Neither. I have read your post history. I admire your devotion and dedication towards medicine. It's just I don't see how it's going to work. You already went to SABA in 2011, and failed out. One of the posts mentioned that you went to the Caribbeans to save time, since you were nontraditional. It's been 5 years already.. That's a lot of time spent pursuing medicine, instead of enjoying life.
1) Reasons why you failed out of SABA most likely won't have changed. It was supposed to be a 2nd and only chance. It's gone now.
2) Even if MUA/AUA accepted you, and there is a miracle that you make it through the 4 years. Residency application is going to be tough. It's tough enough for someone with no red flags coming from the Caribbeans, but failing out of a Caribbean school... And entering another one?
Sometimes you gotta know when to call it quits.
