Iago

Highly recommended. I have a massive weak point in Russian when it comes to grammar, however, after roughly 6-7 lessons with Anna I can already notice a real improvement for I find myself being able to tell which cases to use in a wide variety of situations. Even if you are fond of self-education like I was, it is really worth a shot since there is only so much you can learn on your own and having a competent teacher makes a huge difference.
