Today, more and more students are using the app 'zuoyebang'. However, different people have different ideas about it. Some people think it is useful because it can help students  solve the difficult questions that students can't solve. You can not only learn  knowledge at home, but also learn easily and convenitently. Moreover, you can also choose a teacher who is interesting.

However, some students pretend learning while they are using the app. Actually, they have a  chance to play games on ipads which is bad for eyes. What's more, your self-control will diminish gradually. You can't pay attention to learning. And you can't think independently because of relying on it so much.

All in all, I think it is great for the students  who are curious while it is bad for the ones who don't want to study at all.
