Legal Insurrection: "New York’s ‘Free’ College Tuition Program is Unworkable."
In addition to all sorts of provisos to get the money in the first place, students are required to stay in New York for as long as they got free tuition. (Room and board and fees are not included). Massachusetts has a similar system where students who graduate in the top 10% of their class don't need to pay tuition in a state school such as University of Massachusetts. To compensate for low/no tuition, the state schools mark up the room and board and other expenses that cannot be avoided.
