I have used this website when I was in 9 th class for learning purpose because the videos they made on the topics and the notes they provided were extremely useful. and when I came to 10 th the name of board creates a horror in my mind but by using this website material I was quite confident. the method of explaining of the topics in their videos is quite impressive and meaningful. worth my time. So if you are looking for a site which clears all your doubts and also provide the study material. You will definitely go for it. I must say that it really helps to master your concepts and help you a lot in gaining the confidence. so atlast give this site a must try. I will definitely recommend it: )
