GPA is a credit-weighted average: GPA = Σ(grade points × credits) ÷ Σ(credits). Convert each letter to grade points first (A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, C = 2.0, and so on). With four courses worth 4.0, 3.0, 3.7 and 2.0 grade points and 3, 4, 3 and 2 credits: (4×3 + 3×4 + 3.7×3 + 2×2) ÷ (3+4+3+2) = 39.1 ÷ 12 ≈ 3.26. Set a course's credits to 0 to leave it out.
Questions
How is GPA calculated?
Multiply each course's grade points by its credit hours, add those up, then divide by the total credit hours. It is a weighted average, so courses worth more credits count more.
How do I turn letter grades into grade points?
Use your school's scale — typically A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C = 2.0 and so on — then enter those grade-point values for each course.
What if I have fewer than four courses?
Set the credits for any unused course to 0. A course with zero credits drops out of both the weighted total and the credit total, so it does not affect the GPA.
