Query: A bit disappointed...

For the cost of this book, I expected more. My hope was that it would help me refine my understanding and use of Russian script. It contained about two pages of script exposition, nothing more than anyother teach-yourself type course does. If you are completely illiterate in the language, you may get some benefit from this book, but if you can read even a little Russian already, you're too advanced for the scope of this material.
