I think I posted something along these lines somewhere on this site a little while ago, but what the hey, I'll do it again. I got a DUI in 1998 and was suspended for a semester in 1997 due to alcohol-fueled mayhem. So far I got 3 acceptances, 1 reject, and 1 waitlist. My numbers were pretty strong for the schools that did not accept me, so I'm not sure if my record was significant or not. While this is just a hunch, I suspect the adcoms will overlook youthful indiscretions w/ booze but a tiebreaker might go to an applicant with a clean slate. I would think like the other poster said that it helps if a lot of time has elapsed- a recent DUI charge woud be cause for serious concern. Best of luck with your apps.
