Agree with @MYOS1634 statement regarding SLO and ED. The RD pool is usually more competitive, since many top students will use SLO as a Match/Safety school while you can get into ED with a little less than superior stats. SLO usually fills 1/3 of their in-coming Freshman class from ED applicants. Also not all majors are created equal at SLO, where some majors with greater than 90% acceptance rate and anyone applying with decent stats has an excellent chance for an acceptance.
