The Council for the Indian School Certificate Examinations (CISCE) has published the new ISC Class 12 Mathematics Syllabus for the academic year 2025–26. The syllabus comprises of two papers: Paper I (Theory) (80 marks); and Paper II (Project Work) (20 marks). The theory paper has three sections: A - compulsory; B or C - students will make a choice between B or C. The clear course syllabus enables students to appropriately align their preparation to their exam.
