Thanks for your respond))) I really have problem using the preposiitons with the right cases and genders. The think making the learning harder is the fact that Russian nouns' genders are not the same as german one's. i.e. the girl in German is Neutrum. I also have problems choosing the right Kursbuch. I wish someome experienced could help me with the choice of a book. there are so manz of them, like Schritte Int., Temen Neu Aktuell and so on.
