According to things I heard from his parents, Amir-saum didn't experience a very good time with his previous teachers. But he didn't give up. Apparently his former violin teachers had been totally ignorant about teaching knowledge as I heard from Amir-saum and his parents about them. But nowadays he responds excellently to his violin class with me and does his job very well. In coming future he is going to be one of my best students. His father can play guitar a little bit. He accompanies his son and helps him with his daily rehearsal.
