Hello, Jiangsu joined the unified examination of teacher qualification certificate. After the unified examination, the interview materials are not fixed. However, the national examination interview uses multiple-choice questions, and most examiners are local teachers. Therefore, the textbooks that can be used for the general teacher qualification examination should be local textbooks. Middle schools are generally dominated by senior two, but it doesn't mean that other grades don't take the exam. What matters is not the content, but the teaching method. After mastering the teaching methods, any topic can be taught well.
