The Central Board of Secondary Education issued a circular detailing the subject-wise mark distribution of Classes 10, 12 practical, project and internal assessment exams 2025. The CBSE Class 10, 12 practical and assessments will be held from January 1, 2026, to February 14, 2026.

CBSE has clarified that each subject carries a total of 100 marks, divided across theory, practical, project or internal assessment as applicable. Schools have been instructed to complete the conduct of CBSE Class 10, 12 practical, project and internal assessment 2025 within the prescribed timeline.

“To aid and assist the schools in smooth conduct of Practical/Project/Internal Assessment and conduct of Theory Examinations, a list of subjects for Classes X and XII containing the following details is annexed with this circular for information with the thought that schools will read this circular and strictly comply instruction and not make a request later on to correct the mistake committed by them by giving various excuses,” the official circular said.

• Class

• Maximum marks (Practical)
• Maximum marks (Project assessment)
• Maximum marks (Internal assessment)
• Whether an external examiner will be appointed for practical/project assessment

The CBSE Class 10 exams 2026 will be held from February 17 to March 10, while the CBSE Class 12 exams 2026 are scheduled from February 17 to April 9. The board revised the Class 10 timetable after student feedback to ensure adequate preparation time and advised Joint Entrance Examination (JEE) Main 2026 aspirants to provide Class 11 details in the application form to avoid date clashes.
