Can anybody tell me how tough the competition is for U.S citizens who want to go to medicals school in Canada? Especially for someone like me who actually took some science courses in college. I did not do well in them but ended up going back to school after I received my undergraduate degree. My grades were far better than what they were 3 years ago. However those grades are from non science courses. Can the improvement in grades help with the admission process for some Canadian schools?
