Congratulations on having a wonderful academic profile.
I will only address the California UC’s in this post. First of all, I am sure you are aware that the UC’s are test blind so your SAT score will not be considered for admissions or scholarships, only course placement.
The UC’s calculate out 3 UC GPA’s: unweighted, capped weighted and weighted uncapped so here is the calculator:
You state that your Dad is a CA resident, so using the Condit Bill, you receive a conditional waiver of Nonresident Supplemental Tuition for one academic year if you are the dependent child of a California resident parent. You as a student must have continuous enrollment and your parent must have established residency in California for tuition purposes. At the end of the conditional year, then you must meet the full residency requirements to continue paying in-state tuition. Just remember that you will receive the in-state tuition rate but you are not eligible for any other California state aid until you establish permanent residency.
For UC Berkeley and UCLA, Political Science/IR majors are found in the College of Letters and Sciences which does not consider major choice in admission decisions.
UC Berkeley’s social science majors had around a 9% admit rate while the College had an overall 15% admit rate. Campus GPA admit ranges (25th-75th percentile) were as follows:
Capped weighted: 4.15-4.29. Unweighted: 3.90-4.00 and Weighted Uncapped: 4.32-4.68.
UCLA’s College of Letters and Sciences had an overall admit rate of 11% and Social Science majors had a 9.3% admit rate.
The Weighted Uncapped GPA admit range (25th-75th percentile) was 4.41-4.76 and the campus Unweighted was 3.95-4.00 and Capped weighted at 4.2-4.30.
UCI admits by major so the Political science major had a 37% admit rate and International studies had a 50% admit rate. Campus GPA ranges (25h-75th percentile) were Capped weighted 4.04-4.27 and Unweighted: 3.84-4.00. Weighted uncapped not disclosed.
Overall you are a competitive applicant and best of luck with your chances and hopefully the affordability factor.
