What do you think about making a video with polish tongue twisters, or maybe your polish is good enough to make a whole video? It could be very funny! Also, i've been watching you for a while and i think i remember you when you were working as a teacher in Radom.
It's a great question. There are loads and loads of rules surrounding prepositions. The problem is, is that there are more exceptions than rules so it is best to learn them in chunks
