English biography

I've studied English since I was six years old. But now I studied English in a public school of I was fourteen years old.
In the next year of secondary school I didn't know or didn'r understand anything because I didn't understand the vocabulary , grammar, etc. Then I  started studying in lenguage school, "salt idiomes".
I haven't spoken English in my home. Because my parents can't speak English. But my mother has got a cousin who lives in Scotland. She speaks English.
I want to learn English because I want to travel to New York, London, New Orleans,etc.
