At the Thurgood Marshall Academy for Learning and Social Change, a public school on West 135th Street in Harlem, every one of the 82 members of the senior class is expected to apply to college. At a suburban or private school, or at a wealthier city school, these seniors would have all the help they need. They would have been raised in families where going to college is a given. They would have advisers who know about a wide range of colleges and have contacts in admissions offices. They would take test-prep courses and rewrite their personal essays numerous times with the help of a savvy editor. They would have a list of deadlines to meet and be constantly pushed to meet them by parents and school advisers.
