For freshmen, CPP uses the same Eligibility Index as the rest of the CSUs - which combines your CSU GPA (just a-g courses from grades 10 and 11) and test scores (SAT M&R Superscore or composite ACT). They rank applicants, taking the highest scores first and stop when the seats are full for each major. They also manage the waitlist top to bottom, admitting the most qualified first. (random must refer to ties).
They are also the ONLY CSU that will admit you with your fallback major. So, put a less competitive major as a plan B.
