I was accepted to USUHS back in Oct. Since then I have gotten into another medical school and have been waitlisted at severl others. I have not decided exactly which schools of the ones I interviewed at I want to attend. My question is up to what point can I pull out of USUHS. Officer training starts June 16th and the school itself starts August 12th. If I get selected off a waitlist another school in July for example, can I decide to attend that school, eventhough I started Officer Training?
