Weightage of Class 9 Chapters Subject-wise

Knowing the chapter-wise weightage of the different subjects is very important for successful exam preparation. It allows students to give more time to study the chapters with more marks, hence achieving their highest possible scores. Knowledge about the weightage also helps in developing a better revision schedule and reduces exam tension by informing about which subject matter is most essential to learn. This strategy makes time management efficient and the annual exam performance better.

  • Every subject has 80 marks for the final examination, and another 20 marks for the internal assessment.
  • In Science, chapters like "Matter-Its Nature and Behaviour" and "Motion, Force & Work" have maximum weightage.
  • In Social Science, the four big units-History, Geography, Political Science, and Economics-are assigned equal weightage, but chapters such as "The French Revolution" (History), "Climate" (Geography), "Democratic Politics" (Civics), and "The Story of Village Palampur" (Economics) are given special importance.
  • For Mathematics, "Geometry" and "Algebra" have the highest chapter-wise marks assignment
