This must be the majority students doubt. How to learn english?There is no secret. In my view and experience as an English teacher, there isn't a magic ( doesn't exist a magical pill, " since today ur gonna speaking english"). Students have to study harder to achive their goal. Have a look bellow, I did a small list with some tips that might help to improve the language quickly.
1- reading, as much as you can
2- starting listening , music, news, magazines, movies, everything you find out in english
3-study at least one hour per day
4- correct your grammar mistakes with a friend
5- get in touch with native english speakers through the internet
6- repeat the new phrasals loud, then u brain can memorize it.
7- trying to write a couple of new words everyday, and use them in a text
