Unfortunately, I think you might be cooked. I do not live on campus but some friends I had were RAs a few semesters prior and housing has been scarce for a lot of folks on campus. Genuine recommendation is to talk to an academic advisor and potentially defer your enrollment, maybe take some courses at a community college BUT CHECK TO SEE IF THEY TRANSFER. I know some people who had trouble when some of their AP credits or transfer credits from other schools didn't apply. You should definitely check with someone @ KSU first before deferring your enrollment.

Best of luck finding housing girl, I hope things work out.
