Ah, so popular PMs and posts after a few hrs of joining
I am from Chicago, on the 3rd year of 6th.
Actually I found out from my parents as they finished here as well (but the Polish side many many years ago)

Honestly, I love it. I had my doubts in the beginning, well being so far away from home, friends, family. But honestly, the first year you'll make plenty of new friends from around the world and you won't really have time to worry about home a lot of reading
Studies are not easy. All the questions we get on our tests (MCQ but they arn't easy) are USMLE style. They do prepare you well for the USMLEs (well haven't taken mine yet, but I do study from Step 1 for the tests here soo...)
Class wise currently I believe Ithere are 54 of us (or 53, can't remember). First year anatomy we were 10 per professor. Other classes as small as 3. In Peds now there are 3 of us per doctor. Internal medicine groups of 2. You really don't get that 1 on 1 in the USA or Canada.
The university is very old with a lot of history, but then again they do have many new buildings. There are many computer labs, student study rooms with wifi, etc.
There are always cons to everything, but for me the only thing is as a foreign medical graduate I need to do better on my USMLE than USA students to get accepted into residency in the USA.
GPA I am not sure what is needed, but I had a A- average with 6 years of science in HS with AP courses and 1 year of night college science, and a 33 on my ACT.
Admission is also now based on a entrance exam. We didn't have to take that. But don't get discouraged! They do look into any extra curricular activities, and how "well rounded" you are in other fields. It never hurts to apply!
But overall
Very small classes and great student to professor ratio
Saving 2 years of study
No MCAT to take (for the 6 year)
All in English
and 1/4 the cost of a USA med school are all pros
