I can admit that Russian language also seemed like an UFO at first to me but after seeing that it is very structured language I motivated and learned it at advanced level. The advantage is that you pronounce almost exactly the way you write and it is very joyful to see progress, beginning to understand Tolstoy in native language is a pleasure. The New Penguin Russian Course was my main helper to learn effectively. It has the best selling Russian language book and also has the best customer rating reviews.
Real systematic, very detailed, and leaves no blind spots in your knowledge of Russian.
