Meritnation is a website that helps students in solving their homework problems and helps with a better understanding of the concept by numerous videos which explain the concept very nicely. I used it from my 8th standard to 10th standard and then I did not see any use in that as I choose state board over CBSE.
But during the period of use, My experience of the website was very good probably and the layout and the content is also good.
BUT, How can you give the solutions to the problems without even letting the students try? I would not recommend that. That hinders the learning capability of a student.
