there are 2 discussions going on right now about case and creighton - the thick packet (the one i was asking and posting about) was from case.
several weeks ago i got a large packet from case with brochures and a checklist that told me what they still needed from me for my application to be considered "complete".
today i received a thick, regular envelope inviting me to interview which contained instructions on who to call to set up the interview and other info. like the schedule and where to stay, etc. they are now booking interviews into the beginning of Oct.
hope that helps
