Upward trend in grades for UC AND PRIVATES

To give you guys a little perspective. My freshman year GPA was a 3.4. My sophomore year GPA was a 4.2 and my junior year GPA was a 4.9. I attend a competitive high school and I have managed to become top 2 percentile for 10-12 GPA with a 4.57. How would colleges reflect on this GPA, do I still have a chance at some top tier privates or UC?

Oh my 9-12 gpa is a 4.13 now btw

When UCs recalculate HS GPA, they include 10th-11th grade course grades. Up to 8 semesters of honors or AP courses are given +1 weighting points (see https://hs-articulation.ucop.edu/agcourselist for which courses at your high school are considered honors).

How about for top tier private schools.
