While NCERT textbooks cover fundamental concepts, NCERT Exemplar Books provides students with challenging practice problems beyond the standard NCERT textbooks. These questions deepen the understanding of concepts, develop critical thinking skills, and prepare for more complex application-level questions asked in competitive exams. Besides this, for in-depth learning, solutions are needed. To fulfil this need, the revised edition of NCERT Exemplar Problems-Solutions Science 9th is designed as per the latest rationalized NCERT. Chapters offer precise and detailed solutions to all the questions in the NCERT Exemplar Science textbook. The questions that are removed from NCERT but important for competitive exams are added at the end of each book. With new features like Thinking Process, Concept Insight, Alternate Method, and Mistake Alert, the series brings solutions to problems of higher aptitude.
