My brother got accepted in UCC in Bayamon,Puerto Rico after his junior year. He is graduating this year, so it went really well for him. The concerns that you should have is, are you sure that you want to go to med school, and do you think that you'll do good.
I know of people that studied with him and dropped out in their last year (yep, they did). Imagine if you suddenly feel like it's not going great for you and you're not doing as well and you don't have a Bachelor's degree as a backup plan. It really is something to think about carefully.
P.S. Schools in the Caribbean are good... In puerto Rico, specifically UPR and UCC
