Forget this immediatly. And to be honest I don’t really know, but, I’m gonna tell my story: so, at school we had the english courses as everyone, I come from France, a country where english skills are ultra low, so the path has started in 2015, when I was playing in online video game League of legends, I played a game, met other people from europe, they were from finland, germany, serbia etc, they invited me to vocal conversations to talk and play at same time, we all have our lame accents so i guess it was easier practice than if i would have met native english people. It was hard for me, i often didn’t understand them at all, but we were always playing together, every days in the evening we did the same routine, and I don’t know with the time I understood and talked better, I searched for more vocabulary, we even met irl, i still talk with them, it has been 6 years now since we met. So, i’ve been lucky to be able to practice in real time with foreigners through a vocal chat, but it was just my case. Some people learnt by watching movies with sub-titles, music, I don’t know. pretty good interesting story about your life.
