Things I hated:
got sick of the food (or lack of variety) this also because I was cooking for a big family, hated my oven, doing dishes (no hotwater at kitchen sink), laundry major pain for big family, hot and humid and AC expensive (again issue for big family), hated the complete lack of customer service, expensive to travel there (no jet service/night flights), power outages, rent was not cheap (single students living together can live affordably). We did really well for about 8 months and then the homesickness settled in and we found ourselves getting really frustrated with island living. A single student will be able to afford to come home more often which helps. It is hard to adjust to a different culture while trying to figure out how to make it in med school. Dominica is NOT for everyone. Research it extensively! Even knowing what to expect you can still get annoyed at things. Some students though I swear never looked up anything about the island.
For us the biggest thing that makes us second guess our decision is the costs. We bought a car, all the plane tickets, cost of food, etc. It added up quickly and we still haven't totally recovered.
The thing I most loved was that I met some of my best friends ever. Boot camp will do that for ya!
There all other good things but I don't want to sound like an AD for Ross. I wouldn't recommend it for just anyone. Depends on so many factors...personality, how much you want to sacrifice to be a doctor, etc etc etc.
