When it comes to learning and gaining marks, every student do ample things. I am also one of them. We try the possible methods to remain on top of mountain and to solve this purpose I took byju, but it didn't work for me. The prime reason for calling it bad is absence of our mother tongue Hindi in it. No matter how we get sophisticated but we will always remain Indians and can learn in our mother tongue best. Then second thing it worsely affects the eyesight of the child. See the fact is we all are humans and think in pictures but we cannot learn and picturise at the same point of time especially children who do not have such a developed brain as adults have. So to cope up with this is quiet difficult for them. I know the allegations are from the sides of working parents who do not have much time to spend on their children but I want to tell all of you that please at least take out half an hour and talk to your children about their studies and other things which in fact help in developing of child. At last I want to say that don't just waste up your money and child's time in such app and try to communicate with them because your money can be recovered but child's time cannot.
All the best all of you. Stay blessed and happy and I hope a good future for all of you
