Section 3: Major Changes in the CBSE Class 12 Syllabus 2025-26
Detailed overview of subject-wise syllabus updates, additions, and structural changes
The CBSE Class 12 Syllabus for the academic year 2025-26 has been updated in alignment with the National Education Policy (NEP) 2020. While the core structure of most subjects remains intact, there are subtle but significant changes in syllabus content, assessment weightage, and question formats.
This section highlights the changes that will impact students across Science, Commerce, and Humanities streams.
1. Syllabus Rationalisation Continues
CBSE has retained the rationalised syllabus approach initiated in the post-pandemic phase. Around 30% of the older syllabus (pre-2020) remains removed, with a focus on deeper understanding rather than surface-level memorization.
Examples of rationalised topics:
Subject |
Removed Topics (Indicative) |
Mathematics |
Some parts of Relations and Functions, Vector algebra examples |
Political Science |
Select case studies from global politics |
History |
Specific sub-sections of certain chapters |
Accountancy |
Reduced repetitive formats in partnership accounts |
Chemistry |
Some portions of Polymers and Chemistry in Everyday Life |
Note: The final rationalised topics list is provided in official subject-wise PDFs.
2. No Further Syllabus Reduction
Despite speculation, the board has clarified there will be no additional syllabus reduction for the 2025-26 session. The rationalisation from previous years remains valid, but no new deletions are being introduced.
3. Two-Exam Format Introduced
CBSE has introduced a two-exam system for Class 12 students starting 2025-26. Students can appear for both board exams in the academic session, and the better score will be retained for the final certificate.
What this means for syllabus coverage:
- Both exams will be based on the full syllabus, not split or term-based as seen during the pandemic years.
- There will be no compartmentalization of topics into Term 1 and Term 2.
- Students must prepare holistically for all units from the beginning of the academic year.
4. Focus on Competency-Based Education
As per NEP 2020 guidelines, CBSE continues to shift toward:
- Case-based and source-based questions
- Application-oriented problem solving
- Analytical thinking tasks embedded in assessments
- Reduced focus on rote-based long answers
This shift is visible across subjects like English, Science, Economics, Psychology, and Business Studies.
5. Changes in Internal Assessment and Practical Evaluation
Internal assessment weightage has been modified slightly in some subjects:
Subject |
Internal Assessment |
Practical/Project Work |
Theory Weightage |
English Core |
20 marks |
Project-based (ASL) |
80 marks |
Physics, Chemistry |
30 marks |
Practical work |
70 marks |
Business Studies |
20 marks |
Project work |
80 marks |
Psychology, Sociology |
30 marks |
Practical-based |

Students are advised to give equal importance to internal work, as it directly affects final grades.
