Hi. I am a soon-to-be third year KCOM student. I was placed on hold, thought I was doomed to being a high-school teacher and then outta nowhere was called and invited to interview in June. I came up and interviewed, all the while assuming that I was interviewing for a wait-list spot. 3 days later, got a phone call saying I was accepted.
There's no way of knowing how it came to be that you were contacted. It could be that some folks who originally accepted have very recently backed out, or something like that, making room in the class for a few more. If you wanna be accepted at KCOM, this is a great opportunity.
Good luck.
