I am studying my undergraduate in medicine in Russia. I am studying at Rostov State Medical University and would be graduating the next year i.e. 2021.
So far as MBBS education in Russia is concerned, you must be careful which University you choose since there are a handful of Universities that are recommended to students from outside of Russia like National Pirogov research and medical University, Kazan State Medical University, Kazan Federal University, Altai Medical University and so on.
MBBS education is up to the mark in the Universities I mentioned above and in my own University as well. You could have been a little more specific in determining the University your friend is going to join. However, going by the date on which other questions uploaded, (2017 & 2018), I am sure your friend has already completed one two or three years by this time.
