This book was well known to me growing up. Therefore learning the Russian language, while reading a book familiar to me, made the experience enjoyable. The fact, that the audio came in both slow and normal speeds, allowed me to increase my listening skills, understanding the slower audio, than changing to normal audio. This was very helpful. It was very beneficial for me to have the PDF written text, so that I could read along with the audio. I learn better this way, reading and listening at the same time. Even though I’ve been studying the Russian language for a while, and already know many words, it was very helpful, that the PDF showed where the words were stressed, and also gave the English translation in several parts of the PDF to explain expressions and new words, that Google translate won’t always give you the correct version. I fully recommend this book to others.
