The updated course material for Class 10 has been released by the Central Board of Secondary Education. This year, there have been more cuts to the new syllabus for important disciplines. The term-based test system will be eliminated by the board authorities, and the single board exam system will be reinstated. Students can check the whole Class 10 syllabus on the official website.

The updated syllabus for Class 10th is provided below for students to review:
