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 and Training (NCERT). In the best interest of Secondary and Senior Secondary students, the Department of Education in Science and Mathematics (DESM) and NCERT have together developed Exemplar Problems in Science and Mathematics. They also contain conceptual problems which are a part of the CBSE Board Syllabus. Considering the diversity and the varied difficulty level of questions in these two subjects, we, at Oswaal Books have launched OSWAAL NCERT SOLUTIONS in a Chapter-wise and Topic-wise format along with their complete solutions. We believe that OSWAAL NCERT SOLUTIONS will help the students in school and after school in practicing and preparing extensively for both, Final Examinations with utmost confidence!
