It assumes no prior knowledge of Irish, with each lesson building on the previous one.
Great effort is made to fully explain the grammar, and to provide help with pronunciation.
The dialect used is from the Cois Fhairrge area west of Galway. Each chapter includes new text, often in the form of a story, related grammar, and exercises. The recorded material follows the text of the book and, although sold separately, the book and cassettes must really be used together for the best results. This is an excellent course for people who really want to learn and understand the language. There are two volumes to this course, each sold separately and each consisting of a textbook and 3 cassettes.
