Well, in these months I've learned a lot, many stuff that I didn't know or I knew but I applied incorrectly. Hence, my knowledge has increased too much. 

I consider this is the most important and helpful course that I have taken, since as everyone knows grammar is the basis in any language. So my experience have been amazing I'm too satisfied with the results of both the knowledge acquired and learning. I hope to learn more, and besides apply all of these piece of advice in order to improve my language skills every day more.
