class from a regular one, which is exactly the accuracy problem colleges warn about with generic GPA tools.
