No pain no gain

I thing that each student that start to learn English here in brazil on day made this question to himself. How many hours are necessary for on student to learn English?
I think that this number depend of the situation, relative with the interest and the technician used to study.
However how many hours the specialist consider necessary to learn English with fluency? I decide to made a search in the internet and discovery this number.
Anybody can learn English in one thousand and two hundred hours of study. This number is real and don’t depend of a big intelligence, we can reach this purpose studied this number of hours with discipline and dedication.
If you studied in a regular school three hours for week only, whiteout study hard in your home, you expended 8 year to learn, however if you studied two hours for day you less this number for two year.
In this case don’t exist miracle you have to work hard, study a lot.
You can improve your English rise the exposition with the language, read bookes, magazines, listen music, radio see videos, talk with other, you need to dedicate one hundred percent to obtain a result. Whiteout pain we don’t have gain.
