ISC 12th Mathematics Marks Distribution 2026 Chapter-Wise

The ISC 12th Mathematics Marks Distribution 2026 blueprint shows which units and chapters have high weightage. The chapter-wise marks distribution for the theory segment is an estimate based on the previous year’s trend.

ISC 12th Mathematics Marks Distribution 2026 Chapter-Wise: The Indian School Certificate Examinations (CISCE) will conduct the ISC 12th Mathematics 2026 exam on March 9, 2026. Here, the candidates can find out the ISC Class 12 chapter-wise marks distribution and the most difficult topics. As per the analysis, Calculus is the most weighted chapter, from which the candidates will get 32 marked questions. Candidates should practice the high-weightage topics more so that they can score well in the exam.
