Are you currently a Posse nominee? Right now Posse is holding round 2 nominations. Students who get through round 2, go on to round 3 where they are eligible for Posse. Access if they do not make the finalist round.
First, as @sybbie719 asked - are you a Posse semifinalist? DAP 1 interviews should be over by now, and you should have received your notification for the DAP 2 interview date. However, keep in mind that, even if you are advancing to DAP 2, fewer than 25% of the semifinalists end up as Posse scholars.
Posse generally matches students to colleges which are within their “stats” range. So there is a good chance that Posse will not match you with ND (though that is not certain).
PS. since, if you are a Posse Finalist, but are not selected as a Scholar, you get a serious boost in being accepted to any Posse partner college, do look at Wooster.
