Ko? Šta? Koga? Čega? These are some questions for Serbians to learn cases at school but we try to show you -foreigners- practical ways of learning cases.  With cases, we also review some prepositions (on, in, behind, etc.). 
Hope you'll find cases easier after listening to our discussion.
Let us know your questions, comments and suggestions.

Pozdrav,
Maki i Ivana
