All are relatively new schools, MUA Nevis has some graduates while AUA will have their first class graduating this May (all have done well on the USMLE). Only MUA Nevis and AUA are NY approved (neither is CA approved) while St. James is supposedly in the process of applying for NY approval. From what I've read, Antigua is a better island than Nevis. Both have strong administrations, AUA having ex-Ross administration while MUA Nevis is associated with Saba.
