Where the marks are
CBSE publishes marks by unit, not by chapter. The Geometry unit carries 15 of the 80 marks in the paper, across 3 chapters. Our estimate for this chapter alone is about 4 marks — useful for deciding what to study first, but it is our split of the unit, not an official CBSE per-chapter figure.
