You do get a lot of hands on experience your first year. In our anatomy class we have a large and small animal palpation component where we are working with live animals, feeling structures, learning how to do a physical exam, auscultation, etc.
The first SEMESTER you live on campus, not the first year! Keep in mind that we have 3 semesters per year, so you'd only be living in the dorms for 4 months or so. You cannot live in the dorms past your 1st year. As far as if living on St. Kitts is hard, that will vary from individual to individual. There are some people here who do nothing but complain since the moment they step foot off the plane. Myself, I kind of love it here. It is a lot different than living in the states, though, so how you'll react is dependent on how adaptable you are.
I live in Monkey Hill/Cedar Grove right now and I find it to be very safe. My next door neighbor is a former police officer and the house across and to the left of me are both families with young children. Bird Rock also appears to be very safe. I heard a lot about how "safe" Frigate Bay was before I moved down here, but: A.) It's ridiculously expensive. Like $800+ US/month for a 1 bedroom. B.) The most break-ins since I've moved down here have all been in Frigate Bay, including two into faculty homes.
As far as crime goes, 99% of it is petty theft. Laptops, cash, etc. stolen while students are away during the day or over break. There is some violent crime, but honestly, your chances of being assaulted with a weapon down here aren't any greater than back home. Lock your doors, make sure you get a place that has been approved by off-campus housing with security bars on the door and windows, and you will be fine.
