For SJSU, past admission thresholds are at http://www.sjsu.edu/admissions/impaction/ . For frosh, they are based on the eligibility index of GPA * 800 + SATRW + SATM. GPA is recalculated like the UC weighted capped recalculation (handy calculator at https://rogerhub.com/gpa-calculator-uc/ ). CS has been the most competitive major at SJSU for the last few years.
UC past admission rates by weighted capped GPA are listed at http://talk.collegeconfidential.com/university-california-general/2127392-faq-uc-historical-frosh-admit-rates-by-hs-gpa-2018.html . But note that CS is often a more competitive major.
