Can anyone recommend any self-study books for Level B1 in Polish. I have been using the "Cześć, Jak się masz?" for levels A1 and A2, and found these books really good. But the next title for Level B1 is simply not intuitive to me at all. i.e. It seems to just repeat the grammar from the previous two books, whilst giving you thousands of words to learn without any context to relate them to. The book is almost certainly designed to be used with a tutor, as are the Hurrah Po Polsku books (Which I also own).
Polish in 4 weeks level 2 is designed for B1. It's a pretty good book.
However, you need to revise the A-level grammar. Polish in 4 weeks Level 1 is probably the best Polish course book I have seen.
Also try to read Polish online newspapers. It's free, and it's one of the best ways to get a better vocabulary on this level.
