Just read the signs correctly. Don't worry, I have never heard about anyone who didn't find their train in a Polish railway station.
and i dont seem to get any further - lol
It's just speaking, speaking, speaking... listening, listening, listening.
And of course read some grammar, and normal Polish texts. Of course you need someone in real life who can give you feedback.
polką? = you
were a Pole? (before you died?)
(czy) ona była
polką? = Was she
(Sounds a little like the person is dead now)
Czy ona jest Polką? = Is she Polish?
