CBSE Class 10 New Rules 2026: Complete Guide for Science and Social Science Exams
The CBSE Class 10 New Rules 2026 have introduced a major shift in how students will write their science and social science exams. These rules focus on a section-wise answering pattern. Students must now write every answer in the correct section of the answer sheet. If an answer appears in the wrong section, it will not be evaluated. Because of these changes, every learner must understand the new system clearly. This detailed guide from Shiksha Nation will help you prepare for the new exam pattern with confidence.
Why CBSE Introduced the New Rules for 2026
The earlier exam pattern had one major issue. Many students mixed answers from different subjects or chapters. This created confusion during evaluation. As a result, students often lost marks even after writing the correct content. To remove these problems, CBSE added clear rules. These rules separate each part of science and social science into well-defined sections. Therefore, checking becomes easier and fairer.
The CBSE Class 10 New Rules 2026 aim to reduce errors, improve clarity, and make the marking process transparent. This benefits both students and teachers.
Overview of the CBSE Class 10 New Rules 2026
The new rules mainly focus on:
-
Section-wise organisation
-
Strict answer placement
-
Clear separation of subject areas
-
Zero marks for misplaced answers
-
No correction during re-evaluation
-
Better structured question papers
These rules may feel strict at first. However, they will help students write their exams more neatly and score better.

The science paper will now include three clear sections. Each section covers a specific branch of science. Students must write each answer in its correct section.
