Meritnation provides study material for ncrt syllabus . I purchased 10th class material for my brother. there are just little explanation on topic not in detail and in depth explanation . audio video animation is not updated. you can get basic knowledge from this. it will not help full for scoring good in exam. website loading time is very slow. after some days my brother is not using this. if you are looking for score good marks than you should not depend on this only, you should focus on school and regular coaching classes. price is cheap but no in depth knowledge.
