Where the marks are
CBSE publishes marks by unit, not by chapter. The World of Living unit carries 27 of the 80 marks in the paper, across 4 chapters. Our estimate for this chapter alone is about 7 marks — useful for deciding what to study first, but it is our split of the unit, not an official CBSE per-chapter figure.
This chapter is not on the board yet.
We author chapters one at a time and only publish once the lesson has been checked end to end, so we would rather say "not yet" than ship a thin one. The syllabus above is accurate and free to use meanwhile.
