SDSU accepts applicants based on their major and Eligibility index. EI= (CSU GPA x 800) + (SAT Math + CR).
Your EI is 3900 if your CSU GPA is 3.5. A competitive EI is around 4100+ so you are slightly below that level. SDSU would be a High Match.
Race will not be considered in your admissions decision since the California publics banned affirmative action.
Economics had around a 35% acceptance rate so it could go either way.
Good Luck.
