I COMPLETELY DISAGREE with number 2 bolded above.
Depends on where you are applying. Sometimes they say if you reapply and improve what you had weaker at many schools you have a higher shot then someone who is in a similar situation who applied the first time.
I've seen this true in Fl. many times. Really depends on the school. Some schools like Harvard and loyola have a 2 time applying rule only and after that you can't reapply. but others don't. so it depends where you are applying.
As per number 1, yes you'd be really late in the game at this point and I'm talking not even verified til october and therefore not getting secondaries til really late and therefore not even complete til most of interview season is done. Unless you are a super star applicant like my friend when she applied with a 95th percentile MCAT score from a top tier university with a high ugrad and grad GPA and extensive ECs that made her strong for the schools she chose to apply to, you will be at a disadvantage. If you have an app like hers you may still stand a shot for late interviews and acceptances.
Also keep in mind this is an EXPENSIVE COSTLY process. you will not be spending under a 1000 dollars. But probably well over such to apply to med school. As such ask yourself if it is worth it to wait another year, strengthen your app, and apply early? i'd probably do such if I were you.
