What are his GPAs recalculated using the method here: https://rogerhub.com/gpa-calculator-uc/ ?
Based on the weighted-capped GPA, you can look at the past admission rates to UCs at http://talk.qa.collegeconfidential.com/university-california-general/2127392-faq-uc-historical-frosh-admit-rates-by-hs-gpa-2018.html . However, computer science is generally a more competitive major, so admission rates / chances should be expected to be lower for the same GPA range.
For SJSU and CSUs other than CPSLO, calculate the eligibility index as GPA * 800 + SATRW + SATM. GPA is the weighted-capped GPA from the above calculation. However, it looks like the student’s 33 ACT is much higher than the 1200 SAT; based on https://www2.calstate.edu/apply/eligibility-index/Documents/eligibility-index.pdf , it looks like CSU considers 33 ACT to be like 1510 SAT. SJSU’s past thresholds for admission are listed at http://www.sjsu.edu/admissions/impaction/ .
