I don't see any reason to do pre-med in the Carib. It will be more expensive and is no better than what you will get anywhere in the US. Pre-med classes are mostly useless except to prepare for the MCAT, which is mostly useless in testing med school-relevant material. There are literally hundreds of schools in the US (maybe thousands?) where you can do all your pre-med requirements that will adequately prepare you for med school. Plus, if you do well in the States, you could have a shot at US med schools. I dunno, maybe you have specific reasons, but in general, I see few, if any, reasons to do this.
