Welcome to College Confidential.
There is really no way to chance you based on your posted information. If your unweighted GPA translates correctly, then you can be competitive for the UC’s and SDSU.
You will be considered OOS for the SDSU and the UC’s, so you will be paying non-resident costs.
SDSU mainly admits based on GPA, HS course rigor, # of the CSU a-g courses taken beyond the minimum’s, preparation for major (classes/grades), local admission area status and first generation. Cost of attendance for Non-residents was $54K/year. You are eligible for Federal aid but not California state aid.
The UC’s use 13 areas of criteria for their application review. First-year comprehensive review
Academics are only part of the admission process so a lack of EC’s can impact your chances however, if circumstances prevented you from participating in EC’s, that should be addressed in your application. Also your PIQ’s can be very important and present an overall picture of yourself outside the academics.
Psychology is a very popular major and can be impacted/selective at several campuses. Several UC campuses are definitely options for you.
Cost of attendance for Non-CA residents was around $84K/year and unfortunately the UC Regents just recently voted to increase tuition over the next few years.
What is your career goal with a Psychology or Child development major? Graduate school is usually required for Psych majors so you should also consider graduate school costs in your college budget.
You can look up UC admission rates by campus and discipline here:
SDSU’s Psychology is the most applied major and had around a 27% admit rate. Child Development was around 45%.
Best of luck.
