Frequently asked questions
How is GPA calculated?
GPA = Σ(credit hours × grade points) ÷ Σ(credit hours) — each course's grade points are weighted by how many credit hours it's worth.
Does every school use the same 4.0 scale?
Most US schools do, but the exact grade-to-point mapping (e.g. whether an A- is 3.7 or 3.67) can vary slightly — check your registrar's official scale for anything that needs to be exact.
