1) If you reapply the cycle after you applied the first time, and are pretty sure that you have solid LORs, do you need to get new letters? new reccomenders?
2) How much do you need to change your P.S. if you're applying to the same school as the first time? Completely redo? minor tweaks?
3) Are fee waivers easy to ask for at IU, NU, UChi, Michigan, ND, and Illinois (assuming it's not free for everyone again)?
For 1 and 2, I am virtually positive that I didn't get dinged because of either of these factors. While my PS wasn't out of this world, it was well written and pretty solid, and my recommenders really liked me, so I'm positive that neither wrote anything disparaging.
Any help would be great, and any anecdotes about getting in the second time around would ease my qualms about the whole putting my life on hold thing

Thanks
