Actually its becoming much easier to get into med school. Like I said above medical schools such as the one in St. Kitts will take anyone with the money to fund their studies. A lot of countries are getting into it due to the high international fees I know people who go to St. Kitts, India, and other countries to get into med school then do their exams over here to become licensed.
The same thing occurs with law school where most law schools accept people with the money to get into them. A lot of jobs are becoming competitive and you really have to be in the top 10 percentile to have a good chance of being employed during and immediately after studies.
If you really want to become a doctor only a doctor can really tell you how the job is, how worthwhile it is, etc. I'd recommend talking to them because most of us aren't doctors or gone through the process and may be deterring you from what you want to do.
One thing I find good about the doctor path though is there are many alternatives you can fall back on which may be more fascinating to you such being a chemist at a pharmacy or something similar.
