Now I can watch some films with subtitles, read texts(I think my level is about A2 - B1) and understand the main point, but I feel like I need somehow to expand my vocabulary. I tried to learn new words using flash cards and it’s seems effectively. But too boring for me and I just can’t do it. So, maybe you can give a couple recommendations?
As the other commenter said, speaking to people who speak the language is one of the best ways to learn a language.
