Where is it, or where am I going
Ten minutes putting the где?/куда? split to work: build three sentences that give Београд and центар the ending their question actually demands - staying versus going - then correct the mistake every beginner makes leaving the location -у ending off a place you're merely visiting, before the unit's own walking tour asks you to track both at speed.

У and на - location versus motion
Both у (in/at) and на (on/at) have two different endings depending on the question they answer. For location (где? - where?), masculine and neuter nouns take a fixed -у ending, the same pattern days-months-a1 used for months: у Београду (in Belgrade), на столу (on the table). Feminine -а nouns take -и instead: кућа → у кући (at home).
For motion toward a destination (куда? - to where?), the noun instead takes the accusative pattern from cases-introduction-a1: masculine and neuter nouns stay unchanged, feminine -а nouns become -у. Идем у Београд. (I'm going to Belgrade) leaves Београд unchanged; Идем на плажу. (I'm going to the beach) changes плажа to плажу.
