Grading System
San Diego State University uses a 4.0 grade point system. Faculty members use grades from A through F, with plus/minus gradations (A, A-, B+, B, B-, C+, C, C-, D+, D, D-, F), to distinguish among levels of academic accomplishment; SDSU does not award an A+. The grade for average undergraduate achievement is C.
SDSU reports Grade Point Average (GPA) to the second decimal place. No rounding up is done to increase the GPA above what the student has earned.

How Special Grades Affect Your GPA
Credit (CR) and No Credit (NC) grades are not factored into the GPA. For undergraduates, CR is awarded for work equivalent to A through C (2.0 or more grade points); NC is awarded for work equivalent to C- through F (less than 2.0 grade points). For graduate-level courses, CR requires A or B (3.0 or more); NC covers B- through F (less than 3.0).
Audit (AU), Report in Progress (RP), Report Delayed (RD), and Withdrawal (W) are not factored into the GPA.
An Authorized Incomplete (I) is not factored into the GPA but must be resolved within one calendar year; if not resolved it becomes an Incomplete Charged (IC), which counts as 0.0 grade points (or is charged as NC if the course was originally taken CR/NC).
Withdrawal Unauthorized (WU) is computed into the GPA as an F (0.0 grade points).
Grade changes are not made more than twelve months after the grade was issued, and not after graduation.
