UCs all use holistic review, although the effect of HS GPA gets stronger relative to other factors when going down the selectivity range (because HS GPA becomes more of a differentiator among applicants, as opposed to readers having to make distinctions between applicants clustered at the top of the HS GPA range).
CSUs all use some kind of point system, but each campus can choose its own point system, and not all campuses are transparent about what their point system is or what past thresholds were.
