chances, weird case please read

<p>How many UC's can I appy for? I have a singaporean passport and an american passport. Do I count as Chinese? I learned most of my chinese in highschool...could barely speak or write before high school, only could understand. I learned ALOT due to term abroad and my teacher. will colleges count that SAT as less? I speak english at home and all.
If i go just to a public high school, my GPA will be alot higher, but then my ECs would be all screwed up. No chances at being a president of any club whatsoever. Is that worth the trade?
Also thinking of going half high school+community college classes for credit. Is that a good option? College counseling staff here at Choate isnt too good....alot of new people this year because everyone left last year due to better job offers, fired, etc. Plus they dont know too much about Cali cuz 99% of the kids at my school apply for non west coast schools except for Stanford. No one on east coast applies to Berkeley for instance.
How many UCs can one apply to? I heard you can only apply to 4.
I'm very uninformed as you can see. This forum is great for answering my questions without needing to wait 1 week to schedule an appointment with a college counselor.</p>
