Our child's physics teacher is called Zhang Sentong. He has seven years of teaching experience and spent five years in senior three. He speaks physics very well. Physics was originally a arresting course. Our children have changed several makeup agencies, and nothing has improved. But since learning from teacher Zhang, the foundation has been consolidated bit by bit. He also knows how to use knowledge flexibly, integrate theory with practice, and especially likes to do it. At home, he also studies hands-on experiments and actively calculates. Now my child has been successfully admitted to the Polytechnic University, and I am very grateful to Teacher Zhang.
