GPA Capped And Weighted: 3.89
GPA Unweighted: 3.72
ACT: 36
SAT subject tests? EC’s? HS course rigor? Are you truly a Senior since some of your other posts indicate otherwise (question about retaking classes)?
Your capped weighted UC GPA is below the 25th percentile but your ACT is excellent. What is your fully weighted UC GPA?
UC’s tend to be very GPA focused so I would say at least 50/50 chances just based on your academic stats.
Since History is in the College of Letters and Sciences which admits by Division and not major, you will be competing with all applicants in that Division.
2018 Freshman admit rates for UC GPA of 3.80-4.19 capped weighted and not major specific:
UCD: 41%
2019 UC capped weighted GPA averages along with 25th-75th percentile range:
UCD: 4.13 (4.00-4.26)
25th - 75th percentiles for ACT composite + language arts
UCD: 24-33
based solely on your stats, probably not but there’s some subjectivity to UC admissions so, a compelling application and strong ECs could get you in.
Good luck
