Depends on what you mean. You'll hear a lot of stories about Ross, AUC, and St. Georges students routinely scoring in the 230's and 240's. Sure, some do. But, my experience tells me that the majority of Caribbean students from these schools will pass on the first try and score, on average, between 190 and 210.
Having said all of that, we Carib students do need to score higher to get noticed at more competitive residencies. But, remember the U.S. average is 215. So, if you want to do FP, Peds, Psych, or other "less competitive" residencies, then you basically just need to pass the thing. OTOH, if you are gunning for Ortho or Derm, you better forego the Caribbean altogether.
