1) If you ask about the med program in English, they dont have CMB approval, but if you ask about native language program, both have :
Welcome to the Medical Board of California - Medical Schools Recognized by the Medical Board of California
2) Do they have NBME exams really? Its supposed to establish US system of teaching and to prepare you for USMLE exams. None of the schools in this region are in full compliance with US system, but to have exams in NBME format is a good indicator. Even if you dont feel satisfied with the tests you will find in the school, you can directly purchase from NBME your own trial exams as many as you like for self assessment for little fees
PS: The one that has CMB approval
AND provides a quality education
AND a future in US for
most of its grads is Jagiellonian.
(Most = the serious students, not the partying ones).
