OOS students pay full fees for California public schools; that’s $55k per year, and as an OOS, you cannot gain instate residency if you come to California for educational purposes.
Additionally, OOS students are typically surprised by the “F” requirement of one full year of visual/performing arts in a graded classroom. http://www.ucop.edu/agguide/a-g-requirements/f-visual-performing-arts/index.html
Use the link to calculate your UC GPA. OOS students can only use AP and IB classes for extra weight. You cannot use OOS honors courses for extra weight.

Your SAT and ACT are not competitive for UCLA, sorry.
