Hi Ryba... the wait list has generally been a year for the OU ABSN program. So if you are applying in Dec 2011, then you could expect to be accepted into either the December 2012 or May 2013 Cohorts. In previous threads, people did mention being bumped to an earlier cohort, based on last minute openings, provided they had their 5 additional D and E pre-req's completed (Micro, Lifespan, Informatics, Patho, ect).
What class are you taking this fall? I have my organic chem class at OCC- HL, and then I am also applying in Dec. ;-) Because of my personal schedule constraints, I am actually hoping to get into the May 2013 Cohort (should I be fortunate enough to get accepted!!!)
