Query: A very useful book

I use the Berlitz Basic Italian Workbook in my advanced Italian class. It contains varied and entertaining exercises that provide practice in grammar while preparing the students for different everyday situations. There are a few mistakes in the book but they are insignificant. The book has another advantage: it is affordable. There is no point choosing a textbook that the students can't afford to buy!
