GPA used by UCs and other schools

@ucbalumnus:
That’s good to note that they look at all 3 variants of GPA. Yes, I did take a look at that website – thanks.
I am also wondering if extra ECs (Varsity sports, Club presidency, voulnteering) would also play a major part in the consideration of a candidate. My son is kind of an all rounder and has been maintaining a decent GPA (with a rigorous load of courses) in addition to playing and volunteering. Like as of now, his UC GPA is 3.85 and Weighted GPA is 4.25 – wonder if there is a channel for such GPAs amidst a lot of activities at school.
We are now getting stressed out not knowing how the colleges would look at his application…
