By ju’s is very very good app for learning difficult problems.i have’nt purchased book of science, then my friend’s given me idea of learning without books.Byju’s is better option option for maths also.
1.We can pause the video for clearly understand.
2.they give many examples for understud
3.we can learn by 3d method.
4.so many subjects are available.
Layout and design of this app is very good.
But this app takes minimume 3g data for play a non-stop video.I can say, It very usefull app for studing
