Depends on the school. Texas and Florida are notorious for encouraging in state students and being very hard on out of state applicants. Other schools, like Wisconsin, charge full freight for all out of staters, because they are a seller school and don't need to offer aid to get out of state attendees, but they still prefer instate kids as a mission.
Maryland on the OTOH, lives and dies off of full freight NJ kids (as does Penn State), so they tend to be very fucking choosey about their instate acceptances. If you are a middling student from central NJ, getting into College Park is a breeze. If you are a high achiever from Montegomery County, Maryland, it's fucking brutal getting a yes from Maryland. They need that out of state money. For somewhere like Oregon, they literally can't get enough in state bodies to fill up UO and OSU, so they have to entice California, Texas, and Colorado kids with financial aid packages.
