NCERT EXEMPLAR In order to maintain a Uniform Education System across the country, many State Boards are implementing a Single Curriculum System via National Council of Educational Research & Training (NCERT). In the best interest of Secondary and Senior Secondary students, the Department of Education in Science & Mathematics (DESM) and NCERT have together developed Exemplar Problems in Science & Mathematics. These include practice questions of various typologies and difficulty levels which aid in in depth learning of concepts. They also contain conceptual problems which are a part of the CBSE Board Syllabus as well as the Syllabus of various Competitive Exams like IIT JEE, NEET, AIIMS, etc. Considering the diversity and the varied difficulty level of questions in these two subjects, we, at Oswaal Books have launched OSWAAL NCERT SOLUTIONS.
