Please re read my post. I was responding to formerf1 who stated 2 of his DO OMS1 classmates applied to MD school while1st yrs and left after getting accepted. Do2021's post and mine will make more sense.With all due respect, you guys are not fully understanding how these combined programs work. OP wouldn't be taking a seat (or tuition) away from anyone! OP is asking about leaving a program AFTER completing the UG component and BEFORE starting DO. The school would merely fill that seat with a regular admission applicant. She wouldn't be leaving after matriculating in DO school, it wouldn't be considered unethical, there would be no reason to disclose it to other schools, other schools would have no way to know, etc. The issue is merely giving up a guaranteed DO spot to take a shot at MD. None of the other issues are in play!
