Regarding CSUs, they use the weighted-capped version of recalculated GPA like UCs, except that a semester college course taken while in high school counts as two courses and grades for CSU but one course and grade for UC.
CPSLO is very unlikely. So is SJSU, since the most recent admission cycle had a CS threshold equivalent to a 4.35 GPA (though students who will graduate high school in Santa Clara County get a bonus equivalent to +0.25 GPA). CPP had a threshold for CS equivalent to a 3.98 GPA for students with no additional points in its MFA model (unfortunately, the point value of such additions is not listed on the web site). SDSU does not seem to be transparent about prior year frosh admission thresholds.
However, many other CSUs, like SFSU, CSUEB, and others, are not all that difficult to get into, including for CS.
