I didnt apply to 1 US school because I knew I didnt have the credentials and if I just wanted to burn money id throw it in the woodstove or something. If you really dont think you can get into the US schools, and dont want to do osteopathy (which was my case too), apply to SGU or whichever other school you are considering. Just make sure you look at the schools stats and make sure they can land you (and more importantly you are capable) of where you want to be. I go to SGU and its a great school in my opinion. You could always do a post bacc program before applying to carribean schools, as I wanted to do, but changed my mind after coming the realize its just more time and $, and you have to do superbly to be considered for admission. Slim chance, but you could come to a carribean school and transfer out after taking step 1. So thats about all the possibilities I see but I'm sure others here can add to the list.
