Really, it is? I was confused by the cover. I'll admit my German is a bit rusty (understatement of the century), but I took it as a preparation/repetition for High School or the equivalent, what with the Gymnasium reference on the box, and I wondered why anyone entering high school would need to repeat topics from the four first years of elementary school. I guess I was wrong then, and this might not be as crazy as the cover gave the impression of.
