Princeton's legacy admit sure is high.

"As a case in point, Princeton University's overall admissions rate dipped below 10 percent last year, but 40 percent of legacy applicants were admitted to the Class of 2012, according to an April 2008 ABC News report. Though the practice may be generally accepted among prestigious universities, it has drawn some criticism, particularly from students who do not benefit from it."
