many rolling schools will give out acceptances around oct. 15th ish at the earliest. there is a rule set by the AAMC that prevents schools from getting back to you with an acceptance before that (unless you apply EDP).
so, check out any rolling schools that sound like a good fit for you and get your secondary apps in by end of july. then you'll be set to start interviewing in august/september and hearing back in october.
come to think of it, most schools are rolling i think (?). i can only think of a handful that are truly non-rolling and don't get back to their applicants until march (harvard, yale, upenn, duke...). but yeah the school i heard back from the fastest was my state school
