For help with calculating your Cumulative GPA, please refer to the GPA Calculator Sheet which can be found online at http://www.sonoma.edu/advising/gpa/.
If you want to do it by hand, first, just look at the courses you have completed for a letter grade in your lower and upper division major requirements. Add up the grade points earned from ALL COLLEGE level coursework (on the Sonoma State University transcript this shows up under the PTS (points) column). Divide that number by the Units Attempted from ALL COLLEGE level coursework (on the Sonoma State University transcript this shows up as UNIT). Cumulative College grade point average (GPA = Grade Points ÷ Units Attempted).
