As the 2026 board examinations approach, the Central Board of Secondary Education (CBSE) has released a new circular outlining significant changes to the format of Class 10 Science and Social Science question papers. The revised structure, aimed at ensuring greater clarity, discipline, and fairness in the evaluation process, will be implemented in the upcoming board exams scheduled to begin on February 17, 2026. The Class 10 examinations will conclude on March 10, 2026.

According to the circular, the Class 10 Science paper will now be divided into three distinct sections—Biology, Chemistry, and Physics. Students must replicate this structure in their answer booklets by clearly labelling and demarcating each section before attempting the questions. CBSE has emphasised that answers must be written strictly within the designated sections, and mixing or misplacing responses will not be permitted.

A similar format has been introduced for the Class 10 Social Science paper, which will consist of four sections: History, Geography, Political Science, and Economics. The board has categorically stated that any answer written in the wrong section, for instance, a Geography answer placed under History, will not be evaluated.

CBSE has warned that non-compliance with the updated format will have strict consequences. Answers written outside their designated sections will not be checked under any circumstances, and such errors will remain uncorrectable even during verification or re-evaluation. The evaluation scheme, the board noted, is final and non-negotiable.

To help students adapt to the new structure, schools have been instructed to conduct regular tests, internal assessments, and pre-board exams using section-wise answer sheets. CBSE has also encouraged students to download the latest sample papers from its academic website to familiarise themselves with the revised format.

The board stated that the revamped answer structure is designed to streamline the evaluation process, reduce confusion, and maintain uniformity across scripts. While the rules may appear stringent, CBSE believes the changes will ultimately benefit students by encouraging clarity, systematic writing, and discipline during examinations.

For students appearing in the 2026 board exams, the message is clear: follow the new section-wise format meticulously, as any deviation could result in the loss of marks—with no scope for correction later.
