The UC’s have a unique way to calculate GPA. As an International, I would go by the unweighted GPA meaning your regular GPA without weighted classes such as IB/AP/Honors. The UC GPA calculation gives you 8 extra honors points for taking AP/IB/Honors approved classes which will make the GPA above the 4.0 mark. I linked the UC GPA calculator if you want to try and calculate your UC GPA in my above post ^^. You need to take the SAT or ACT test scores to apply to the UC’s. I gave you the UC requirements for International applicant link so make sure you meet these requirements. GPA alone will not get you into these schools. You also need to meet the a-g course requirements and English proficiency.
For UCLA, you want to have a unweighted GPA of 3.85 or higher. Here is another link that shows the statistics for in-coming Freshman from last year. http://www.admissions.ucla.edu/prospect/adm_fr/Frosh_Prof14.htm
