<p>While all top adcoms deny having feeder high schools there are certain schools that have multiple students accepted every year while other high schools have not had a student accepted in 20 years. Students from about 20-30 percent of US high schools have next to zero chance of meeting the profile needed to gain admission. These tend to be in low income urban and rural areas. When you look at the high schools with annual success in placing students in top universities they tend to be elite privates, magnets and top publics in affluent suburbs of large metro areas. Where you live and attend high school does matter.</p>
