About this syllabus
Class 12 Mathematics has six units and thirteen chapters, and one unit dominates: Calculus carries 35 of the 80 marks. The question paper design in the file adds that there is no chapter-wise weightage within a unit and that care is to be taken to cover all the chapters. So the 35 marks of Calculus may fall on any of its five chapters.
