I am an intermediate student and this advanced book helped me gain confidence in myself while learning Russian. It is hard for me to memorize new vocabulary but the way it is written makes the reader understand the sentence by its simple construction. I must say I improved my Russian syntax and grammar. I certainly recommend it for other readers, especially those who already have some vocabulary and grammar roots. To sum up, after reading this book, I say with certainty that Russian is not a complicated language to learn: just go ahead!
