CBSE class 12th board exams are the most critical exam in every student’s life. Their performance and score in the class 12th board exam determine their future career path.
For the session 2023-24, CBSE has rolled back its two-examination policy implemented during the pandemic. Instead, from this year onwards, CBSE will conduct a single examination at the end of the year covering the complete prescribed syllabus. Also, to help students acquire the skills required to meet the challenges presented by the 21st century, the board has decided to implement Competency-Based Education (CBE) in schools. Hence in the forthcoming years, more Competency-Based Questions will be asked. Competency-Based Questions examine the application of concepts in unfamiliar and real-life scenarios. Therefore, students are required to prepare diligently to ace CBSE class 12th board exams. And since effective preparation necessitates the knowledge of the exam syllabus and marking scheme, here we present an updated marking scheme, unit-wise and chapter-wise weightage of Mathematics, Physics, Chemistry, Biology and English for CBSE class 12th board exams.
According to the new assessment policy, the CBSE class 12th mathematics examination will be of 100 marks. Out of which, 20 marks are allocated to the internal assessment, and the remaining 80 marks are allocated to the theory paper. The duration of the theory paper is 3 hours (180 minutes), consisting of a mix of subjective-type questions and MCQs. Here’s the marking scheme for CBSE class 12th mathematics exam:
