Trial lecture means that everyone (students, teachers, office staff of training institutions) makes an appointment for trial lecture in advance, which is probably to explain one or two questions according to the child's grade, curriculum and course progress, without asking the difficulty of the questions. It is important that the knowledge points should be complete, which is generally the finale of each exam. It is characterized by easy to understand, many knowledge points and many ideas for solving problems. The trial time is indefinite (neither too short nor too long).
