NoAgenda's advice is good.

Use it as much as possible! Surf the internet in English. Chat as much as possible. Wright a diary in English.

That depends whether you want to learn fast or slow, if fast then join an English institute, but if you are not in a hurry then you can watch movies, listen to songs, and of course go to the tourist places and meet foreigners there to practice speaking

you should read books and watch film. reading books is for learning words and watching film is for pronunciation. You should do practice with native speakers too...

Films and musics brings you a good ready sentences and expressions to use in your conversations English friends to discuss and practicing .. ^_^
