American pre-med and medical school system / international transferring

My point is, ‘in US’. Even if I go to Korean medical school, I can’t be a doctor in America. Going to American med school lets me to be a doctor at a younger age.
Korean medical schools are competitive just like US. You have to have 397~400(full score) on KSAT to get into good medical schools. Only top students get accepted. I have worked hard and I will do the same for the rest of my life. If I wanted to be lazy, I wouldn’t even consider the med school option.
