My child is in the second day of junior high school, so we should audition before signing up. At that time, after the free audition of mathematics, the teacher gave a very detailed subject diagnosis report and follow-up study plan. The child said that he liked this teaching method and the teacher taught it well, so he signed up. Both computer and PAD can attend classes, and there is no need to download or install anything. You can have classes if you have the internet. After studying for a summer vacation, the teacher helped to make up for the mistakes. Now, when I start school, I listen to my children's feedback and say that I feel that math learning is much easier. I hope I can help you and adopt it.
