Is the textbook of vipjr easy to use? Have you ever experienced it?
In order to better adapt to domestic teaching, the Oxford textbook used by vipjr has been specially modified to achieve full coverage of exam-oriented education knowledge points, so it can quickly improve children's academic performance. My son has studied for three months and found nothing wrong with the textbook. The biggest change for his children is to see that foreigners are no longer shy, that is, to see the market.
