1, cost-effective. Each subject of ape tutoring is divided into three levels of difficulty, step by step, and the overall design of the content inside is like a child's daily game, but a book has no such experience. There is a book mainly about the counseling of basic problems, which is not perfect compared with the knowledge involved in ape counseling.

2. Good reputation. The auxiliary teaching materials of ape counseling are very easy to use, which have won unanimous praise from ape Bao and parents, and are full of learning ceremony. A tutorial material belonging to a minority has not been liked by many parents.
