Hey Adi. There's multiple ways to expand your vocab, especially for English due to it being a universal language :). I think the most fun things you could do would be to watch movies that are in English, with your native language subtitles, or read books that you've read in your native language written in English. Maybe even focus on topics you are interested in. History? Videogames? Hobbies you have? Hope that helps and good luck :)
