Learning English

Hi, I am from Peru so I am Peruvian. 3 years ago I started to study english in an institute called ICPNA, where they teach American English. I like English but sometimes I get confused with the grammar or while listening I cannot recognize the words but when I write I can do it. This year I will start university classes so I have to leave the ICPNA because I won't have time, but I'd like to learn more and more, become part of the American people, and to speak English really well. Speaking English is one of my dreams.
