What I don't understand is why not wanting to waste 2 years building up an application to apply for medical school is seen as such a bad thing. I'm planning on applying this coming cycle, and if I don't get in anywhere, I wouldn't want to spend one or two years doing boring stuff (e.g. research assistant, menial hospital volunteering) to buff up my app.
This is anectodal, but a family member of mine (Canadian), scored 27-29 on the MCAT after half-assed studying and obviously didn't get in to any Canadian medical schools despite a 3.8 gpa, so he went to SGU instead. He could've taken a year off after undergrad and retaken the MCAT in the hopes of getting in the year after, but the thought process is something like this:
What if I don't get in the next year? That would literally be a waste of a year. If you get in, great. If not, that's a year or two you won't ever get back, which to some people may not seem like such a big deal. But my cousin knew he'd probably be working some soul-sucking research assistant position, doing some research he only vaguely cared about, while attending to the PI's every beck and call. Running around groveling for hospital volunteering positions that involve patient contact, and begging physicians for shadowing positions. Basically, an extended year of pre-med life.
All those numbers about the "attrition rate" at Caribbean and "omg look how many people fail out!!!!" are definitely true (my cousin mentioned that a good portion of his class had dropped out) BUT that's doesn't really mean much if you're someone who KNOWS you can do well. If you've gotten this far, you're probably thinking like, "Well if you couldn't get into med school the traditional way, then you clearly haven't demonstrated the skills required to succeed." But I think the point most people sell short is the importance of hard work. In general, if you haven't gotten into medical school and are contemplating Caribbean, the most important things you have to ask yourself is:
1. If I work hard, will I be able to succeed? It's the unfortunate truth that some people have a limit to how much they can study and how fast they can learn. I go to a top 15 US undergrad (not super relevant, but I just don't want you guys to think I'm saying this as someone who only knows CC academics) and some of my classmates just don't understand super basic material. When I was a freshman, I knew people who straight up failed Chem 101 despite studying almost every single day. I also knew people who just barely glanced at the material and received As. I'm not saying the people who failed Chem 101 are dumb -- they just aren't good at science and math. If you were the type that literally skipped every single class, studied for exams the night before, and somehow still pulled B-/B/B+ (which are not competitive grades for med school) in competitive environments, then you will be okay in the Caribbean if and only if you work your ass off in medical school. In general, most people should have an idea of how good they are at school.
2. Am I willing to put 200-300k down as a gamble that will pay off if I work hard? In my cousin's case, his parents are rich, so money was not an issue. But he also buckled down, and really studied while he was on the island, and scored over 260 on his step 1. I visited him over the summer and he was literally studying day in and day out prepping for his step.
Honestly, Caribbean schools just accepts a lot of students for $$ -- they don't care if you've prepared yourself or are able to handle the material. The people who fail out are those that either just aren't good enough academically or weren't able to apply themselves because they didn't have enough discipline or just didn't care enough (e.g. parental factors are what lead them there). But if you are reading this and have reason to believe that you can succeed, the attrition rate doesn't matter.
What DOES matter is, if you know you want to go into some super competitive residency (e.g. Derm or something), chances are you won't be able to match, or the likelyhood is tiny. In general, it seems like for Caribbean grads to match into the same residencies as USMD's, they have to have significantly higher step scores. My cousin knows a surgery resident who is an SGU graduate and scored a ~255 on his step and is in the same residency program as a USMD grad who only scored ~230 on the step. It does seem like an uphill battle -- you basically have to outperform USMDs to get the same position. But maybe it's worth it if you don't want to spend the extra couple years doing menial premed labor, aren't interested in super competitive residencies, and have the money and self-ambition to take the risk.
Having said all this, I don't know much about the MD-DO merger or how that will affect matching rates. I just typed this because it did kind of seem like OP was getting attacked. He was probably just feeling like all the anti-Caribbean hate was invalidating his hard work, which is never a good feeling.
Last thing, my cousin is in his rotations (M3), and I've never heard him mention anything about the "goodie bags" that someone brought up earlier in this thread. He also seems to be on call at least every other week. This is anecdotal evidence, so maybe other Caribbean MD students are being given goodie bags, but it's important to note that whoever observed the goodie bags being given out was also giving his anecdotal experience.
