You won't get any feedback on SDN for Caribbean aside from don't go. It isn't a route for everyone and you have to do your own research. I spent quite a bit of time trying to find as much unbiased info about all the schools and Carib in general. I ended up choosing Ross and am beginning this semester but don't be oblivious to the facts of any school. If you can, apply multiple cycles to US MD/DO and then self-reflect on whether a post-bacc or MCAT retake would make a difference. Also think about what happened in undergrad that didn't make you competitive for US schools. IF after all that, and doing your research on their real numbers behind it all you are okay with a school. then Ross or SGU are your best bets.
I personally picked Ross over SGU due to the cost being marginally better and how the pre-clinicals worked. SGU has(or had?) mandatory lectures while Ross has Panopto, though SGU just recently switched to P/F for their pre-clinicals as opposed to Ross which only has P/F the first semester then goes to a letter grade system. Most people quote the 50-56% US-IMG match rate and while it is true, these two schools are slightly better in their matches according to graduates I've talked to, and they've pegged it at 60-70%. This number is not quite true in and of itself due to the amount of people that fail/drop out, which seems to hover around 20-30% for these two schools.
Only go if you are 1). Aware of the true numbers behind it all and 2). don't plan on being a "gunner" in Carib school thinking you'll get into ortho, derm, ENT, plastics, etc. if you just work at it hard enough. If you can't see yourself in FM/IM/peds then don't go. EM, gen surg, anesthesiology, and diagnostic rads are more of the higher end that you can aim for.
TLDR: The difference between the schools are not massive and if you want to go Carib, then just pick the one you like better. Feel free to message me if you have more questions.
