NCERT is a conceptual book, which is written not only by a professor but by the team of subject experts. So expert team selects the concepts & problems in a very systematic manner to make every concept clear according to the standard of the student. After setting the theory and solved examples, there are the unsolved questions in the exercises given at the back of the chapters. So 9th class students suppose to solve these exercises after going through theory & solved examples taught by the teacher in the class. Professors are well acquainted with the syllabus and knowledge of the students and thus keeping this in mind the unsolved questions are designed. While solving these questions the concepts of the students are further cleared of every topic and chapter which further lays down a strong foundation for the next class. Besides this, 9th class students also start preparing for IIT-JEE from 9th class itself. They cannot prepare for IIT-JEE without going through the NCERT’s concepts. It’s just next to impossible to clear the competitive exams like ITT-JEE without solving NCERT thoroughly.
