Collins Speak PolishKit - 2009
The book is split into three sections:
1. The Dialogue Zone contains 16 conversations based on everyday situations, from ordering food to feeling unwell; you can access these by reading the book or by listening to the CD.
2. The Word Zone lists all the words you're likely to need.
3. The Nuts and Bolts Zone gives you the basics of the language, such as grammatical principles and sample verbs.
The free companion website contains interactive activities linked to the Dialogue Zone of the book.
