Just curious, but where are you doing 1L? You have some random schools posted. Keep in mind that if you go to FSU, it might be more difficult to get to USC/UCLA than from Southwestern or Arizona. There can be a bit of a geographic bias in that some schools have a "feeder" type deal with better schools. Not that this means there is any great disparity in GPA, but it could give a little extra leeway. Case in point, transfers from my school get into one private T20 more easily than another because one knows what our T4 is like.
Figure out what geographic area you want and then work your 1L year like you've never worked in your life. Also, if you want NYU and Columbia, you're going to need to get started on the paperwork process earlier than last minute.
