That sounds closer to the American system (or was it the British?), or so I guess since I don't know exactly how it works, but it'd be cool if hanz0 mysteriously hopped in to explain it.

That also helps me make sense of this article my girlfriend sent me today (http://thechart.blogs.cnn.com/2011/0...pital-in-july/) where the writer talks about "four years of medical school under my belt, an M.D. after my name".

Here you get the M.D. after the 6 years that comprise the course, but you also start sooner since instead of the pre-med years you get the pre-clinical ones.

As for the specializations they range from 4(?) years if you're going for "General and Familiar Medicine" (which I believe is kind of the general practitioner if I wouldn't translate it literally), to 6-7(?) years for example Plastic Surgery.
Also, they start after you finish the 6 years of the course if that wasn't clear.

If you want my opinion on this system, I obviously prefer the fact that you don't have to risk 3 years doing a pre-med course, like the Biology B.S you mentioned, just to find yourself possibly rejected after that.

The pre-clinical years here have some subjects that should be somewhat similar to a Biology B.S, like Molecular and Cellular Biology, Biochemistry or Histology, but you also get right from the start subjects that are more "Medicine-specific" like Anatomy and Physiology.
I can actually post the subjects I took so far if you're extra curious.

Overall I can't say for sure how good this system is compared to others.
You've got indicators like link for the country's health system, and link for university rankings.
Take them for what they're worth.
