I finished my Duolingo skill tree!
Now, my route is somewhat different. I've discovered a really great website called Lingvist, to continue learning my French. I'm actively and extensively using it for a few days until now. It is really addictive for me, because I've gained a thrust in the system.
I've concluded that I, at the very least, have some base in French, and now, which is a great discovery for me, it has helped me in broadening my vocabulary in English, too! :)
I also plan to try out (in the moment of writing this) the website called ReadLang, in which I will mostly import texts which are from the other sources which I have, and from what I find later.
I am also writing the words and phrases which I will paste to some kind of SRS (I haven't figured out which one to use yet)
Because it is really important to understand before you speak, to achieve that, one needs to listen a lot. Now, I won't dwell on how you should listen, on understanding of the spoken language to which you listen to, but I think that, what was missing from my learning is trying to really understand what's going on in listening, and to listen to other things except the series Plus Belle La Vie. I will say that it is also important to have a transcript of the audio, if possible. Therefore, I will focus on, primarily, the things like podcasts with transcript, videos etc.
I also want to mention that I've finally found the language partner, on Language Exchange. Soon, I will be speaking with her. :)
