It is just as good as the previous book in the Obiettivo Grammatica 1 (A1-A2) series. It fully and clearly explains the grammar of the Italian language and contains many examples and exercises. At the end of the book, there are their solutions. As I mentioned in my review of the first book in the series, since it is written in Italian, you need to have basic knowledge of the language in order to be able to read it.
