Once I think about it maybe you can try a hybrid approach - tell them you are on the fence about attending law school due to legal jobs market, then write a letter stating that, highlighting your advantages (whatever you got, community service, GPA, leadership, etc) and asking to be considered for more money. Then you can sit back and wait till the very last week to make a deposit. If they did not give your money, oh well, u r in anyways and you did all you could.
