On the other hand, the requirements of the anxious mom of my student is unreasonable. I was asked to enhance the audio performance of her dyslexic son within an hour. I can't really do it. But anyway I came there, found that the kid is still as lazy as before. He did got better audio memory on vocabulary. He can do better in recognizing the vocabulary by listening to them instead of reading them on paper. I think it's a good way to train him.
I haven't made any contact with them.
