CBSE Class 10 Syllabus 2027: What's New
For the 2026–27 CBSE Class 10 academic session, there are no major changes to the syllabus, such as adding or removing entire chapters. Instead, CBSE is focusing on changes in assessment and question patterns in line with the NEP 2020.
Over the last few years, the CBSE Class 10th syllabus has evolved from a memory-based system into an application-oriented structure. The major changes for the current session are broken down below:
- The Two-Board Exam System: CBSE has structured a dual board exam model. Board Exam 1 is mandatory (held in February–March), while Board Exam 2 is optional (held in May). If a student opts to take both, the higher score of the two in each subject is reflected on the final marksheet.
- Expanded Competency Weightage: Competency-based questions (case studies, source-based graphics, and assertion-reasoning) now command 50% weightage of the entire theory paper across the CBSE 10th syllabus.
| Feature | Old CBSE System (Pre-2023) | Modern CBSE System (2027) |
|---|---|---|
| Exam Frequency | One final exam at the end of the year. | Two opportunities
|
| Question Style | Direct, theoretical, textbook-definition heavy. | Application-heavy (50% competency-based case studies/real-world problems). |
| Textbook Size | Thicker, comprehensive core NCERT volumes. | Rationalised textbooks with roughly 30% lighter content weight. |
Ques. Has CBSE introduced any new evaluation pattern in the CBSE Class 10 Syllabus 2027?
Ans. Yes. While the core NCERT content remains unchanged, CBSE has introduced the Two-Board Exam System and raised competency-based question weightage to 50%, both of which are central features of the CBSE Class 10 Syllabus 2027.

For better performance in the CBSE Class 10 exams, focus on subject-specific preparation techniques along with regular revision and practice.
- Mathematics: Keep a separate formula sheet for quick revision and practise neat diagrams for Triangles and Circles. Standard Maths focuses more on application-based questions, while Basic Maths is more direct.
- Science: Regularly practise and label important diagrams such as the nephron, human heart, and reflex arc. Also, practise balancing at least 5 chemical equations every week.
- Social Science: Write answers in clear, numbered points with suitable subheadings instead of lengthy paragraphs. This makes answers easier to read and evaluate.
- English: Give equal attention to Writing Skills and Grammar. Learn the correct format for formal letters and practise identifying and presenting key data in analytical paragraphs.
