Listen, if you have done absolutely nothing between Year 1 and Year 2 of applying then you are wasting a year of application including a buttload of money because there will probably be no school that will take you if you have done nothing to improve your application.
As a reapplicant, you are most probably not the highest on the list, however, you need to sell yourself as the best thing for the school...how? In your extra year you A)got better grades, better MCAT, etc, B) some sort of work experience or volunteer experience or gotten some sort of experience, or C) the extra time has made you a better person/applicant because of some special thing that happened.
Again, if you've done nothing to improve your app, you are wasting your time
