First, let me ask you What do you think about English ? Is it really important for you? If you say yes, let me share you a little experience . Now, let's start
If you want to good at English you must get up early in the morning, at about 5:30. In the classrooms at school, you can not talk in the lesson and focus at the teacher . You can try do your homework in the class. After school, you ought to at home and learn English. Sometimes you can go outsides and play with your friends. At night, you should save up 30-40 minutes to learn English or you can listen to the English music songs
AND THAT IS MY EXPERIENCE. GOOD LUCK AT YOU
