I know that there are some IMED listed universities in Ukraine and is it a good idea to study there for a person who wants to become a MBBS doctor? If you provide some articles with detailed info on the topic, I'd be glad. I've just started my research so at this point I don't know much and any help will be appreciated.

Here is a website that will cover all your questions I think - http://leader-education.com/story-of-success/ . And I think that mbbs in Ukraine is really a good option for those ones who chose this career path.
