Living in Irvine is neither an advantage, nor it is a liability when it comes to the college admissions, generally speaking (however, there might a bit of reverse discrimination against Asian American students in college admissions: being Asian in Irvine is somewhat a liability, as you need to work even harder). Admissions officers at top universities are very familiar with each Irvine school and know exactly the "type" of the student they are looking for, how many they admitted in the past and how many they will be admitting this year. They are familiar with high quality of Irvine schools, so they respect them. They compare apples to apples: e.g. top Irvine kids with other top Irvine kids (relative to their background). You gotta work hard, no matter where you are. Also, depends on a major. Computer science/engineering vs. Language Arts - that's another admission criteria, and GPA requirement differs from major to major. Personally, I think secondary school education (even in Irvine) is far below European and Asian standards, so I would not rely on public school curriculum too much to prepare kids for top college admissions.
