I think the best thing for you to do is to listen to television shows or even variety shows. Listening in the number one key to learning english. Also, see if you can find someone to speak to in english. practice makes perfect. When i learn a new language, i put post it notes on objects and write how to say it in the language im learning. It makes it easier to remember and you are exposed to it every day

You should try watching tv in English with subtitles first, meet people who speaks English and listen to music in English. That's how I improved my English

Learn the basics, listen to podcasts/music, watch movies, skype with tutors/friends etc...
