I am using this app and whatever my experience is, I want to share it. First when I downloaded the app I was very happy that I can learn everything through videos but for only 24 hours . They have given free access of all videos for one day after that they ask you to buy their course by paying ans gave only one video free from each topic . So it is good for learning for rich students not for poor. But if I talk about the service it is very good and students can understand the concepts through videos and learn something in real manner . Hope so this review will be helpful to you.
THANK YOU
