You’ll hear both sides of the fence. One of my advisors at CCC suggested that being a non-traditional student would hinder my chances of being accepted to any UC, and that maybe I should try my luck at the low-tier UCs or just stick to the CSU system. Since I’ve got accepted to all the UCs I’ve applied to, included Cal (non-trad, international student), I’m biased to think that being a non-trad does not hinder one’s chances at all. However, I think it’s important that you fill out the reason/circumstances of the gap in your education and write about your personal growth and your motivations to attend UC Berkeley. GPA is important (mine was 3.95), few ECs due to being married with a kid as well. But I heard that people in admissions have a “holistic approach,” perhaps to ensure diversity. If that’s true, my advice would be to work hard in your essays and to try maintaining your GPA is in the range (what ^^ ucbalumnus posted). Good luck!
