I see that this is an old thread, but for the benefit of other readers, @blossom is right that students in this situation should tread with caution.
There are some students who can make a wise decision to go to a low-ranked law school, but that depends on the cost, career goals, etc. CUNY Law has incredibly low tuition and a great track record of launching students who want to do public interest work in NYC. If you want to be a prosecutor in South Dakota, the University of South Dakota Law may be an excellent choice. If you get a full ride at a 4th tier private school, that may bring the cost-benefit analysis into a very different space. If there’s a job waiting for you at your uncle’s divorce law practice and you just need a law license, then where you go to law school may be almost irrelevant.
Most students, though, don’t have that kind of plan and are risking their futures when they take on debt to go to a low-ranked law school.
