Key facts
GPA = Σ(grade points × credit hours) ÷ Σ credit hours
Grade scales
Letters are worth 4 points for A, 3 for B, 2 for C, 1 for D and 0 for F. Plus and minus move a grade by 0.3 on the one-decimal scale (A− = 3.7) or by a third on the thirds scale (A− = 3.67); pick the one your school uses.
Pass/no-pass courses are left out of the GPA, as most schools do; their credits are listed separately.
