I trained in Normal University before, and studied the course of line testing with teachers. Later, I don't know why Teacher Shi didn't teach there. Later, I learned from other students that Mr. Shi has transferred to Goldman Sachs Education Civil Servant Training Center, and some students who studied with Mr. Shi have also transferred to Goldman Sachs. For me, it doesn't matter how famous the training institution is. What I want is a teacher who can really help me improve my academic performance.
