How important are prereqs for a Psychology major at Cal States?

My GPA is about 3.1 and I have completed the IGETC.

Which Cal states are you targeting? What pre-req courses are you missing? What is your local CSU?

How does your GPA compare to your target schools? https://www2.calstate.edu/attend/counselor-resources/Documents/transfer-2019-admission-impaction-chart.pdf

I’d plan to compete anything listed as required - especially for the impacted campuses.
