Just read any good osteopathy book. Know about the history of osteopathy. They didnt ask me why I applied to both allo abd osteo schppls but they did bring up the issue with other candidates.
Hope that helps,Goodluck
They didn't ask me anything about Allopathic schools. They do want you to know the history of Osteopathic Medicine. My interview was REALLY laid back , but don't let that fool you . My wife's interviewers tried to drill her on everything from MCAT scores to Marfan's syndrome. Oh well it really didn't matter because we both got accepted . Just relax and be yourself. If they try to drill you, know that it's nothing personal, they just want to see how you react under pressure. Hope this helps. Good luck!!!
