First round acceptancees have 45 days to respond and place deposits. So if a school, such as Temple, sends out enough first round acceptances (200) to fill their class, you will have to wait until mid January for the second round. Of course not all 200 will accept due to multiple offers and seats will open up. Other schools such as ASDOH only send a few offers Dec 1 (I think 20). I would think they can send additional offers any time. It just depends on each school's system. Hope this helps. I'm sure others will reply with additional information.
Good luck to you. There's still plenty of time. I've met students who interviewed at Nova in Feb and were accepted.
