It all depends on the school(s) you're applying to and their deadlines. I was supposed to take the TEAS this past Saturday (7/21) but spent the week before in the hospital with kidney stones, had surgery and recovery and felt totally not prepared for it so I re-scheduled it for 8/15. According to my advisor, once I pass I can still be interviewed and start my general classes on 8/27 with a starting date of 8/2013 for the nursing portion which could also be as early as 5/2013. I would check with the school you're planning to attend. All programs vary.
