@northremembers: SJSU lists the Eligibility index thresholds for Freshman or GPA for Transfers from the previous year by major to give applicants an idea of how they may fare in admissions. SDSU lists the # of applicants/#of admits/# of enrolled by major each year so you can determine the acceptance rate.
Unfortunately, I have not been able to find comparable data for CSUN or CSULB.

The link below does not give information by major, but it gives enrollment information along with average CSU GPA/Test scores, local vs non-local cutoffs etc… for each campus.
