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?
When I was preparing for the IELTS exam, my tutor told me that I needed to speak and think in English. It was easy at home because my wife and I had to take the same exam. We talked in English for quite a while, and whenever we needed a word, we hit the books, even during the fights.
Now to the “thinking in English” part. We were encouraged to have our inner monologues in English. Everything we thought about should be in English. If we had a problem with that, we should go to the dictionary.
Last but not least was the exposure to the “media”. All the movies we watched were subtitled at first, and eventually we watched movies without subtitles, often rewinding the difficult parts. Same with music.
Nowadays, the so-called AI assistants help with the correct gamma and spelling. But I still use an analog dictionary when in doubt.
