Also, do LORs stay in the LSAC system? Could I use the same ones if I reapplied next year or would I have to resend them? That would make me feel bad to ask my profs to rewrite them when they JUST wrote them two months ago.
Your LORs will still be available to resend via your LSAC account if you decide to reapply. I think they keep them for a few years, but I'm unsure of the specifics. You could probably use the same ones again, but I'd check with the particular school about whether they want new info or not before you go ahead with app #2 (if you decide to).
