Hey there,
I have answered this question before but I am copying and pasting a past response because I feel that it is important that you understand what you are getting into before committing to these programs:
I was accepted to the Medical Scholars Program at UMiami. I am currently entering my 3rd and last yr at the U of Miami. I took the MCAT this past weekend hopefully for the 1st and last time. The requirements for the program according to its website are to have a 3.7 gpa both science and non science and a 26 MCAT. However since I started college before the requirements changed I need just a 3.2 science gpa, 3.4 overall gpa and I was told that I don't need a minimum score on the MCAT-just need to take it.
I applied out of HS to UM's BS/MD programs for HS seniors and didn't get in. My only advice is to make sure you understand what you are getting into when you apply to these programs. Some people, like myself, should experience college before deciding on med school. Sure I wanted to be a doctor in HS but my experiences in surgical rooms, doctors' offices, and research further fueled my decision to study medicine. I now feel more ready and sure of myself as I embark on my future medical studies.
So if you feel ready and sure that medicine is for you then by all means apply now. Just realize that these programs are not for everyone and that you are making a career altering decision so soon.
Good luck!
