Watching movies with subs necessarily and reading the Wikipedia in English, I make jotting 6x6 cm. with new word or expression in English and translation on the other side, and I swot it. It's very usefull.

I first learned english in school, but I have also played english games, read english book, and I like to hear english musics! It helps a lot... You can also do chatting with a friend from USA, maybe..
