I bought the kindle version of the book and then I bought the Audio CD to complement the book. There are no match whatsoever between the book and the CD.They are only very few lessons and exercises that do match. It is however a painful experience .This fact is not advertised anywhere. I consider this a big mistake and a misleading offer.That is why Iam not giving any star to this item (I am forced by the system to show a rating, so I am giving one star).I feel strongly about this and Amazon should proceed to correct the way these items are presented. If you want to have a good head start at Norwegian I do recommend thePimsleur Method. You can learn more about the product in [ ... ] (a Division of Amazon).I purchased/downloaded the complete course of 30 lessons.IT's GOOD STUFF
