If you don't watch it, you can buy an educational ipad. But there is no keyboard, inconvenient input, no camera and no video. But it can also be external. The education version is the same as the retail version in configuration, not a refurbished machine. All teaching staff and college students, including freshmen who have been admitted but have not yet entered the school, can enjoy the preferential education version. Faculty members need to provide teacher qualification certificates, and college students need to provide admission notices and other certificates.
