CBSE Class 10 Board Exam 2026: New Updates Explained

The CBSE Class 10 Board Exam 2026 has introduced major changes to the Science and Social Science papers. According to this, the Science question paper has been divided into 3 sections, and the Social Science question paper into 4 sections. Considering this, students are mandated to write the answers only within the space identified in the concerned section in their answer book. The answer to a section should not be mixed in any other section, but if it is, then it will not be evaluated, and no marks will be allotted.

The CBSE has made new changes in the Class 10 Board 2026 by introducing a section-wise question paper pattern for both Social Science and Science papers. The structure has been redesigned to improve the quality of the evaluation, ensure subject-wise division of subjects, and avoid confusion caused by mixed answers in the answer sheets.

Under the revised CBSE Class 10 Board exam format, the science question paper has been divided into Sections A, B, and C, with Biology, Chemistry, and Physics, respectively. Meanwhile, the social question paper has been divided into Sections A, B, C, and D, with History, Geography, Political Science, and Economics, respectively. 

Important: Students must divide and label the sections in their answer booklet before writing. Each answer should be written only in the concerned section; mixing any of them will not be evaluated, and no marks will be allotted.

The Class 10 CBSE Board Exam 2026 is approaching, and the new rule on how to write and divide sections in the answer booklet during the exam board is creating buzz among students and parents.
