I have already started two day for my PET-4 lesson.But it felt not so good.My step is learning word and expressions,then listening to the conversations,third doing exercises.Just like processing PET-3 last time.However there is seem not any progress.Also when I am doing listening test,I still not completed smoothly without catching the passages.On the other hand I am poor at oral english.Nobody can talk to me in english at ordinary time.I think I should listen and read more.Maybe it is useful.
