the good method of English learning in your opinion

the purpose of this article is to communicate with everybody on how to study English efficiently. In fact,my first studying is in elementary school,at that time there was no concept that what English was and I even didn't know why to study English,but i am very interested in it,while other students were very bored with English,this period last two years. when i am in junior school,i was enjoying English studying,and my teacher very liked me, because i studied very well. In senior school,also I liked English but this period I found English grammar is very complex, and reading comprehesion became more and more difficult. When I studied in college , I found my English was not as good as I expected,because before college I had done a few pratices on listening, and in the second year i passed CET_4 with the score of 71,in other students' eyes i was very lucky and i had enough ability to pass CET_6, but of course after CET_4 i hadn't stopped studying English,I nearly use all time during off_hours,and in CET_6 i got 54,the second time 42,this june is the third time. Sometimes I like not only studying English but also communicating in English,but sometimes I am confused by English,do you have good method to study English, I hope you can share with me. Thanks a lot!
