UNC Supplemental (Why?)

What is the point of this? Asking for transcripts and a bunch of other information that should already have been provided in the actual application. One of the schools I received credit from currently takes MONTHS to fulfill transcript requests.

Edit: Called the admissions office. I asked about the transcripts and the conduct questions (as they were both just different enough from the other application to warrant different answers and also requested substantiating proof) and was told that the law school only really cares about the residency question. Other questions should be answered truthfully but transcripts and substantiating documents are not required. I was also told that a difference in how I answered the conduct questions on the supplemental application and regular application shouldn’t be a concern.
