Since when could people in Russia afford to give foreigners lessons for free? I have done a programme with these people, and they were much, much better than another group I could name...And I am not a beginner, either. Previous post looks a very misguided one: if you don't have any direct experience, keep your mouth shut, otherwise you just confuse people
. I felt I was in an excellent group for my level, and worked pretty systematically through the things I needed. You get a student card as well, which qualifies you for discounts at all the museums and stuff.
