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 or clarity of concepts.
• 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.
