How Cal Poly SLO Calculates GPA

California Polytechnic State University (Cal Poly SLO) uses a 4.0 grade point scale and uses plus/minus modifiers (A-, B+, B-, and so on). The school caps A+ at the same 4.0 value as an A, which matters when converting letter grades from a transcript that records A and A+ separately. Each course's grade points multiply by its credit hours, those quality points sum across all courses, and the total divides by total credits attempted.

Cal Poly SLO GPA Formula

GPA = Sum(Grade Points x Credit Hours) / Sum(Credit Hours)

Where:

Grade Points = letter-grade value on the 4.0 scale
Credit Hours = credit value of the course on the Cal Poly SLO transcript
A+ = 4.0 (same as A on the standard scale)

Example: A 4-credit class with an A (4.0 points) and a 3-credit class with a B+ (3.3 points): quality points = 4 × 4.0 + 3 × 3.3 = 25.9, total credits = 7, GPA = 25.9 / 7 = 3.70.
