Re: second choice major at SJSU
On https://www.sjsu.edu/admissions/impaction/freshmen-impaction-results/index.php , majors listed with ^ are those which did not have capacity to admit those listing it as an alternate major. For 2020 admissions, it looks like all majors that had EI thresholds of 3100 or higher (including software engineering) were marked as such, while most (but not all) majors with EI thresholds of 3000 or lower were marked as such (applied math computational had an EI threshold of 3000 but did not admit alternate major applicants).
