CBSE Class 12 Maths Exam 2026 is scheduled to be conducted on 09 March 2026 (Monday). Mathematics plays a crucial role in determining overall board results, especially for science and commerce students. Over the years, CBSE has consistently framed questions directly or indirectly from NCERT textbooks, including solved examples, exercise questions, and miscellaneous problems. Identifying the most repeated NCERT questions chapter-wise helps students focus on high-weightage areas, strengthen conceptual clarity, and manage exam time efficiently. This article provides a detailed chapter-wise compilation of frequently asked NCERT-based questions for effective and targeted revision.
