i was told that its not easy to attend the training class for free especially for those small scale class say less than 20 people in the class, as the teacher can easily know everyone. so i am going to pay for a class (could be in shanghai international study university), and i am happy to share the trainging stuff and classmates and practise with you if you feel confortable, the best way to improve oral english is to practise, practise and practise again.
