What is the best way to get feedback/output from my personal statement?

I don’t really have anyone that understands me of why I want to apply to a University of California.
I’m pretty much alone in this. My parents don’t even know what UCLA or UC Irvine is.

I’m in a really similar situation.

I would suggest your counselor, HOWEVER, there exist counselors that aren’t really knowledgeable in that topic.
For example, I live in an rural area with (not the best) educators and counselors. They dont even know what Olympiad competitions are, and they would suggest the local community college as a good college to go to.
So. . . Yeah. . . You should talk to your counselor if you really know that they can help you.

Sorry I didn’t really answer the question, but I hope it helps.

Do you live in California?

Yes, I do.
