Translation of Fehlbesetzung in German-English

Ok. I will send you a new exercise. As far as I remember, you got the book for 10 Euro. Is that correct? Meanwhile, please send me your email address, your Skype user name and if you want phone number.
After that I expect that you do the same. Write me a text in English and the same translated to Spanish. This way we will learn all directions. We will be able to compare the texts and learn.
Let me understand further: If you go through the 'vocabulary builder' in the left menu and choose new lesson it works faster than when you get there through the list of all lessons? Did I get this right?
