Case Study
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 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.
