UW gpa: 3.34 (using UC calculator on rogerhub)
SAT: 1240 (660 reading/writing 580 math)
I plan on applying to UCSC and UCR, planning to major in psychology!!
I wanted to add UCSB and UCD but since those two are really big reaches, I don’t know if I’m going to include them, I just wanted a wide range of schools.
I have many leadership activities/extracurriculars that I’m also going to mention in the app :0
Why aren’t you considering the CSU’s?
UCSD and UCD will be reaches.
There are already CSUs on my list, this was just my school choices for the UCs! 
Here is the Freshman admit rate for your UC (capped weighted) GPA range and not major specific:
Freshman admit rates for UC GPA of 3.00-3.39
UCB/UCLA/UCSD: 1%- Super High Reach
UCI/UCSB: 2%- High Reach
UCD: 4%- High Reach
UCSC: 18%- Reach
UCR: 38%- High Match/Low Reach
UCM: 67%- Match/Low Match
Your SAT is solid but UC’s are very GPA focused. Having good essays and EC’s can help your chances but I would only apply to UCR/UCSC and not waste the application fees for the rest.
Add UC Merced if you are not ELC eligible.
25th - 75th percentiles for SAT:
UCB: 1280-1490
UCLA: 1280-1500
UCSD: 1250-1470
UCSB: 1290-1450
UCD: 1190-1430
UCI: 1190-1420
UCSC: 1170-1380
UCR: 1090-1310
UCM: 1020-1230
Best of luck and make sure you have at least one safety school.
i think UCR and UCSC are long shots. Be sure to also apply for Fullerton, Chico, Sac or another Cal State that’s likely to accept you.
good luck
