The most difficult part of learning English (and a foreign language in general)
is that there is a big gap between formal and informal language. I downloaded an
app to talk with people from different backgrounds and cultures, and there it is
easy for me to understand and be understood.Then, when I wrote an
assignment at university, my professor told me that I'd made many mistakes with
vocabulary, structure and grammar. The problem is that I'm attending a master's
degree in languages and communication and my level should be a C1, but I think
that I am still a B2 learner and therefore I have some trouble. Moreover, it is
hard to overcome my lack of confidence when I talk with others, especially when I
know that I will be judged.
That was very well written.
