What are my chances for getting into these UCs?!

<p>Right now in my Junior year, I have a 3.9 weighted GPA. In my sophomore year, I got 3.67 unweighted, not sure about weighted. I took a few honors classes (Chem.,Geometry, US History) and AP chinese (got a 5), and I'm taking AP environmental science right now. I'm the President of the Red Cross Club at my school. I am also in other volunteer clubs. I've done a few internships and am currently in youth development/leadership organizations for low income students. I've worked for a few jobs in an organization that's also for low income students. I took the PSAT and got 1300, I didn't study for it which is also why I got a low score. I'll be taking the SAT soon this spring. I hope if I study, I'll get at least 1500 which is average. I'm really stressed about colleges right now and I don't what more I could do besides having more EC's and studying harder.</p>

<p>The following are UCs and CSU that I really want to go to.</p>

<p>University of California, Los Angeles (My chances are probably 0 huh...)<br>
University of California, San Diego<br>
University of California, Davis<br>
University of California, Irvine (Really really want to go to this one)
University of California, Santa Barbara<br>
California Institute of Technology<br>
University of California, Santa Cruz<br>
University of California, Riverside (I really want to go to this one too)
San Diego State University </p>

<p>Please help, thank you :)</p>

<p>UCLA- Reach
UCSD- low reach
UCD- low reach
UCI- match (cousin is freshman there now, she was way less impressive than you)
UCSB- match
UCSC- match
UCR- match
SDSU-match (basically guaranteed)
High SAT scores will help a ton, aim for higher than a 1500</p>
