The Central Board of Secondary Education (CBSE) has announced a major change in the answer book structure for the Class 10 Board Examinations 2026, specifically for Science and Social Science subjects. Students will now be required to write answers strictly within subject-wise designated sections, ensuring streamlined evaluation and reducing discrepancies in marking.
The new format divides answer books into clear, subject-specific sections. CBSE has instructed all schools to train students thoroughly on the revised structure during pre-board and school-level assessments.
NEW SECTION-WISE ANSWER BOOK STRUCTURE
Science (Class 10)
Students must write answers in the following three sections:
- Section A – Biology
- Section B – Chemistry
- Section C – Physics
Social Science (Class 10)
Answers must be written in four clearly marked sections:
- Section A – History
- Section B – Geography
- Section C – Political Science
- Section D – Economics
Each section has a dedicated space, and answers must not be mixed under any circumstances.
Strict Evaluation Rules
CBSE has clarified that:
- Any answer written outside the designated section will NOT be evaluated.
- If a student writes answers mixed across sections, the response will not be checked.
- These rules apply during:
- Board exam evaluation
- Verification
- Revaluation of answer sheets
Schools are directed to ensure that students get ample practice so they do not make structural mistakes during the final board exams.
Why Did CBSE Change the Format?
Until now, Class 10 Science and Social Science papers followed a format of 5–6 mixed sections (A to E/F) containing:
- MCQs
- Competency-based questions
- Short & long answers
- Case-based questions
- Map skills
Questions were not divided by subject areas like Physics, Chemistry, Biology, or by Social Science units.
The new structure ensures:
- Clarity in evaluation
- Reduced checking errors
- Better subject-wise performance assessment
