My guess right now is that they are giving II to the people who they think would most likely matriculate to the school taking into account stats and/or region. Example:
@fldoctorgirl - We have almost exactly the same stats but haven't gotten an II at the Erie campus. Our stats are higher than LECOM's avg. However, she got an II at Bradenton and maybe that's because she is from Florida and more likely to stay in the region. This is all just speculation btw. I have no idea how they send out II but that is my guess after observing who's been getting interviews. We may get interviews at a later time than the early interviewers so they have a chance to opt in to the early acceptance pool.
