Complete Russian Beginner to Intermediate Course: (Book and audio support)

I've been using this book simultaneously with the Duolingo russian course to learn the Russian all by myself (self-learn) and I'm boosting through the language course. This book has dialogues, cultural exposure and tips throughout - there are 20 chapters and I take it with me even if I'm travelling and I'm almost through with the entire book and am pretty happy with it. Definitely recommend but only if you feel you can commit to a self-learn book, as some people would probably be better off with classes in school or uni.
