NCERT EXEMPLAR PROBLEMS
NCERT has developed some excellent problems called ‘Exemplar Problems’ in Science and Mathematics for secondary and higher secondary levels. These problems are not meant to serve merely as a question bank for examinations but are primarily meant to improve the quality of teaching and learning in schools. Students can benefit themselves by attempting the exercises given in the book for self-assessment and also in mastering the basic techniques of problem solving.
Thus, in order to score optimum marks in the board papers, it is very important for the students to practice a variety of questions. In addition to these exercise questions, it’s also important to practise the NCERT Exemplar problems.
NCERT Exemplars are basically practice-books that are designed to assist students to increase their understanding of particular skills, content or knowledge in any given situation. They include extra questions of a higher level that are very useful for conceptual understanding and strengthening your problem solving concepts. These books contain conceptual sums, which cover CBSE board and competitive exams like JEE main, JEE advanced and other Engineering Entrance exams.
