This is a kind of traditional teaching material for foreign language learner. Like "Essential English" published by BBC. It gives you a general idea about German and German language. Especially the illustrations represent daily life of German people.
But It is only suitable for the junior learner. For an advanced learner, it is too simple and too traditional and lack of modern feature. The best way of learning is to choose the right book and practise with native speaker.
I purchased the book on June 14,2001, and now (July 24) have finished 18/30 of the course. It is a super self-teacher or self tuition book for adults. It is especially suitable for a person like me who has a 'false' understanding of the German language. I find the auther Josephen Rosenberg knows how to lead a beginning learner into the German world little by little with interests and confidence. When you get it you will understand what I mean. This is a highly recommended book.
