How i can be perfect in English language?

LANGUAGE IS THE MEANING FULL MEDIA OF COMMUNICATION

Perfection is not / cannot be the right measure to gauge the Language skills. It is always "BEST of BEST" that can be the most measurable gauge when it comes to assessing language. To me this is applicable even for someone who has done Literate in the respective language. 

Also as far as the English dictionary continues to amend newly arrived or derived words (probably from other languages), having achieved Perfection cannot be spoken of. 

You can be perfect!

How? just simply make it part of your life.

• Put your phone and PC in English.
• Watch news in English.
• Read English news paper.
• Watch movies with English subtitle, make sure you understand each word they say and note down word you don't know to translate.
• Buy your self English grammar book (I recommend for you having English grammar by Betty Schrampfer Azar)
• Have your self English-English dictionary.(Cambridge dictionary is a real good one, it also comes with a CD for word pronunciation both US&UK)
• Watch English documentary shows.
• Practice English writing.
