SDSU does not accept any essays or personal statements so I do not know where you saw that they do?
The application for the Cal states including SDSU does not open until October 1, so I do no know what you are referencing?
SDSU admission factors:
MULTI-FACTORED ADMISSION: Due to not requiring test scores, we no longer use an Eligibility Index per se. Instead, as an impacted campus, admission is based on many factors. Weighted CSU GPA is the largest factor, but we also consider amount of A-G courses above and beyond the minimum, preparation towards intended major (courses and GPA), HS course rigor, first-gen, and local status.
For the Cal states, you have to apply using the CSU application. On the CSU application, some campuses will have additional questions listed under the Program Materials section. You do not list your EC’s on the CSU application. For example, Cal Poly SLO will ask about how much time you spend on your EC’s with hours/week, ask if you held any leadership positions, if you have a job and is it major related. There is no where you can go into detail about your EC’s or specifically list them.
For the Cal States, they admit based on CSU capped weighted GPA, HS course rigor, # of a-g courses completed, if you are within the local service area and if you are considered first generation as noted by the SDSU factors.
Some schools have Impaction indexes or MFA index/thresholds based on majors such as SJSU and Cal Poly Pomona where you can plug in your stats to see if meet or exceed the previous year’s major thresholds.
