You can, and you should. I have. Knowledge is power in this game, and you need to get as much insight as possible. And believe me, the information you get may suck. I've been told by 3 of 4 schools that waitlisted me that it was likely my experience--something that was fixed before I even got to their interviews and well before match time. They received updates on the subject, even, and it seems like it was largely ignored.
I am a reapplicant, and may be a 2nd time reapplicant. Here's some advice: be confident. Don't show weakness in the face of adversity. If there's one thing I know can be sniffed out in an application/ interview it's the nervousness inherent in being rejected before. Come from a position of embracing that failure, coming to terms with why you haven't gotten in, and returning with the confidence that you are better suited to care for others' health than you were before. You want to show schools that you are even more driven than you were before, and that the set back has only made you stronger.
It's possible that in your feedback, the school just took a look at your original app and didn't even see the update --
Like your second paragraph and the positivity and message of confidence. One suggestion though: While I'd absolutely agree that it's important to show how well you're qualified this cycle (the one you're applying for), I'd suggest you not maintain that you were ready last cycle, as that implies the AdCom was wrong to turn you down before. (Even if you fervently believe they were -- no one likes to be called wrong.)
So focus on what you've improved, how you've grown, and that now you're ready --
