firstly, you have to get rid of the fear and speak in English at every opportunity. When you learn to swim, you just jump in the water, it's the same with English, just "jump"

one of the best and easiest way to learn English quickly is to watch movies without the subtitle . plus try to use and practice every word you have learned with your friends ,and it would be better if he/she is an English native speaker . good luck >> cheeeers

I think the best way for learning English is to watch english videos and listen native speakers, and very useful is to try to have conversation in english.
