^ Acceptance to the University is based solely on the applicant's UPCAT performance called the UPG. All applicants are ranked from highest to lowest based on their upg's. At a certain point a line is drawn delineating the number of applicants the University could absorb given its resources (facilities, approved budget, personnel, etc etc). It is only when an applicant receives his admission letter that his economic stature comes into play...should he wish to apply for aid in the from of STFAP, etc etc.
In no way prior to taking the UPCAT, the main determinant of admission to University, does one's socio-economic stature came into play. Admission to UP depends on how much gray matter there is between your ears...and should remain as such. Whether one can financially sustain your studies in UP is a different matter all together.
