Li Jiang

When I was in the primary school, I often met with problems which I could not work out on my own, especially in English and arithmetic. So I downloaded an online educational app named Zuoyebang. Since then, I have been using several kinds of such software, for example, Xuebajun and Haofenshu. Whenever I have a problem, I will turn to them. As a result, my study has been progressing steadily. I will strongly recommend these apps to my friends.

Su Hua

After entering the senior high, I found I had more and more difficulty learning maths and English. As many online learning products are quite popular among other students, my parents subscribed to one for me too. After that, however, I feel as if I were going to two schools, one real-world school and one online school. Every day I have endless exercises to do and feel very tired. Worse still, I feel I have lost interest in my study now. What shall I do?
