Depends on the weighting system.
UCs and CSUs count college and AP courses as honors with +1 (and CSUs count a college semester like two high school semesters). Both calculate GPA over 10th-11th grade courses and have a cap of 8 semesters of honors +1 points (UC also calculated unweighted and weighted uncapped).
Other colleges may use different methods if they recalculate GPA.
