Well, the only thing I remember was in Chicago we have selective enrollment high schools that you have to test into. They are the creme of the crop schools. They do make it easier for kids/families from the South and West side to get in then North side families that tend to live in a wealthier district.
So the story goes that multiple families would buy a condo in a less wealthy district and use it like a home base to basically lie to where they live. Many got caught. Kids that live on nearby suburbs also lie to try to get their kids in…
So I guess they can pass that on to colleges also.
