If you look the the MCA points (which may be different than posted for this year) for SLO, HS course rigor and some non-academic areas such as being local have large point values.
Class rigor score, worth 750 points. In this section you get zero points for meeting the minimum admission requirements and adders for more than the minimum. The bonuses in order of power are (min semesters/max total semesters/bonus per extra semester/total possible bonus): math 6/10/125/500, lab science 4/8/50/200, English 8/10/50/100, foreign language 4/8/25/100, visual performance 2/4/25/50, no bonus points for social sciences or electives. As with GPA, you can actually score higher than the maximum, but 750 is the most they will count.
Finally, work and ECs, worth 350 points. Work (hours per week/bonus): 0/0, 1-5/20, 6-10/40, 11-15/60, 16-20/80, 21+/100, add 50 points if work is major related. ECs (hours per week/bonus): 0/0, 1-5/30, 6-10/60, 11-15/90, 16-20/120, 21+/150, add 60 points for leadership role.
There are also other Non-Academic Bonus Points:
CA vet/701, Hayden Partner School/700, faculty/staff dependent/700, service area of CP/500, either parent with some or no HS, but who DIDNāT GRADUATE FROM HS/300 (per parent).
Being local gives all CSU applicants an admission bump, so unfortunately lower stat local applicants can be admitted over higher stat non-locals which is true for CPP and SLO.
