I certainly remember the anxiety-provoking nature of the match process. I felt like I didn't know where I stood with regards to several programs, whereas others were very forthcoming about sending "we want you" letters. Looking back on it now though, I realize that this isn't really a legitimate concern from the standpoint of the match itself. Sure, it's enough to drive you crazy when you're going through it, and for that reason it really sucks, but if you properly understand the match algorhythm then it really shouldn't matter at all in the grand scheme of things.
The way the match works, there's NEVER a reason to order your rank list based on anything but your own personal preference. Even if you think you have only a snowball's chance in hell of matching at your dream program, you should still rank it #1 if it's clearly your top preference. Whether or not they send you a love letter shouldn't make a shred of a difference, because the match algorhythm favors YOU, the applicant, in that way. If they don't rank you at all then you won't match there, but this also won't hurt your chances of matching into your #2 program. That's why you should only order your list in terms of where you'd most like to go, regardless of anything you think they implied, or said in a letter. Please please please don't read into these letters...they mean nothing! The only thing that matters is where you rank them, and subsequently where they rank you. Don't fall into the trap of re-ordering your list based on communications from programs...there's a reason why they're not allowed to say much per the NRMP rules, and it's because of this very problem that the rules were developed. Otherwise the process could become unfair, and would defeat the whole purpose of the match.
Just relax and enjoy the remainder of 4th year, because you'll never have a schedule this great again!
