At many CSUs, majors are impacted - meaning that you have to be admitted to the university, then to the major, and there’s a threshold one needs to pass in order to get that major. CS’s threshold at SJSU is VERY high. CSE is very high too but less so than CS, and math is accessible.
You can calculate your odds yourself.
