It depends in many factors, my friend. It depends if your mother tongue is close to the English language, if you have more contact with English (through music, for instance), if you've learnt other languages (people say is easier to learn other language if you already learnt one). The lists continues... But it also depends on the amount of effort you put into it. The amount of hours you put into it. So if you want to learn English fast, first ask yourself the motives to learn it. Set a clear goal and then start to learn it. Also, some things accelerate the process of learning. Things such as traveling to an English country, talking to natives speaker and all, reading a lot, listening a lot of songs. Learning their culture. And finally, falling in love with the language and their people...

It is a long learning journey. I suggest that you study English by reading newspaper,watching English TV and reading grammar books. I tried both self study and taking lessons. I found that self study was definitely the best way to polish our English in a cost effective way.

i read articles, books, and sometimes i watch educational videos in English
