Note:
• Subject teachers are advised to direct the students to prepare notebook of
the Terminology/Definitional Words used in the chapters for enhancement
of vocabulary for clarity of the concept.
• The NCERT textbooks present information in boxes across the book. These
help students to get conceptual clarity. However, the information in these
boxes would not be assessed in the year-end examination.
