To fairly compare CP SLO to UCs, I use mid GPA & SAT from 2017 admission and calculate MCA (GPA & SAT only)
MCA (GPA & SAT only)
UCB 3694
UCLA 3694
UCSD 3631
CP SLO 3599
UCSB 3573
UCI 3558
UCD 3547
Keep in mind CP SLO use Super Super Scoring for std test, so number still inflated here ! Best guess is that CP SLO in same league as UCSB, UCI & UCD.
High school teachers have lots of influences here. My D’s AP calc & STEMs classes teacher all from CP SLO & convinced her CP SLO is great school even though she has never visited campus.
