Learning English just like learning any other language, is hard work so my first advice is to spend much time practicing using English every day. Besides, we should listen to the teacher and take notes carefully in class. Go over what is learnt regularly and finish doing our homework carefully. Listen to English radio programmes, read English stories and newspapers, watch English films and TV programmes ,keep a diary in English and attend English debbates and speech contests. If we make mistakes, correct them at once and try not to make the same mistakes.
