@Wobblie, I agree. That was only in response to "there are no dumb students at US MD schools).
@WGSgrad, 1. Refer to above. See what I'm responding to, before you jump to defend US schools.
2. Depression, homesickness, no supervision at 18 leading to wasting away crucial years drinking and partying, not knowing how to limit themselves, any other medical condition, so you know, many many reasons why atudents may not perform well throughout 4 years.
3. The reason I said someone may not have tried in undergrad but may have on MCAT is because 1. The MCAT is usually taken at an older age (21-22). Most premed students likely have their life sorted by now. Undergrad is continuous effort and studying for 4-5 years, MCAT can be studied for in 1-2 months and if someone is smart enough, is good at sciences and critical thinking, and finally a good test taker (which all grad schools require you to be anyway, the worthy ones anyway), they can perform really well with a month/2 month prep.
Also about a 515 and low GPA but going to a DO school for med, I don't know why other students don't choose that route, but for me, I want to start practicing young (i.e. I don't want to wait and apply for multiple rounds) and I'm Canadian. Being American surely seems like winning a lottery sometimes lol.
And again as wobblie said, smarter or not, US MD students do get all the best residencies, there is nothing to argue there.
@OP, there are many past student blogs about life on the caribbean islands. A few examples:

There are many others if you look up. The girl who wrote this blog did match, but please keep in mind success at the Top 4 and especially other Caribbean schools is not commonplace. If you will be happy with the knowledge that you're serving people AND making good 6 figures ($200,000+), look into podiatry schools. Some students got in with a 488 MCAT score!!!! NUTS!!! My point is, if it is money, there are easier and more assured ways of making it. Otherwise, that blog is good but 5-6 years old, so things could only have improved lifestyle wise.
