When I came to looking for a proper app for my JEE preparation, Byju’s was a best choice. It gave me a free 15 days trial with great videos to understand my weak areas in maths and Chemistry .physics is also best but I’m not that much weak in physics. After 15 days the videos were unable to play and it seems to pay money for subscription.It is too much than what I wished.I was disappointed on the price.??
