I started studying English by the time I was fifteen, because I had attended to another school and my teacher was requiring us a little more about that language that I wasn't good at. I got desperated, since I had come from a poor school and I didn't learn English as much as I could do. I waited for two or three weeks until realize an English course was necessary in order to get good grades and also, learn this important and cool language.
I remember that I said to my dad: if I don't take some extra English classes, I will not be able to understand classes and which it's worst, not capable to be approved in that subject. By this way, my father paid me a English course near home and my future in that subject was safed. In fact, after some simple extra classes it was crystal clear that my teacher was requiring us only ordinary concepts and I could realize I would have to study English a lot, day after day, in order to learn it as much as it's essential nowadays for who wants to compete in the workplace. Now I am studying engineering and it's certain speaking English with confidence, with a good level, is almost an obligation.
These days I've studied it by myself and I am glad with the results, you know.
