CBSE Releases Subject-Wise Marks Bifurcation for Class 10 and 12 Board Exams 2027

The Central Board of Secondary Education (CBSE) has officially released the subject-wise marks bifurcation for the upcoming 2026-27 academic session. This comprehensive update provides students, teachers, and parents with a clear breakdown of how marks will be allocated across theory examinations, practical assessments, project work, and internal evaluations for both Class 10 and Class 12 board examinations.

The notification serves as a critical guide for students preparing for the 2027 board cycle, offering transparency regarding the structure of their assessments. By reviewing these details, candidates can better understand the weightage assigned to different components of their curriculum, which is essential for effective exam preparation and time management.

Breakdown of Marks and Exam Structure

For Class 10 students, the board has outlined the distribution for a wide range of subjects. In many core subjects, such as Science, Social Science, Mathematics (Standard and Basic), and English Language and Literature, the total marks are set at 100. This is typically divided into an 80-mark theory examination and a 20-mark internal assessment component. The theory papers for these subjects are generally scheduled for a three-hour duration.

The structure varies for skill-based and vocational subjects. For example, Home Science is assessed with 70 marks for theory and 30 marks for practicals. Meanwhile, subjects like Computer Applications, Information Technology, Artificial Intelligence, and Data Science follow a 50:50 distribution, with 50 marks allocated to theory and 50 to practical examinations. These specific subjects often feature a two-hour theory examination duration.

Class 12 Assessment Patterns

The CBSE has also provided detailed bifurcation for Class 12 subjects. Science stream subjects, including Physics, Chemistry, Biology, and Computer Science, are structured with 70 marks for the theory examination and 30 marks for practical assessments. In contrast, humanities and commerce subjects such as History, Political Science, Economics, Business Studies, and Accountancy are generally divided into 80 marks for theory and 20 marks for project work or internal assessment.

Vocational subjects in Class 12 also show varied distribution patterns. Subjects such as Retail, Web Application, and Informatics Technology are assessed with 60 marks for theory and 40 marks for practicals. Multimedia courses are split evenly, with 50 marks for theory and 50 for practical work. The official documentation also clarifies requirements regarding external practical examiners and the availability of practical answer books for these subjects.

Students are encouraged to consult the official CBSE notification to verify the specific marks distribution for their chosen subjects. Understanding these requirements early in the academic year is recommended to ensure full awareness of the assessment criteria for the 2027 board examinations.
