Why italki?

I created an account on italki to improve my English.

I have made a lot of progress in English over the last two years, but only in reading English.  
Now I can read books if the words aren't too difficult and I can easily understand any notice in that language.

I found that the best way to learn was to watch U.S. TV shows or series [per our discussion, you have been watching TV shows, like "Breaking Bad," and not movies] on Netflix with French subtitles initially, and now with English subtitles.

I'm enjoying it [or, "I enjoy it"].  The problem, however, is speaking, writing and understanding without any text.

I'm not confident when I need to write something, so I always use present tense and simple sentences.

I'll take an English exam in a few months to reach the B2 level of the European rank.  
The first part is an oral comprehension test where they will play two videos, three times.  After that, I'll take a comprehensive test regarding these videos.  
The second part is a writing test where I'll have to write a text about a subject.

The subject is "cultural identities through travelling."  There are three movies I'll have to watch: "Into the Wild," "Indian Palace," and "Lost in Translation."  
I'll also have to read some books about travelling.

So, I hope I'll find a good teacher who can help me reach my objectives and raise my English level.
