Answer 1

The NCERT textbooks basically lay a foundation for a particular subject. They explain the basic and fundamentals of each topic and based on that, provide a few exercise questions to test your knowledge and understanding of the basics.

The Exemplar goes a little beyond the basic, it introduces twists in questions and has questioned a level higher than that of the normal NCERT. These are also called HOTS (Higher Order Thinking Skills) questions, which are important for many examinations.

Thank You...

Hey,

The NCERT textbook contains some questions which are unsolved, basically meant to check the clarity of concepts which are learned during studying the chapter. So, to rectify mistakes, there are NCERT Solutions which helps in clearing our concepts and analyzing our preparation level.

Also, the questions which are available in NCERT textbook are of basic understanding. So, to master the concepts up to advanced level, you need to attempt NCERT Exemplar which has some twisted problems, helps in preparation for JEE Mains, BITSAT, and many other competitive examinations.

Thank You!

Answer 4

Hello Nitish, An NCERT book will have a couple of sample problems in each topic, followed by unresolved problems at the end of each chapter. These unsolved questions are included to help you learn the concepts better and improve your problem solving ability. NCERT solutions contain step-by-step solutions to all these problems. Just think for a moment what if there were no NCERT solutions. As you can very well guess, you would have a hard time ascertaining whether your answer is correct or wrong! In case of NCERT Exemplars, they are additional material that contain practice sets with more advanced problems. The advanced nature of the problems means you can use them to prepare for competitive exams like JEE Main and JEE Advanced. Also, the complexity involved in these questions warrant that you know the topics inside out and remember all the formulas to solve them. Regards.
