Do you have any more courses in the pipeline for level B1 Polish? It is quite a big jump from B1 to B2 in the Podcasts and, as a 'mature' student who loves classical music and opera, I do not enjoy pop songs, though I appreciate it's a helpful way of learning a language for those who do. One suggestion for you - Is it possible for you to include exercises that require composing a sentence rather than simply remembering the basic form of words?
