I've got almost 100 crowns in Polish. I know a lot of words, but my listening and reading comprehension is still poor. Is Duolingo working on stories for Polish learners?
You should be patient, Duolingo won't do the whole job for you!
There are a lot of sources on our forum for Polish learners. I think we all can help to each other.
I recommend to you this site to start talking Polish. https://www.italki.com/i/DbDBEE?hl=en_us It's free and very effective. You can find a partner for talking. It is very easy for English speakers, because English is very popular.
